Surplus - IR Bandpass Filters
Surplus - IR Bandpass Filters
Surplus IR Bandpass Filters from Andover Corporation offer exceptional value on premium infrared optical filters at reduced prices. These specialized filters isolate specific regions of the infrared spectrum while providing 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, these surplus filters maintain the same exacting standards as our regular product line. Available in a range of center wavelengths and bandwidths, they're ideal for researchers, educational institutions, and companies seeking cost-effective solutions for environmental monitoring, security systems, thermal imaging, and specialized infrared applications. Despite being offered at discounted prices, these filters deliver excellent optical performance and durability, capable of withstanding normal cleaning and handling required of high-quality optical components. Inventory changes regularly based on availability, so we recommend checking our listings frequently for the best selection.
