445nm blue laser pointer
445nm separate crystal lens. Blue laser pointer. The line generator tube is equipped with high-quality optical lens. Compared with officially used plastic lenses or glass coated lenses, true straight alignment will not cause laser attenuation or blurring. Under the maximum working distance of 25 meters, the high power laser pointer line still maintains a high uniformity, maintaining the same line brightness from the middle to the two ends. The whole laser alignment process maintains up to 80% laser beam uniformity. Usually the blue laser emitted from a separate crystal lens is brighter and more visible than the formal optical lens. In the long-distance line alignment process, this 445nm blue laser module has just shown its advantages.

Generally, the green laser pointer has an output direction of 532nm laser wavelength, which is obtained from the 1064nm infrared laser frequency. It is the most common DPSS (diode-pumped solid-state frequency doubled) laser and is more complex than laser pointers made by standard laser diodes (such as red, blue, or blue-violet laser pointers). The 532nm green laser pointer projects the most obvious and brightest green light at night and during the day. The power should be turned off after the 532nm green laser pointer has been pointed continuously for a certain period of time. However, the red laser pointer does not need to do this. The design of green lasers has high power consumption and large heat generation, which will be affected when the operating temperature is too high. In addition, the 532nm green laser pointer can automatically cut off the power when the working temperature is very high to protect the blue laser pointer diode from being burnt out.
