Laser Display Card

Laser display cards convert infrared radiation to visible radiation providing a visual image of infrared light. The cards consist of an infrared phosphor material which stores the energy from conventional light sources (e.g. indoor room lighting, sunlight). As incident infrared light stimulates the phosphor, the stored energy is released in the form of visible light.Hand-held infrared viewers are ideal for observation and alignment, of laser beams with wavelengths between 700 and 1550 nm. The viewer delivers a bright, high-contrast image with edge-to-edge sharpness.
