Surplus - IR Bandpass Filters

Surplus IR Bandpass Filters from Andover Corporation offer exceptional value on premium infrared optical filters at reduced prices.

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.
