High Surface Accuracy Mirrors are realized by optimizing the conditions of the substrate material, thickness and coating. A surface accuracy of λ/10 after coating is guaranteed on these mirrors.

◦This product features a surface accuracy (after coating) higher than our standard dielectric multi-layer flat mirrors (TFM).
◦By using synthetic fused silica and increasing the substrate thickness the rigidity of the mirrors are increased.
◦Our product line includes mirrors with high-reflection for use in individual wavelengths including ultra-violet,YAG and other lasers.

Attention

▶Surface accuracy data is not provided standard with the product. Please contact our Sales Division for this data at an additional charge.
▶For the dielectric multi-layer film, the reflection rate wavelength characteristics vary depending on the polarization state of the incident beam. The reflection rate of P polarization is lower than that of S polarization and the reflection band is narrow.
▶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.
▶If the product is not used at an applicable wavelength, the reflection rate may decrease.
