Teach you to use an ignitable laser pointer

Post on: January 10,2019
Many customers have said how to adjust the focus to burn quickly. So in this article, we'll look at a detailed guide to using an adjustable combustion laser pointer.1. Wear goggles. This is very important when you are using a high power combustion laser. Make sure your eyes are protected because a strong laser will hurt your eyes while focusing on burning.2. Remove the filter. Filters are used to change the diversity of the laser beam. When you are ready to burn with a laser pointer, remove the cover so you can get a straight laser beam of 1-5 mm diameter, but it may not be strong enough if you want a fast The way to burn things.3. Reverse the focus of the upper head. After removing the cover, the top head of the laser pointer body can be rotated. By twisting the head, the laser beam lines will change and cross each other. Now find the intersection of most of the laser beam lines, which is the best place to burn.4. Put the matches, cigarettes, or other things you want to burn in focus, and soon burn off the objects and emit smoke, and within a few seconds, the objects will be hot enough to ignite.If you have further questions about this process, you can contact us for further assistance with

The purpose of some people buying laser pointers

Post on: January 03,2019
Many people now come to buy laser pointers, because the purpose of laser pointers is very wide. If you don't know the purpose of laser pointers, please see the introduction of this article.Teacher/Lecturer - For classroom instruction, it is like an infinite extension of the pointer, allowing you to easily indicate any position on the blackboard in any corner of the classroom without having to walk around the blackboard.Business People / Conference Spokesperson - For product presentations and conference presentations, make your presentations free and communicate with customers more easily and naturally.Showroom/Guide - When you are helpless with the goal of “Tifficult to reach”, it can help you get the target out easily and accurately.Wild Traveler/Explorer - Conduct wilderness adventures, direct distant targets and send distress signals to make your trip more enjoyable and safe.Astronomy Enthusiast - For the astronomical star, the green laser beam is a very beautiful green line that is suitable for observation in the night sky and can help you point out the position of the star.Construction site/mining site - For remote and accurate indication of buildings, you can avoid being close to dangerous areas, making you like a field conductor.Self-defense - When you are hit by a dangerous animal in the mountains, or when a criminal robs, your life and property are threatened, you can use a laser pointer to defend, you can use a high-power laser pointer to scare the enemy.In addition, I want to emphasize that the laser pen is not a toy, the laser is a dangerous thing, do not use the laser pen as a toy for children.

Laser stands for Light Amplification by Stimulated Emission of Radiation. A laser is a device that projects a highly concentrated narrow beam of light which is amplified to great brightness using stimulated radiation.Lasers are used for a variety of purposes including pointing out objects during a presentation, aligning materials at construction sites and in the home, and by doctors for cosmetic and surgical procedures. Many items you encounter on a daily basis use lasers, including CD and DVD players, bar code scanners, dental drills, laser-guided tools, such as levels, and laser pointers.What do you mean by laser "radiation"? Some lasers emit radiation in the form of light. Others emit radiation that is invisible to the eye, such as ultraviolet or infrared radiation. In general, laser radiation is not in itself harmful, and behaves much like ordinary light in its interaction with the body. Laser radiation should not be confused with radio waves, microwaves, or the ionizing x-rays or radiation from radioactive substances such as radium.The more efficient crystals are likewise more valuable so we must charge more for our lasers that use them.Why are lasers uniquely hazardous?Two characteristics of laser light contribute to the hazard:Laser light can be emitted in a tight beam that does not grow in size at a distance from the laser. This means that the same degree of hazard can be present both close to and far from the laser.The eye can focus a laser beam to a very small, intense spot on its retina, which can result in a burn or blind spot. So the goggle is important.

