0-45° Wide Incidence Dielectric Mirror / TFVM-50C08-VIS

You can use the 0-45° Wide Angle Dielectric Mirrors for an optical system for reciprocating the light between two mirrors or Michelson interferometer, if you want to use a mirror at an incident angle of 45 ° or less. When used at 45 degree and 0 degree incidence angle, one mirror can be shared to obtain high reflectivity.

◦Very high reflectivity can be obtained between 0 degree to 45 degree angle of incidence.
◦If used at a fixed angle of incidence, it can also be used as a broadband mirror. For example, if TFVM-800 is used in a 45 degree incident, reflectance of 99% or more can be obtained in the range of 730nm to 900nm.
◦Since there is no absorption in the coating there will be very little change in the performance over time and the mirror is durable even with continuous laser irradiation.

Guide ▶Please consult our Sales Division for assistance in your selection and for customized products. (customized on outer diameter, wavelength characteristic
Attention ▶Reflectance wavelength characteristics of dielectric multilayer coating vary depending on the polarization state of the incident beam. Reflectance of P-polarized light is lower than that of the S-polarized light, and the reflection range will also be narrower.
▶When used not in adaptive wavelength, reflectance may be lower.
▶If a mirror is used other than normal incidence, wavelength reflectance characteristics also vary depending on the polarization condition.
▶The reflectance characteristics of the 45 degree angle of incidence listed are the average value of the reflectance of P-polarized light and S-polarized light.
