Frameless mounting is designed to minimize product footprint and maximize the front surface area of the mirror used. Our high-reflectivity mirrors are produced using a ceramic material with thermal expansion ratio equivalent to Zerodur® to provide maximum thermal stability.

◦Laser damage threshold of the mirror is equivalent to our high power dielectric laser mirrors (TFMHP).
◦λ/10 surface accuracy guarantee after coating.
◦The Beamsplitter coating is equivalent to our ultra broadband dielectric half mirror (PSMH).
◦Fused Silica is used for our beamsplitters to minimize transmitted wavefront error(s).

Attention

▶Surface accuracy data is not provided standard with the product. Please contact our Sales Division for this data at an additional charge.
▶The reflectance specifications are represented by the average of the reflectance of P polarized light and S polarized light.
▶If the product is used without setting the angle of incidence to 45 degrees, the reflection may decrease.
▶Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
