We are often exposed to infrared light, such as near-infrared wavelengths such as 780nm and 808nm, and the naked eye can see a faint red spot. As we all know, lasers like 915nm are invisible laser. So how do we detect it? Let’s check it now.
In the video, we use a small infrared detection card to convert 915nm invisible light into visible light. The 915nm laser illuminates the observation card and displays a green visible spot.
The size of the detection card can be customized.
