◦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. |
