Infrared laser detection card (board), also known as infrared up conversion card, frequency multiplier, infrared detection card and imaging card, can convert various invisible near-infrared band beams into visible light, effectively realize the detection, tracking, calibration and identification of infrared beams, and can be used for near-infrared light detection of various semiconductor lasers, light tracking emitted by infrared light-emitting diodes YAG and other large laser beam calibration, optical fiber communication signal detection and other fields. The infrared detection board is made of up conversion luminescent materials. The powder or ceramic and glass blocks with particle size of 04pm ~ 50pm can be lit up by using 03mw infrared light source. The effective light excitation band is mainly 700nm ~ 10600nm. The same detection board can identify infrared lasers in different bands. The emission intensity is proportional to the excitation power of infrared devices. The products include paperboard, plastic, glass The area, shape, size and color of metals, ceramics, etc.
