Surplus - Hard-Coated Bandpass Filters

Surplus Hard-Coated Bandpass Filters from Andover Corporation offer exceptional value on premium optical filters at reduced prices. These specialized filters feature plasma-deposited, hard-oxide coatings on borosilicate glass substrates, making them remarkably durable and suitable for high-temperature applications.

Unlike conventional soft-coated filters, these hard-coated variants contain no absorbing filter glasses, allowing them to withstand demanding environmental conditions while maintaining optical performance. Each surplus filter provides a steep transition from high peak transmission to deep OD4 blocking, effectively isolating specific wavelength bands while rejecting unwanted radiation. Available across various wavelengths including major laser lines and atomic absorption bands, these surplus items represent significant savings without compromising on quality. Ideal for machine vision, biotech instrumentation, medical devices, and other precision optical applications, these filters deliver professional performance at a fraction of the standard cost. Inventory changes regularly, so we recommend checking our listings frequently for the best selection.
