820nm dot laser module

custom 820nm laser module

Φ12×40mm near-infrared (IR) dot laser module with 820nm wavelength and 50mW output (Class 3B), equipped with an adjustable focus collimating lens (coated glass or PMMA) and built-in APC constant current driver.

The 820nm IR beam is invisible to the naked eye yet highly responsive to silicon-based sensors—ideal for optical alignment, photoelectric sensor triggering, LDS obstacle detection, night vision auxiliary illumination, and lab instrumentation requiring a stable medium-power IR point source.
