Overview

Instant Visualization: Making Invisible Beams "Seen"

The VenusLab Infrared Detection Card is the essential "Beam Guide" for every optical engineer and laser operator. In Infrared (IR) and Near-Infrared (NIR) applications, the invisibility of the beam often makes alignment and module debugging difficult and hazardous.

Our detection cards utilize high-sensitivity photon-conversion materials that instantly absorb invisible IR radiation and convert it into a bright, clear visible spot (typically green or orange). Requiring no electronics or power, it allows you to easily locate beam positions and profile shapes with just a simple pass.

Typical Applications

Laser path alignment
Fiber coupling testing
Beam mode analysis
IR remote/sensor testing
