In those of very special night vision illumination field, visible laser is not very applicable, but have to choose IR lasers. The adoption of invisible beam emitting 808nm 400mW infrared laser diode module is just efficient enough to fulfill the need. It gets much similar structure with common laser pointers, but this IR laser module is always able to make continuous IR laser beam radiation without being disturbed.
For instance, according to easy mounting of rechargeable battery box, this 400mW 808nm infrared laser module can be used for military targeting IR laser source. Its invisible IR laser cannot be detected by enemy, thus it is also workable for night hunting, supervision etc. Its IR laser beam is also very stable and reliable in long term work.
