High performance infrared bandpass filters will be produced through enhanced technology including, improved spectral measurement devices of filters and calibration samples, improved software for extracting optical constants from deposited thin films, improved deposition thickness monitoring devices, and computer integration of the deposition process. This proposed work will submit coatings on substrates with specially designed antireflection coatings on the back sides which demonstrate the capability of producing high performance infrared bandpass filters. Multiple samples will be delivered out of separate deposition runs to demonstrate process repeatability. Spectra resolution measurements will be made on all filters as well as some environmental durability tests.