What is the difference between a laser pointer and a handheld laser

Post on: December 19,2018
1. The low-power laser pointer selects the pen design, and the high-power laser selects the hand-held flashlight design to get more space for the larger laser module. High power handheld lasers require more space as their thermal stability system. Handheld lasers always add the ability to adjust the focus and safety key protectors.2. Different operating hours. The laser pointer has a maximum brightness of no more than 15 seconds and then cools down for 10 seconds. Hand-held lasers indicate continuous illumination for no more than 3 minutes.3. Hand-held laser adopts adjustable focal length design to provide customers with more practical functions.In high-power lasers, the blue laser is a high-power representation. Let's take a look at the blue laser pointer.The blue laser with a fascinating and attractive sapphire blue laser beam is very popular among laser amateurs and professionals.Laser enthusiasts even use high-power blue lasers for various combustion experiments. When users use high power blue lasers, users should pay attention to:1. Long-term continuous combustion will cause extreme heat, which will affect the service life of the laser tube and then burn out. The recommended pointing time is 30 seconds and cools down.2. Correctly install the battery positive and negative blue laser pointer3. Be careful of dust, do not use blue laser in smoke and water vapor environment4. Close-range blue laser pointing at the object, the user should pay attention to the laser diffuse, reflect and refract light, and prevent eye damage.5. The safe operation of the blue laser should not illuminate flammable substances, humans and animals.6. Remove the battery when you are not using the blue laser, just place it in the correct position.

Several key issues with laser pointers

Post on: December 11,2018
What is the price difference of the laser pointer?Laser pointers with different output powers and wavelengths produce different production costs and different technical requirements. For example, a green laser and a 200mw red laser get the same price range. Red lasers above 300mw are more expensive.Blue lasers, especially high output power, have lower requirements on raw material costs and technical requirements. It is always available at a lower price.When the laser pointer beam is visible?If you choose a very low output power, you will not see the laser beam at night and during the day. The beam of the 532nm green laser pointer up to 30mw is clearly visible. During the day, the green laser beam can even be seen indoors. A higher output power laser pointer results in a stronger and more intense green laser pointer beam.Which output power laser pointer can be used as a combustion laser?Higher power laser pointers always have a higher burning capacity. The laser pointer rises 100mw for easy combustion matching. The 200mw laser pen can burn cigars, cut tapes, and popular balloons.What is the difference between a red laser and a green laser?The red laser wavelengths are 635 nm and 650 nm, and the green laser wavelengths are 515 nm, 520 nm, and 532 nm. Different wavelengths of laser light produce laser beams and spots of different colors during operation. A red laser with a certain output power has a better burning power than a green laser.Different laser characteristics make the visibility of the red laser beam much weaker than the green laser with the same power. Green lasers can achieve brighter and more pronounced green laser beam radiation. The user can determine the quality of the laser pointer only with exact requirements and personal preferences.

What laser you want

Post on: November 27,2018
Many customers want to buy a laser pen but don't know how to choose it. Today I will introduce the use of various types of laser pointers so that you can better choose the laser pointer that suits you.Blue, green and purple laser pointer features:The illumination point of the laser pointer depends not only on the output power and apparent brightness of the laser reflected from the surface, but also on the color version of the human eye. For example, the human eye is most sensitive to the visible spectrum wavelengths of 520 nm to 570 nm and less sensitive to red and blue laser wavelengths. As a result, the 532 nm green laser is brighter than other color lasers having the same output power.Blue laser pointerThe blue laser pen was originally produced by the 473 nm DPSS blue laser and is very expensive and unstable. With the development of CASIO, including high-brightness projector hybrid light sources made of 445nm blue laser diodes, very high power 445nm portable lasers are being developed and widely used.Laser technology engineers also developed blue laser pointers made of 450nm blue laser diodes. Its output power is 1mW and 5mW. The projected blue laser beam is very pure, slightly closer to blue-violet.Green laser pointerIn astronomical research, laser amateurs or astronomers may use a Class IIIa 532nm 5mw green laser pointer for stargazing. This type of laser pointer is widely used by leading astronomy enthusiasts to point to stars, constellations and other celestial bodies. The green laser beam is only visible in very dark operating environments. Astronomical observers do not need to choose high power lasers.Blue-violet laser pointerMade of 405nm blue-violet laser diode, the blue-violet laser pointer is a semiconductor laser that is close to ultraviolet light. Low visibility, but can stimulate fluorescence. It is suitable for banknote testing and chemical inspection.Hope you can find best laser you want.

