Where to Buy Optical Filters

Crystalline material UV band pass filters, neutral density reflective type filters designed to operate at 400–2000 nm range, neutral density absorption type filters designed to operate at VIS (450–650 nm) and Schott color glass filters.

Iridian Spectral Technologies is a leading global supplier for applications in telecommunications, spectroscopy (Raman, fluorescence, and flow cytometry), biomedical imaging, endoscopy imaging, sensing, display and entertainment (glasses for 3D cinema, display coatings). Our optical filters and coatings cover the spectral range from UV 300 nm to LWIR 10 μm. Our products include narrow bandpass filters, steep edge long- or shortpass filters, dichroic edge filter, notch filter, multi-zone filter and other special coating filters.

Ultra narrow tunable optical filters for Brillouin filtering in remote sensing applications or for the isolation of a modulated RF signal in RF communications.

Shanghai Optics manufactures a wide range of custom optical filters for engineering, scientific, and photographic applications.

World leader in Fiber Bragg grating and Fabry Perot filters. Product portfolio includes athermal Fabry–Perot etalons (TWR30) and athermal FBGs (TWR50), as well as tunable FBGs (T10-T980) and tunable Fabry–Perot filters (TFP10-TFP50).

Artifex Engineering offers custom absorption filters and dieletric filters in almost any design. Bandpass, long pass, short pass or ND filters can be tailored to your wavelength range. The filters can be cut to any shape. Black anodized aluminium rings may be provided for ease of mounting. Visit our product page for more information. We look forward to your inquiry.

Edmund Optics offers a variety of optical filters for many applications, including bandpass interference, notch, edge, dichroic, color substrate, or ND. Edmund Optics also offers highly durable hard coatings for applications that require high optical densities with maximum performance.

VisiMax process color filters selectively and accurately pass light of a small range of colors while reflecting other colors. Our heat-resistant dichroic filter coating technology produces durable interference filters that render light with precise spectral control.

Accelerate your project by choosing a standard VisiMax color filter, or utilize the expertise of our skilled design team to create a custom filter to meet your specific spectral requirements.

Our stock and custom-made optical filters are employed for a wide range of high-tech applications by discerning engineers and R&D professionals within sectors such as military & defence, electronics and research markets. With both stock and custom-made filters available, our collection includes bandpass, longpass, shortpass, neutral-density (ND), dichroic, IR-cut, colour glass, heat glass and ANPR/ALPR filters.

Optometrics, a Dynasil company, designs and manufactures long wavepass filters from 500 nm to 1500 nm in increments of 50 nm. These long wavepass filters are mounted in a black anodized aluminium ring. The cut-on wavelengths can be fine tuned by changing the angle of incidence. Optometrics also has short wavepass filters from 450 nm to 1000 nm in increments of 50 nm and otherwise similar characteristics. These filter types can also be used in combination for custom bandpass filtering.

EMF, also a Dynasil company, manufactures a custom line of Optivex™ dichroic filters that block 99% of harmful UV radiation while transmitting high-quality visible light with virtually no distortion. Optivex™ has been the product of choice for over 25 years, and its name is synonymous with absolute protection.
