Infrared Filters

Infrared filters can be designed in bandpass, longpass, and shortpass configurations for applications in the SWIR, NIR, and MIR wavelength bands. Examples of bandpass filters in the NIR and MIR are shown below. Low stress coatings with high blocking in the visible are afforded by incorporating high index semiconductors in the designs.



Omega fabricates infrared filters with both dielectric and semiconducting materials. Substrates can be silicon, zinc selenide, or various glasses depending on the specified wavelength.
