Światowid

Irix 300 SR. The first space ready Irix lens.

Światowid

Designed for the Polish Earth observation nanosatellite Swiatowid

The 300SR lens is designed with cooperation of the European Irix R&D Centre located in Krakow (Poland), which deals with research for the innovative materials and solutions to be used in the future Irix space ready lens.

The lens is made entirely based on NASA guidelines for spacecraft and their payloads. These guidelines relate to materials and technologies that have been laboratory-tested and experimentally verified during space missions.
