Case Study: Optical Components for Targeting Pods
This case study looks at the role of optical components in targeting pods – for real-time data, enhancing the ability to acquire, track and engage targets effectively.
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
Case Study – Measuring Space Optics and Structures
An overview of the techniques and configurations used to build dynamic interferometers and measurement results for a variety of space-based optical components. From our optical metrology partners,
