Purpose:
- filtration of optical radiation;
- suppression of powerful laser radiation in order to protect photodetectors and eyes from glare and damage.

Technologies used:
- technology of holographic production;
- technology of application and processing of photosensitive layers of bichromated gelatin;
- means and methods of control of optical characteristics.

Benefits:
- high radiation resistance;
- narrow band of suppression with sharp boundaries;
- high transmission beyond the band of suppression;
- high optical density in the suppression band;
- the possibility of smooth adjustment of the position of the suppression band in a small wavelength interval;
- High resistance to mechanical and climatic influences.
