Optical Bandpass Filters

Andover Corporation offers a standard selection of gas analysis filters at popular wavelengths from 2.7µm to 10.6µm. We can also produce custom filters at wavelengths up to 14µm. In the infrared region of the spectrum, bandpass filters are frequently used for gas analysis applications. Read more...

Andover Advantage: Semi-Custom Optical Filters Ultra-narrow bandwidths narrow as 0.15nm / Broad-band widths (wide as 100nm) Read more...

Rapid Spectral Solutions (RSS) has a listing of many bandpass filters with FWHM of 1.0 to 50 nm, with a feature of accepting light from a substantial field of view. Filters can be provided Read more...

Andover's first-surface, hard-coat narrowband filters employ magnetron sputtered, hard-oxide coatings deposited on Borosilicate Glass, suitable for high temperature applications. They provide a steep transition from a high, peak transmission to OD4 blocking. Available at wavelengths from 334nm to 1550nm, including all major laser lines and atomic absorption lines.

In order to make it simple for customers to custom-tailor a bandpass filter for their application, Andover offers a line of Semi-Custom bandpass filters. We offer a wide selection of wavelengths, bandwidths, and sizes, and offer two blocking options. Read more...

Our first-surface, hard-coat narrowband filters employ magnetron sputtered, hard-oxide coatings deposited on Borosilicate Glass and do not utilize any absorbing filter glasses, making them suitable for high-temperature applications. They provide a steep transition from a high, peak transmission to OD4 blocking. Read more...

There are a number of variations of an optical bandpass filter’s construction, and each has its advantages. Andover offers a variety of options so that you can select the best-suited filter type for your application. Read more...

Sub-Nanometer Bandpass Filters with OD 4 Free Spectral Range

Sub-Nanometer Bandpass Filters with OD 4 Free Spectral Range. Rapid Spectral Solutions (RSS) has a listing of many atomic and laser emission line filters with FWHM of less than 1.0 nm. Getting them in your hands in days to weeks rather than months, for the lowest possible cost, is a challenge we thrive on. Read more...
