At the "Photonics-2024" exhibition, the "Roselectronica" holding showed the general public its new line of optical infrared filters for thermal imagers, guidance systems, civil video equipment and fiber-optic instrument engineering "Amethyst-IR". The filters became known at the beginning of the year, but it was only now that it became possible to see them clearly.
"Amethyst-IR" are short-wave and long-wave blocking, narrow-band and bandpass filters. They are:
- easily mounted on any lens;
- provide images from 2 μm to 20 μm and shooting in twilight, fog and other conditions of poor visibility;
- retain working properties for 15 years;
- can be operated at temperatures from -60 to 70 degrees Celsius and relative humidity of 98%.
According to information from the "Rostec" subsidiary, "Amethysts" will replace the Swedish, American and English filters that are currently in use. In particular, products from Swedish Spectrogon, British Andover, and American Edmund Optics.
The "Amethyst-IR" line of interference infrared filters was developed and is manufactured by the St. Petersburg Research Institute "Giricond", which is part of "Roselectronica".
