The blue and green light of the laser flashlight corresponds to light with wavelengths of 473nm and 532nm, respectively.
1. Classification
1. Divided by wavelength
It can be divided into red light 635-650nm, green light 532nm, orange light 593.5nm, blue-violet 405-445nm (445nm is already near blue light), pure blue light 473nm, and invisible infrared 808nm, 980nm, 1064nm.
2. In the light-emitting method
(1) It can be divided into LD to emit light directly, such as 650nm, 635nm, 445nm.
(2) Crystal pumped infrared light, typical 532nm green light, 593.5 yellow light.
3. Introduction to Laser Flashlight
1. The official name of the laser pointer is “Laser pointer”, which is different from ordinary laser pointers and stylus pens in that its shell is similar to ordinary flashlights, with larger volume and usually higher power.
2. The visible laser is designed to be portable, easy to hold, and a pen-shaped transmitter that is processed into a laser module (diode). Common laser pointers include red light (650-660nm), green light (532nm), blue light (445-450nm), and blue-violet light (405nm).
