· A substrate polished on both sides of a glass substrate in parallel.
· It can be used as a substrate for coating made-to-order beam splitters and windows, etc., with a vapor deposited film.
· A BK7 type parallel plane substrate that can be used in visible and infrared regions.
· For those with high parallelism, the angle of the transmitted beam will not change even if a parallel planar substrate is inserted perpendicularly into the optical path of the laser.
· Those with high surface accuracy can be used as substitutes for test plate glass.
· A wedge substrate (WSB/WSSQ/WSSQK) is also available, preventing any influence of reflection off the reverse face.
· * The parallel planar substrate has a loss of 10% due to reflection from the front and back surfaces.
· * No surface accuracy guarantee data is included with this product.
