IR 940nm 200mw Line Laser Module for Smart Interactive Whiteboard

This IR 940nm 200mw Line Laser Module is tailor-made for smart interactive whiteboards, delivering reliable infrared line projection to enable precise touch detection and real-time interaction.

This IR line laser module emits 940nm infrared laser—an invisible wavelength ideal for interactive systems. This avoids visual interference with the whiteboard’s display, while its low sensitivity to ambient light (sunlight, room lights) ensures stable performance in bright classrooms or meeting rooms. With 200mw stable output, it projects a sharp, uniform laser line (line width ≤2.5mm@2m) to form a precise detection grid.

In smart interactive whiteboards, this IR 940nm 200mw Line Laser Module works with built-in cameras or sensors to track touch positions. The infrared line’s high contrast against the whiteboard surface ensures fast response to gestures like tapping, dragging, or zooming—critical for smooth teaching or presentation interactions.

The IR 940nm 200mw Line Laser Module integrates seamlessly with mainstream interactive whiteboard systems: supports PWM control signals for easy synchronization with the whiteboard’s mainboard, and its compact design (diameter ≤ 12mm) fits into the whiteboard’s edge or frame without occupying display space. It runs on 5V-12V DC power, with low consumption to match the whiteboard’s energy-efficient design.
