The RP Photonics Buyer's Guide contains 267 suppliers for optical filters. Among them:
UltraFast Innovations (UFI®) provides spectral filters for ultrashort pulse applications – for example, for preserving the pulse duration of reflected or transmitted pulses.
By using such spectral filters, researchers from Prof. Krausz’s group were able to build a so-called wave synthesizer. We were able to split or combine radiation from 250 to 1100 nm in four channels: 250–290, 290–350, 350–500, and 500–1100 nm. The phases of reflection and transmission are controlled. This allows one to precisely combine radiation from four channels, both spatially and temporally, resulting in the generation of sub-optical-cycle pulses. Based on that technology, we have developed the first commercial light field synthesizer.
Laserton has various types of optical filters, including color class filters, birefringent filters, neutral density filters (absorptive or reflective, also versions with variable transmission) and bandpass interference filters.
LEUKOS offers the widely tunable filter BEBOP. Combine this with our supercontinuum source Rock to obtain a broadband tunable light source.
The BEBOP can be tuned from 350 nm to 850 nm with a bandwidth between 7 nm and 100 nm. It reaches a transmittance of up to 90% and a blocking OD of >4. You can have a free-space output beam or a fiber-coupled output, and there is an additional infrared output.

Ecoptik produces glass filters of different types (absorbing or with thin film coating) for selecting certain radiation bands. We can make many different types and custom optical filters, such as optical comb filters, high/low pass filters and linear variable filters.
EKSMA Optics has introduced OD 6.0 notch filters for specific laser wavelengths in the range from 488 nm to 561 nm. Other filter choices are: neutral density reflective type filters designed to operate in the 400–2000 nm range, neutral density absorption type filters designed to operate at VIS wavelengths (450–650 nm) and Schott color glass filters.
Optical filters selectively allow certain wavelengths of light to pass freely while blocking other wavelengths. Avantier manufactures a wide range of optical filters for engineering, scientific, and photographic applications.
Exail (formerly iXblue)’s gain flattening filter based on fiber Bragg grating technology represents an easy and effective solution to flatten the gain in a WDM systems. The high accuracy (very low ripple) allows the use of cascaded filters, and the return loss is high (low reflections).
