808nm 100mW Semiconductor Laser Coupled PM Optical Fiber

808nm fiber-coupled laser uses PM fiber coupling, which has the advantages of high coupling efficiency and good output laser beam quality. The TEC temperature control system is used to ensure that the laser is more stable and has better performance. Compact structure, strong and reliable, suitable for various industrial and scientific research applications.

This is 808nm 100mW infrared lab laser system coupled PM fiber. The working voltage is AC 90~240V and supports wide range voltage. Its laser power can be adjusted from 0~100mW, and it supports two working modes of CW/Modulation.
808nm is infrared laser, invisible laser, here use infrared sensitive film to observe the spot.
