Introduction of Laser Shielding Plate
Our laser shield plate has shielding (laser shielding) performance of optical density*4-6 against
various laser wavelengths, and is useful for safety measures for workers. Compared to commonly used
PMMA (acrylic resin), our laser shield plate is designed to maximize the high flame resistance,
chemical resistance, alcohol resistance, and impact resistance of PVC (polyvinyl chloride resin),
which is the base material.
*Optical density is the logarithm of the degree of absorption, and its relationship to transmittance
is shown in the table below.
