This is an absolutely particular gadget for all infrared laser owner – IR detection card. It’s just an occasional encounter when I am in search of an infrared laser from LaserTo online shop.
Shares the picture of my IR detection card:
This small card is designed with phosphor addition on...
Re: how to generate infra red for 100m range
Since infrared laser beam is invisible to eyes. It is not easy to see the intense infrared beam at 100m range. You can detect infrared beam with an IR detection card to test the beam range of infrared laser.
It might be more convenient to use a optical fiber detector to instead of PIR detector. An optical fiber detector can make very long distance fiber test.
