Angle Tunable Type Wavelength Tunable Filter Module

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.

Features
- Capability to tune wavelength of multi-cavity bandpass filters
- Includes a chart of micro characteristics (refer to the photo)
- Exchangeable holder type filters
- Rack type filter holder with capability for common use with cartridge type
