Frequently Asked Questions
Dual-band optical filters transmit light in two discrete wavelength bands while rejecting all others. They are essential when multiple spectral signals must be detected or processed simultaneously, such as combining a visible pilot laser with an infrared designator in targeting systems or capturing separate fluorescence channels in microscopy and multispectral imaging.
Andover’s dual-band filters are custom-designed and can span a wide range from the ultraviolet through the infrared, including common combinations like 1064nm and 1550nm.
Yes. Andover specializes in custom dual-band filter design, tailoring transmission profiles, bandwidths, blocking levels, and physical formats to meet your application needs.
Applications include laser range finding, targeting systems, remote sensing, and optical communications—especially where eye-safe and tactical laser wavelengths are used together.
