PHILTEC Sensors Perform on Satellites in Space
It’s not often we discover how well PHILTEC sensors perform for customers. The Euclid Satellite project is a good example of their sensors functioning with excellent results in cryogenic conditions on satellites in space.
A technical paper published in 2012 describes how PHILTEC’s high precision sensors work at 150°K to verify the distortion of lens holders to be <1 micron, well within the project requirements.

The complete description of PHILTEC sensor installation and calibrations at cryogenic temperatures are found in ‘Section 4 Metrology’.
This work verifies the accuracy of the Euclid Space Telescope Lenses. Euclid is a space telescope currently under development by the European Space Agency and the Euclid Consortium. Launch date scheduled for 2022.
