INFRARED (IR) LASER TEST CARD

By converting kinds of invisible near infrared wavelength beam into visible light, IR Laser Test Card is able to detect, track, proofread and identify infrared beam efficiently from various kinds of semiconductor lasers, YAG large laser, IR LED etc. and also been applied in fields of optical fiber communication and medical inspection etc.

It's a kind of power, ceramic or glass agglomeration made up of up conversion phosphor with average particle size arranging from 0.4μm to 50μm. It has characteristics as sensitive response, rich glowing color, high concealing ability and reliability, easy test and long lifetime etc.

It functions with 1mW of IR Laser sources, efficient excitation wavelength arrange mainly from 800nm to 10600 nm.

Different wavelength IR laser can be identified by the same IR Test Card; Its brightness will go up along with IR devices excitation power increasing;

Visible Emitting spectrum: Orange red 580-620nm, Blue 430-450nm, Green 530-560nm;

Paper, plastic, glass, mental, and ceramic material test cards are available; Specifications, shape, color etc. can be made according to customers’ requirements.
