IEC 63032:2018 applies to the family of tuneable bandpass filters. These components can modify the spectral intensity distribution in order to select some wavelengths and inhibit others.
They can be categorized into the following:
- wavelength tuneable,
- bandwidth tuneable,
- wavelength and bandwidth tuneable filter.
This document establishes uniform requirements for optical, mechanical and environmental properties.
