STANDARD IR BANDPASS FILTERS

In the infrared region of the spectrum, bandpass filters are frequently used for gas analysis applications. Andover offers a standard selection of gas analysis filters at popular wavelengths. We can also produce custom filters at wavelengths up to 14µm. Constructed of hard, durable first-surface dielectric coatings on optical-quality IR-transmitting substrates, these filters will withstand normal cleaning and handling associated with any high-quality optical component. 

For your convenience and economy, we offer the filters in 25mm dia. However, we can produce custom sizes and shapes, as well as custom optical characteristics. Contact our technical sales department for a quotation.
