What is the difference between laser pen red light and green light?

In fact, the choice of green light or red light flashlight laser light can be based on personal preference, but if the range is required to be far away, Xiaobian recommends that friends who have more obvious effects can choose green light, because green is the most obvious effect in laser source RGB. Power and other color range are farther away. However, what is the difference between the laser pen red light and green light? The following small series will introduce you to everyone:

Laser flashlight overview

       Laser flashlight is a semiconductor laser. It is different from the laser pen because its volume is easier to dissipate heat. The laser module is directly in contact with the aluminum flashlight case. The general flashlight module is relatively thick. As shown below, the heat dissipation is better, so it is stable. Sex is better than laser pointer (laser pen is copper shell)! The power of laser flashlight is generally from 5mw to several hundred milliwatts. Some laser flashlights (such as blue laser flashlight) can reach 1w; at the same time, some laser flashlights With adjustable focus function, the laser beam is strong and clear, and the range is far away. Most of them use rechargeable batteries (such as 18650 type rechargeable batteries), some of which have safety locks, and their appearance is like a flashlight.

Light flashlight type

       Mainly divided by light color, can be divided into red light 635-650nm, green light 532nm, orange light 593.5nm, blue purple 405-450nm (450nm already belongs to near blue light), blue light 473nm

price

       The price of laser flashlight is generally more than 100 yuan, the price order is generally red light <blue purple < green light; laser flashlight red light when the laser power is between 150~250, the cost of blue-violet light is obviously rising, red light <green light <Blue-violet (glued crystal laser, non-expensive separation crystal laser)

Problem

       1. After most players buy it, they just play, just match the match and shoot the balloon. There is no special purpose, but be careful not to reverse the battery (mostly the positive one). If the problem is serious, it is possible to put the laser flashlight. Burned out.

2. At night or when it is cold, the laser flashlight becomes dark. At this time, the battery is not powered, but the semiconductor has temperature-sensitive characteristics. At this time, you can use your hand for a while, waiting for the temperature to rise above 20 degrees Celsius. Work, if it doesn't work, consider whether the battery is low. 3, the power of the laser flashlight on the market is not accurate, in fact, 50mw laser flashlight focusing can easily ignite matches, almost kill blackheads. Because laser flashlight is a kind of high-energy-consumption electronic product, a large amount of heat is generated during the lighting process. The order of heat generated by the same power laser is about blue-violet>red-light>green light, and the ability to burn things in green light mainly depends on There is no filtered infrared. Therefore, lasers with a price of less than 1,000 yuan on the market rarely have true pure green light, and there are no infrared filters! Due to various problems caused by heat, the life of the laser is greatly reduced, and the general glued crystal is generally used. Laser flashlight, the use time is recommended not to exceed 1 minute, to be used again after cooling; and the laser flashlight for separating the crystal, the use time is relatively long for 10~30 minutes until the battery is dead! But the laser flashlight for separating the crystal is very expensive. The heat resistance and stability of the bonded crystal are far less than the separation of the crystal, which is the contradiction of the laser, and also limits the ultimate power of the laser flashlight (the green power of the glue crystal is generally only about 200mw, of course, because of the green light Is a very unstable light source, so its peak value is likely to reach 300mw, 400mw is possible), of course, after testing, if there is a good heat dissipation condition, the laser of the glue crystal can be fully lit for a long time, then it must Equipped with a separate cooling fan and a scientifically optimized storage enclosure, these conditions are rooted in a simple flashlight enclosure Impossible to achieve.

       What are the differences between laser pen red light and green light? I hope to know everyone through the above introduction.