Laser Pointer Usage Taboo

Post on: November 23,2018
1. The laser is harmful to the human eye. Do not direct it to the human eye. Please keep away from children to avoid accidents. When using the laser indoors or at close range, wear a laser-shield of the appropriate wavelength. Avoid direct beaming to the eyes.2. Please do not illuminate the laser for a long time (especially the  green laser). It is best not to exceed 30 seconds in the summer. If you  feel the laser flashlight or the pen is hot, please stop it immediately  until it is completely cooled.3.  When using in winter, the green laser may need to be warmed up for a  period of time to achieve the best brightness. It can be placed in the  pocket and then put into the battery. The continuous lighting time  should not exceed 1 minute. In order to prevent the laser from aging too soon, or overheating, it will cause damage to the laser LD or the module.4. In the art gallery, because some paintings may be afraid of light, it is not suitable to use a laser pointer.5, in the zoo, in order to avoid scaring animals, should not use a laser pointer.6. When astronomy enthusiasts use a laser pointer to point to the  star, they should pay attention to it. They should not use the star pen  frequently and for a long time, so as not to hinder other people from  watching stars and photography.7. In public places where there are many people, in order to avoid  accidental injury to others, the laser pointer should be stopped.8.  Some high-power laser pointers have obvious thermal effects and cannot  be used continuously for a long time, especially for solid-state lasers  that are sensitive to temperature.

How to choose a best green laser pointer

Post on: November 09,2018
  1. Carefully observe the green laser spot in a dark place. If there is a clear floodlight, the laser light lens will fail.  2. Check if the green laser spot is a complete dot, usually in the 2mm diameter range.  3. Check if the green laser pointer's laser beam brightness changes from bright to dark. If so, there may be problems with the laser pointer board and the laser diode.The 5mw green laser pen belongs to the Class IIia laser with a wavelength of 532nm and uses two aaa batteries. This green laser projects a 532 nm green laser beam with high brightness and is therefore extremely dangerous to the eye, especially high power lasers. In many countries and regions, only 5mw of green laser pointers are allowed.Wild travel, hiking and adventure. Outdoor enthusiasts can use the green laser pointer for long-range target aiming and rescue signal pain. Mining and construction workers can use the green laser pointer for accurate and precise projection and measure over long distances. It avoids access to dangerous areas.

Safety use of laser pointer

Post on: November 01,2018
Avoid direct contact between the laser and the flammable product. High power lasers are more dangerous. Do not operate the laser pointer at ambient temperatures of up to 35 degrees Celsius or below 0 degrees Celsius to avoid accelerated laser aging. The continuous working time of the laser pen should not exceed 2 minutes in winter and should not exceed 1 minute in summer to prevent aging. If you do not use it for a long time, be sure to remove the battery. Place the laser pointer in a place where it is protected from moisture and static electricity.The safety of the laser is very important when using the laser pointer. Never point it at your eyes and other vulnerable areas and prevent laser light from reaching your eyes. The laser pointer passes through the complex lateral direction of the 1064 nm infrared laser and is finally converted to a 532nm laser. It cannot project a laser beam directly from a laser diode. It leads to higher production costs for lasers, but it is always safer.How is the laser pointer suitable?Teaching, speaking or speaking. Laser pointers are the most common application in teaching. It is a modern mold or equipment. Its application is just to keep the speakers off the stage and to use them anytime, anywhere. It has done a great job in speeches, speeches, business meetings and more.Astronomical stargazing and constellation observation. Laser pointers are very popular among laser amateurs and astronomers because of the most obvious and sensitive laser projections. The high power laser pointer projects high-intensity laser beams and spots at night. Laser amateurs can use it for clear stargazing, constellation observations, low clouds and other celestial bodies.If you have any questions, you can ask us and we will get back to you as soon as possible.
