Dual Band Infrared Bandpass Filters
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 ...

25.4 mm Absorptive ND Filter Optical Density - 0.1
This series of absorbing glass neutral density filters is offered in small increments from D=0.1 up to D=4. The thickness of the filters is controlled to produce a calibrated optical density at 546 nm. The response is approximately neutral so they can be used as broad band devices. However, if used at other wavelengths the optical ...
