808nm 300mW Infrared Laser Module | Dot / Line / Cross, Adjustable Focus | Interactive Projection Positioning Sight

Product Description

This 808nm 300mW infrared laser module supports 3 switchable output modes: dot, line and crosshair. Featuring adjustable focus, constant-current drive and built-in power circuit, it is widely used for interactive projection, touch screen positioning, industrial alignment, night vision auxiliary lighting and laser sighting.

The infrared beam is invisible to the naked eye. Built with imported laser diode and aluminum heat dissipation structure, it delivers stable output and long service life. Reversed polarity protection is integrated for safer operation.
