IR Filters
Infrared (IR) filters are sophisticated optical components engineered to precisely control and manipulate radiation across the infrared spectrum, from near-IR (1.05μm) through far-IR (30μm). These specialized filters enable selective transmission of specific infrared wavelengths while providing exceptional blocking of unwanted radiation - essential capabilities for applications in thermal imaging, spectroscopy, and defense systems.
Andover Corporation manufactures IR filters using multiple advanced technologies, including hard oxide coatings, multi-cavity designs, and diamond-like carbon (DLC) coatings on premium IR-transmitting substrates. Our comprehensive portfolio includes bandpass filters with bandwidths from 1% to 50% of center wavelength, sharp-transition long wave pass filters, and specialized IR neutral density solutions. Whether you need standard components or custom designs optimized for your specific requirements, our vertically integrated facility ensures consistent quality and precise spectral control across the entire infrared spectrum.
