Optical Filters for Astronomy Applications
Astrophotography uses spectral imaging to measure diverse properties of astronomical objects including molecular composition, ionisation state, redshift, and temperature.
Moxtek in Space: with the James Webb Space Telescope
MOXTEK collaborated with 4D Technology, to develop a wire-grid pixelated polariser for their dynamic laser interferometer which was used to measure the mirrors on NASA’s James Webb Space Telescop
