990-0846 VIS & IR Laser Detection Card Laser detection card has a sensitive active region which can be used to visualize weak power laser beams, to detect beam reflections or scattered IR laser light. Proper function of this card requires charging it with visible/ day light before use. Additionally, because emissions from the active region are not Specifications Model persistent, the user must move the card around for optimal brightness of the beam spot.
