Rack Type Wavelength Tunable Filter Unit

Wavelength can be tuned by changing the angle of an oxide dielectric bandpass filter. This module rotates oxide dielectric bandpass filters with a micrometer to control wavelength. This product combines the modules as units. A 3U rack can contain up to 8 units.

- Capability to tune wavelength of multi-cavity bandpass filters
- Exchangeable holder type filters
- Filter holder with capability for common use with rack type and cartridge type
- All units (polarization controllers, optical delay lines, etc.) are exchangeable and can be arbitrarily combined within a rack.
