MIRRORS 

Laser mirrors are formed as low-absorption multilayer dielectric coatings on the surfaces of YAG, Nd-glass, ruby, alexandrite, and other solid-state laser materials, or on the surfaces of other laser optical elements. Appropriate choice of the coating material and thickness and the number of layers enables desired reflectance and transmittance characteristics to be produced at a desired wavelength region.

Wavelength Range       193nm to 10.6um

Reflectance     approximate 0.1 % to 100%.

Typical spectral characteristics

Besides the desired visible light, halogen lamps and xenon lamps radiate beat at infrared region. This thermal radiation adversely affects projectors, studio illuminators, and other devices that used these lamps as light sources. A cold mirror solves this problem neatly: it reflects the visible light but passes nearly all of the harmful infrared light through, as indicated in Fig. 29. The non- absorbing multilayer film reflects more than 90% of incident light in the visible region, and transmits more than 80% (average) of the thermal radiation in the near infrared and infrared regions. These mirrors have passed heat and quick- cooling tests as specified by the Japanese Industrial Standards, and have proved superior to rear-silvered, protected mirrors and front aluminized mirrors in tests of resistance to water, acids, alkalis and salt water. 

Max dimensions: concave up to 550mm dia.

Typical spectral characteristics

UV light is reflected efficiently by this mirror of multilayer film and visible and IR are transmitted.

Typical spectral characteristics

A multilayer coating of dielectrics enables a dichroic mirror to reflect a specific wavelength region and transmit other regions. The three standard dichroic mirrors listed below can be combined to separate or combine the three primary colors of white light. Types available are Blue-, Green-, or Red-reflecting mirrors.

Optical specifications

Type : 50% T (nm)

Blue-reflecting mirror: 490±10

Green-reflecting mirror: 500±10, 580±10

Red-reflecting mirror: 590±10

Typical spectral characteristics

This is a transparent heat reflecting conductive coating that efficiently reflects thermal energy from a heat source. 

This dichroic mirror reflects red, green blue and yellow colors by utilizing halogen lamp. The heat resistance and moisture resistance are excellent. Due to its efficient colour rendering properties this is suitable for lighting applications. 

These are mirrors for UV, visible and Infrared region and consist of metallic films such as aluminium, silver, chromel, and gold. 

This filter has characteristics of low insertion loss, good flatness at the pass band and high isolation due to steep separation properties. The filter is used for separation of the signal of 1.55um from the pump laser of 1.48um and the monitoring signal of 1.51um. Custom design of incident angle and wavelength is available. 

Mirror substrates and other optical elements for laser applications can be fabricated on request.
