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.
