What about think the red laser sights better than green laser sights

Post on: July 13,2018
   What about think the red laser sights better than green laser sights?   Some laser's lover talk me about this question. I think it depends on the environment and time of day.   In many situations, green tends to perform better, especially outdoor. The problem with the red lasers is that there are more reds in the sky and it tends to wash out the red in your laser. In contrast, there are less green lights in nature, so it's harder to wash out the green laser.    In indoor type situations, you can virtually flip a coin. Just remember, lasers work both ways.   Actually, the green ones are considered better and have a much higher price tag as well. Red laser sights can be hard to see in daylight. Green ones appear brighter in those conditions. In the same power, green laser is more visible than red laser.   The red ones have been around for a long time because the engineers figured out how to mass produce them before they figured out the green lasers.   Simply because neon green is easier seen by the human eye. Green is a more accepting color for your eyes. Also teacher like red laser.   So, what do you think about?

The difference of laser light and LED light

Post on: July 06,2018
   Laser refers to the amplification of light by stimulated emission of radiation. LED light refers to LED.   The LED is a diode. The LED is just a semiconductor diode (p-n) junction that emits a broad spectrum of light. The light will not be the same. We have different types of LEDs that can produce different colors (or wavelengths).   When it comes to lasers, LASER is the name of a technology that is used to generate a coherent beam by stimulated emission. If there are gas lasers, semiconductor lasers, solid-state lasers, etc., there are many types of lasers.   The biggest difference is that the laser emits coherent light, while the LED emits only colored light.  So the LED lights up everything like a candle, and the laser emits a beam of light. A semiconductor laser is a laser similar to an LED.  A particular laser emits a specific wavelength. And there are so many lasers emitting visible and invisible spectra. Compared with LEDs, the emission spectrum is very narrow.   Laser is a device that produces a coherent and focused beam. But the LED is not focused and it has a diffused beam. It is used for flashlights. The laser produces a straight path of a high intensity beam. And led is an omnidirectional light source.   For the difference between the two, there is no need to go deeper. Just know that one is direct light and the other is radiation.

What does laser mean

Post on: June 14,2018
   A laser is an artificial light whose brightness is 10 billion times that of the sun.       The principle of laser was  discovered by famous American physicist Albert Einstein in 1916, but it was not until 1960 that the laser was successfully manufactured for the first time.  It is called the fastest knife, the most precise ruler, the brightest light and the magical laser.  Laser drivers are an important part of laser generation.  Physical lasers represent light amplification through the stimulation of radiation.       Optically, it is a device that   emits light by optically processing the stimulated emission of electromagnetic radiation.     Lasers can be used for different purposes for industrial, medical, physical research and other possible uses. If you need more details.        You can find answers in any   book on laser physics.  A laser is a device that emits light through an optical amplification process through the stimulated   emission of electromagnetic radiation.  The term "laser" originated from the acronym "radioactive light amplification."       By using a high voltage, an   inert gas and a reactive gas can be generated at an appropriate temperature   and coherent light, and then optically, focusing and orientation can be performed.    

Why are cat like laser

Post on: June 05,2018
   In recent days, many animal lovers have come to consult with laser pointers and can play with cats. I can't say exactly why cats are interested in laser pointers, but I can ask why animals are particularly crazy about something.          Lasers that shine on the floor, walls, or plains naturally kill the cat's prey. They never really caught it, so assign them to keep hunting. Many animals have a fixed pattern of behavior in their behaviors, in which certain stimuli (called release stimuli) cause them to behave in a certain way each time the stimulus is presented.       Many years ago, researchers discovered that they could isolate certain aspects of the release of stimulants and make the animals' behavior predictable.      The most famous example is that they show the seagull chicks with red dots on a cane and keep them begging. The red dot worked because the mothers of the gulls had red spots at the end of the pipa. Despite this, the light spots produced by the laser pointer are likely to mimic something in the early evolutionary feline environment, causing them to chase and attempt to capture it.    It may imitate some kind of food. Maybe it was the light of the night.       The cat's eyes are carefully evolved to track shiny things and movements. Sparks are equal to the eyes of animals and the wings of insects. Movement equals potential predators or predators. The laser is an artificial thing. It only manipulates these characteristics and is perfectly satisfactory for most cats. Cats like laser pointers because they have the instinct to chase and catch. For cats, the laser beam mimics animal activity in the wild. However, the trouble with laser pointers is that they are games that cats cannot win. Your cat can chase the laser until it drops, but it has never been satisfactorily captured and unsatisfied.     If you have a better idea, you can write to us.    

What is the difference between a red laser and a green laser

Post on: May 25,2018
   In my opinion,green lasers look brighter for the same power, as we perceive better in green. They usually have tighter mode structure, a smaller, more intense beam.   High power Green Lasers Pointer are getting more and more popular. Green Lasers is astronomical observation assistant, stars and celestial body pointing. Green Lasers emitting in the green part of the spectrum are widely available to the general public in a wide range of output powers. Green Lasers Pointer outputting at 532nm (563.5 THz) are relatively inexpensive compared to other wavelengths of the same power, and are very popular due to their good beam quality and very high apparent brightness.  Green lasers have a wide variety of applications, including pointing, illumination, surgery, lasers light shows, spectroscopy, interferometry, fluorescence, holography, machine vision, non-lethal weapons and bird control:   The Red Laser Pointer is the wonderful gift. The Red Laser Light adopts the latest technology optics and microelectronics and becomes some of the most popular high-tech gadgets to hit any global market. You can find High Power Red Lasers in Red's wavelength has been an important factor in lasers technologies. Red Lasers emitting in the red region of the spectrum have been available since the invention of the ruby lasers in 1960. In 1962 the red helium–neon lasers was invented, and these two types of lasers were widely used in many scientific applications including holography, and in education.  Portable, high-powered versions are also available for various applications:      If you are still hesitating about the choice of laser pointer, you can contact me and I can give you good advice.

