Surplus - IR Edge Filters

Surplus IR Edge Filters from Andover Corporation offer exceptional value on premium infrared long-wave pass and short-wave pass filters at reduced prices. These specialized components provide sharp cut-off transitions in the infrared spectrum, effectively isolating broad spectral regions while delivering high transmission of desired energy and deep rejection of unwanted radiation.

Constructed with hard, durable first-surface dielectric coatings on optical-quality IR-transmitting substrates such as germanium, silicon, and other infrared materials, these surplus filters maintain the same rigorous quality standards as our regular product line. They're ideal for researchers, educational institutions, and companies seeking cost-effective solutions for order sorting in FTIR spectroscopy, thermal imaging, and specialized infrared applications. Despite being offered at discounted prices, these filters provide excellent optical performance and durability, capable of withstanding normal cleaning and handling. Inventory changes regularly based on availability, so we recommend checking our listings frequently for the best selection.
