IR Filters

IR filters have often been difficult for many users to find reasonably priced. Janos offers a standard line of IR filters that will meet most common requirements, priced to allow the small volume user the economies of scale that historically were only available to high volume users. Our selection is based on the bandpass lines most frequently requested by our customers.

Janos infrared filters are thin-film designs on solid substrates of crown glass, fused silica, sapphire, or germanium, depending on wavelength of the filter. The filters are one inch in diameter, and are offered in a variety of bandpass, longpass, and shortpass configurations.

Customers desiring configurations different than those offered in our standard line please feel free to contact us on IR filters.