About flashlight laser

Post on: May 19,2018
   Someone ask me for flashlight laser? It seems that people's demand for flashlights is also very large. Our website also launched a laser flashlight,,and there are more people to buy.    Two flashlights are recommended for outdoor camping. If you do not want to carry an extra flashlight, the other feature with an worlds brightest led flashlight is to set it to ""dimmed"". Most best flashlights have a switch that can be set to dim or bright light.      In the long run, getting an LED flashlight can save you money because you don't have to replace the battery as often as an ordinary incandescent bulb battery. The brightest LED flashlight has ten times the battery power than an ordinary incandescent the brightest flashlight in the world, and the bulb can last up to ten years, so you don't have to worry about its bulb burn out.   With the hi-power LED bulb as the new lighting source which owns the great features and benefits: Higher intensive brightness, longer light distance, energy saving and environmental protection ,no mercury, no harmful rays, no electromagnetic interference on the environment.   Working areas: rescue and relief work,family's light .It can also be used for patrolling in industrial and mining enter-prises as emergency light.   If you are still looking for what kind of laser flashlight to buy, you may wish to look at my latest flashlight, which you deserve.

Whats the difference between laser pointer and flashlight

Post on: May 14,2018
   Laser is an radial and the flashlight emits a relatively wide spectrum of light from a multi-directional light source. The light is focused in a general direction by a parabolic mirror.   Flashlights are designed to provide directional lighting for relatively short distances.It pervades and loses strength quite quickly.   On the other hand, the laser beam diffuses very little and maintains long-range intensity. However, such a compact beam of light, finding its own way in the dark is not very useful. When you are tired of the FAA's troubles, you can now easily convert it into a bright white flashlight.   The flashlight laser is a simple adapter that converts the Arctic-focused blue laser into a diffuse white 500 lumen beam, so it can be used as a relatively safe flashlight.   The multifunctional flashlight illuminates things in three ways. Universal work tool, it integrates laser, ultraviolet and LED lights. The LED light feature provides two lighting levels that allow you to adjust the flashlight according to specific lighting conditions to improve your vision.Practical clips and magnetic positioning mechanisms allow your hands to release other tasks.    Thanks to the integrated magnet, the flashlight can also be positioned according to the requirements of most electrical enclosures, allowing the user to point the light source in the desired direction for the task at hand.   For example, an integrated laser can fix positions more precisely and perform projection measurements when lights are installed on the ceiling. Delaying the start interval by 2 seconds prevents the laser from starting accidentally. Due to the integrated UV lamp, the flashlight is also very suitable for technical inspections.   Here is the flashlight laser light you can see:   OK, above is the difference between a laser pen and a flashlight!

About the laser pointer

Post on: May 07,2018
  Today,I want to discuss with laser safety level.Responsible laser owners should take some time to fully understand the FAA regulations surrounding the use of laser pointers. Laser has 5 class,class more higher,the laser's power is too high.   Class I   Inherently safe; no possibility of eye damage. This can be either because of a low output power,or due to an enclosure preventing user access to the laser beam during normal operation.Just like  the teach laser.   Class II   The blink reflex of the human eye will prevent eye damage, unless the person deliberately stares into the beam for an extended period. Output power may be up to 1mW.   Class IIa   A region in the low-power end of Class II where the laser requires in excess of 1000 seconds of continuous viewing to produce a burn to the retina.   Class IIb   Lasers in this class may cause damage if the beam enters the eye directly.This generally applies to lasers powered from 5–500 mW. Lasers at the high power end of this class may also present a fire hazard and can lightly burn skin.Just like burning laser pointer.   Class IV   Lasers in this class have output powers of more than 500 mW in the beam and may cause severe, permanent damage to eye or skin without being magnified by optics of eye or instrumentation.If you want burning laser,need to goggles,it's very important for us.       Safety Recommendations for Laser Pointers   The use of laser pointers has become widespread. The laser pointers are useful tools for educators in the classroom and at conventions and meetings. However, due to the low cost and ubiquitous supply, these laser pointers are now being purchased and used by the general public, including children, and used in ways not intended by the manufacturers. As a result, serious concerns about the hazards of laser pointers have surfaced.   The hazards of laser pointers are limited to the eye. Although with most visible lasers, the largest concern is potential damage to the retina, most laser pointers are not likely to cause permanent retinal damage. When you use high power laser,please remind,need  goggles to protect your eyes.    This one is best suggest:200-560nm Eyes Protective Goggle Glasses with Glasses Cloth .

Red laser pointer, your first choice

Post on: April 26,2018
  Red Laser Pointers are the simplest laser pointers which can be battery-powered laser pointer.Red laser pen can completely free the user from the computer, users do not have to keep the computer next to the computer, when the user in the electronic teaching, presentation and report speech, when the key content needs to be note, only lightly press the hand, the red color laser point can be mapped in the need to emphasize the text. On the screen, you don't have to "touch" with the audience or "close contact" with the projection screen every time you explain the key content. At the same time, the user can only gently point out the relevant functional buttons to turn the electronic manuscript to the user's page, up and down, 360 degrees unrestrained; No matter in any corner of the classroom, in the lecture hall, or in the back of the conference room with the listener, the screen will automatically appear on the screen, and the computer is no longer necessary. Change the page's heart, really reflect the wireless clicks, get infinite wonderful!   In addition, as the industry matures, many additional functions are applied to the laser pointer itself, such as U disk storage function, such as gift function. And the portable and with richer applications laser pointer is a good guide for your traveling,If you still hesitate to choose what kind of laser pen, you might as well buy a red laser pointer first.
