Transmittive Filters

Transmission Filters

The transmission filter is designed for laser wavelength control and tuning.
The etalon provides a large free spectral range in combination with a low insertion loss. A fine tuning of the wavelength can be realized by changing the angle of incidence (AOI).

We provide unmounted transmission filters with a standard substrate thickness of 450 µm.

Available chip areas:

5.0 mm x 5.0 mm
4.0 mm x 4.0 mm
2.0 mm x 2.0 mm
custom dimensions on request
1/2" or 1" copper heat sink for 5.0 mm x 5.0 mm filters
