Astronomy

NDC Optics understands the strict requirements of terrestrial & space-based optical filter applications. We have filters installed in the world’s largest & most recent scientific telescope systems.
 
Applications include steep-profiled Narrowband Filters and Spectrograph Sorting Filters, designed to operate in cryostat conditions, or in space environments.
 
Custom design and analytical testing are vital in astronomical & Space applications. We routinely support astronomical projects with detailed design analysis to predict filter performance in specific situations, including the effects of cone angle or cooling to operating temperatures.
 
We maintain calibrated Dual-Beam & FT-IR spectrophotometer facilities, to assure the wavelength accuracy of our most precise filters.
 
Space Environment Qualification and Calibration of cooling effects on our filters is well-established. Astronomical filters are typically supplied with data to characterize spectral shift & transmission level changes across the operating temperature range. These features can be measured directly on samples from the individual manufacturing batches.
