Laser Viewing Cards
The IR laser viewing cards can convert invisible near-infrared light into visible light, thereby enabling observation and tracking of near-infrared light beams. Its principle is to use upconversion fluorescent materials to emit high energy short wave light excited by low energy long wavelengths, generally referring to the conversion of near-infrared light into visible light. Gu Optics' IR laser viewing cards are suitable for observing near infrared light at 800-1400 nm. Our laser viewing card has a photosensitive area extending to the edge of the card, and a handheld area is set at the other end, making it easier for you to align with the optical path.
