Dual Band Infrared Bandpass Filters
Description
Reynard dual-band infrared (IR) bandpass optical filters provide high in-band transmission in both the MWIR (mid-wave, 3-5μm range) and the LWIR (long-wave, 7.5-13.5μm range) simultaneously, while providing high out-of-band (OOB) rejection.
In-band transmission levels above 90% have been demonstrated on multiple substrate materials with different wavelength and transmission performance requirements.
MIL-STD environmental testing has verified excellent durability and stable spectral performance. Direct spectral measurement at 80K (LN2) demonstrates cryogenic temperature durability and minimal wavelength shift from ambient conditions (dx/dT).
Optical coatings can be applied to small or large substrates with plano or curved surfaces, all with excellent part-to-part and edge-to-edge uniformity.
Dual-Band Infrared Bandpass optical filter coatings are ideal for current and next-generation infrared imaging systems that require high-performance in-band and out-of-band blocking in multiple wavelength bands.
Reynard can customize any dual-band infrared bandpass optical filter to meet the performance needs of your system. All manufacturing is done in-house for improved quality, ease of communication and innovative customization.
