Laser Viewing Card

$0.00

Laser viewing cards convert UV/infrared radiation to visible radiation providing a visual image of light. The cards consist of a UV/ infrared phosphor material that stores the energy from conventional light sources (e.g. indoor room lighting, sunlight). As incident UV/ infrared light stimulates the phosphor, the stored energy is released as visible light. Hand-held viewers are ideal for observing and aligning laser beams with wavelengths between 250 nm and 13 um. The viewer delivers a bright, high-contrast image with edge-to-edge sharpness.
