Surplus - Edge Filters

Surplus Edge Filters from Andover Corporation provide exceptional value on high-quality long-wave pass and short-wave pass filters at reduced prices. These optical components offer well-defined transitions between reflecting and transmitting regions, making them ideal for wavelength isolation applications.

Each surplus edge filter features the same durable, first-surface dielectric coatings and precise optical specifications as our standard product line, but at significant savings. These filters utilize interference effects rather than absorption to isolate spectral bands, providing steeper transitions than comparable colored glass alternatives. Our surplus inventory includes various cut-on and cut-off wavelengths across the UV, visible, and NIR spectrum, perfect for researchers, educational institutions, and companies seeking cost-effective solutions for fluorescence applications, photometry, and spectral management. Despite being offered at discounted prices, these filters maintain excellent optical quality and performance. Inventory changes regularly, so we recommend checking our listings frequently for the best selection.
