HTFM-30C08-532 Mirror

[Features]
· By optimizing the material and thickness of the substrate and the coating conditions, a mirror with high surface accuracy has been realized.
· Guarantees surface accuracy of λ/10 after coating.
· A higher surface accuracy (after coating) than the conventional multilayered dielectric flat mirror (TFM) is provided.
· By using synthetic quartz for the substrate and making the substrate thicker, the rigidity of the substrate has been increased.
· A line-up of high-reflectivity mirrors is provided to support the individual wavelengths of ultraviolet lasers and YAG lasers.
· HTFM-MHG, which features a mirror adhered to the holder and guaranteed surface accuracy, is also available.
· * Reflection wavelength characteristics may vary depending on the polarization state of incident beams for dielectric multi-layer film.
· * P polarization has lower reflectance and a narrower reflection band than S polarization.
· * Reflectance for the specification shows average reflectance values of P polarization and S polarization.
· * Reflectance may decrease when used with an incident angle other than 45°.
· * When used at incompatible wavelengths, the reflectance may decrease.
· * No surface accuracy guarantee data is included with this product.
