High Peak Transmission
Reynard Corporation’s bandpass infrared filters (multi-band & single-band) provide high in-band transmission in both MWIR (mid-wave, 3-5µm range) and the LWIR (long-wave, 7.5-13.5µm range) simultaneously, while providing high out-of-band rejection. In-band transmission levels above 90% have been demonstrated on multiple substrate materials with different wavelength and transmission performance requirements.
Custom multi-band and single-band bandpass filter prototypes to volume production are available.
