Laser
viewing cards convert
UV/ infrared
radiation to visible
radiation providing
a visual image of light. The cards consist of an
UV/ infrared
phosphor material which 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 in the form of visible light.Hand-held
viewers are ideal for observation and
alignment, of laser beams with wavelengths
between 250nm and 13um. The viewer delivers a
bright, high-contrast image with edge-to-edge
sharpness. |
