Bandpass Filters
Bandpass filters deliver precision wavelength control by transmitting specific bands of light while blocking unwanted wavelengths. The ability to isolate exact portions of the spectrum makes these filters indispensable for demanding applications in microscopy, astronomy, environmental monitoring, and defense systems, where reliable and precise light control is essential.
Andover Corporation's bandpass filters deliver precision wavelength selection from UV to IR through innovative optical design. These filters act as selective gates, transmitting specific wavelength bands while blocking unwanted light. Available in multiple constructions including all-dielectric and metal-dielectric types, our filters serve applications from standard industrial uses to specialized research requirements.
Our comprehensive range includes standard bandpass filters with proven 10-20 year field lifetime, semi-custom options with quick turnaround times, and hard-coated variants for demanding environments. Select from bandwidths as narrow as 0.15nm up to 300nm, with center wavelengths spanning 193nm to 14μm. Whether you need a few specialized filters or high-volume production runs, our vertically integrated facility ensures consistent quality and reliable delivery.
