High Surface Flatness Mirror 25.4mm Diameter 248nm

HTFM-25.4C08-248

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.

Guide
  • These mirrors are available mounted in a holder with surface accuracy guaranteed (HTFM-MHG), contact our Sales Division to assist in your selection.
  • WEB Reference Catalog Code/W3003

  • WEB Reference Catalog Code/W3800
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.
