Irix 300SR

Designed for the Polish Earth observation nanosatellite Swiatowid.

The Irix 300SR is the first Irix telescopic lens designed especially for nanosatellites observing the Earth. This lens project is a response to the rapidly growing space market’s demand for top-class optics for small observation satellites.

Thanks to close cooperation with the Polish company SatRevoution, the first experimental prototype of this lens was the main optical section of the Swiatowid nanosatellite, delivered to an ISS on April 19, 2019 and deployed to LEO on July 3, 2019. Mission ended March 14, 2021.

The telescope

The 300SR telescopic 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 telescope.

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.

Laboratory tests

Thanks to the use of innovative technologies and modular optical system, the lens may be used on satellites equipped with an image sensor resolution up to 35 megapixels and up to 30 mm diameter. Laboratory simulations have shown that the Irix 300SR is be able to provide high resolution images of the Earth’s surface.

High-resolution Earth imagery

The role of Irix 300SR was to provide high quality image for the satellite’s camera which was equipped with a 5.1 megapixel 2/3″ CMOS sensor. The Earth photographs taken with a GSD 4.7m resolution can be used in the future in such projects as: Urban Planning, Land Surveying, Smart Cities and Natural Disasters Monitoring.

Designed to be tough

Spacecraft and equipment operating in outer space must be always verified in terms of safety of the space mission. They are subject of rigorous test procedures developed by NASA. Tests include resistance to strong g-forces and any mechanical and acoustic vibrations that occur during the launch of the rocket. Additional tests also check resistance to extreme temperatures, strong radiation and the ultra-high vacuum of outer space.
