Features
Thin dielectric films with different refractive indices are coated in multiple layers, and light interference is used to allow the selection of transmission or reflection of light from a light source at the desired wavelengths.
The number of layers of thin dielectric film coated can be from a few to several hundred, which allows various characteristics to be realized.
The shape of the substrate to be coated can be anything from flat to a parabolic mirror.
Applications
Lamp reflectors.
This mirror can be applied to various fields, including laser processing machines.
Example characteristics
Reflecting a reference light wavelength of 950 nm, it can allow high transmittance of a dominant laser light source wavelength of 1,064 nm.
This is a short-pass dichroic mirror not affected by the P- and S-polarized light from a light source.
It is characterized by enabling high reflection of P-polarized light in the reflection band and high transmittance of S-polarized light in the transmission band.
This is an example of allowing total transmission of a dominant laser light source wavelength of 1,064 nm and total reflection of higher harmonics.
It demonstrates its effects in the effective use of laser light source wavelength.
