• Use a 0°-45° dielectric mirror when using a mirror at an incidence angle of 45° or less, such as a Michelson interferometer or an optical system that shuttles light between two mirrors.
• When the angle of incidence is used at 0° or at 45°, the mirror can be used in common and high reflectivity can be obtained.
• Very high reflectivity is obtained between 0° and 45° angle of incidence.
• If the incident angle is fixed, it can be used as a wideband mirror.
• Since there is no absorption in the film, there is little change over time and it can withstand continuous laser irradiation.
• We also have a Surface Accuracy Guarantee Mirror (HTFM) that guarantees surface accuracy after coating.
• * Reflectance wavelength characteristics of dielectric multilayer films vary depending on the polarization state of the incident beam.
• * P-polarized light has a lower reflectivity and a narrower reflection band than S-polarized light.
• Reflectance may be low when the watch is used at wavelengths other than those indicated.
• * When the angle of incidence is set, the reflectance wavelength characteristic also depends on the polarization azimuth.
• * Reflectivity characteristics at an incidence angle of 45° are expressed as the average values of the reflectivity of P-polarized light and S-polarized light.
