IR Filters

Dielectric bandpass filters according to customer specifications. The infrared filters are available in the wavelength range from 1.0 µm to 20.0 µm.

Dielectric coatings. Customer-specific solutions are also available for IR long-pass filters.

Si, Ge, or InAs wafers with an AR coating. IR semiconductor filters function as long-pass filters with very good blocking.

Neutral density filters for the IR range from 1.5 µm – 14.0 µm. Neutral gray filters are used in attenuation.
