Surplus - Bandpass Filters

Surplus Bandpass Filters from Andover Corporation offer exceptional value on high-quality optical filters at reduced prices. These surplus items include standard, high-transmitting, and specialized bandpass filters that isolate specific wavelength regions while rejecting unwanted radiation.

Each surplus bandpass filter is manufactured to the same rigorous quality standards as our regular product line, featuring precisely controlled center wavelengths and bandwidths. Despite being offered at discounted prices, these filters maintain excellent optical performance, stability, and durability. Our surplus inventory includes filters across the spectrum from ultraviolet through visible to infrared wavelengths, making them ideal for researchers, educational institutions, and companies seeking cost-effective solutions for spectroscopy, fluorescence applications, imaging systems, and other optical setups. Inventory changes regularly based on availability, so we recommend checking our listings frequently for the best selection of wavelengths and specifications.
