Wide Angle Dielectric Mirror 25.4mm Diameter 5mm Thick Wavelength 400 - 700nm

Ref:207149
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.

Data sheet Wide Angle Dielectric Mirror 25.4mm Diameter 5mm Thick Wavelength 400 - 700nm

Description

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.
