IR Filters

IR Long-pass Filters

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

IR Bandpass 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.

IR Neutral Density Filters

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

Infrared Semiconductor Filters

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