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.

Teraxion makes high-precision optical filters for ASE and Brillouin filtering in sensing applications or for the isolation of a modulated RF signal in RF communications. Signal isolation filters exhibit unbeatable flat top steep edge specifications. Low dispersion filters are also available for picosecond laser spectral filtering.

UltraFast Innovations (UFI) offers 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 in time, resulting in the generation of sub-optical-cycle pulses. Based on that technology, we also offer the first commercial light field synthesizer.

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).

The IXC-FBG-PS bandpass filter has a sharp resonance peak in the transmission spectrum with less than 1 dB of insertion loss. It can be used in telecom as well as in sensing applications, also for distributed feedback (DFB) fiber lasers.

iXblue offers a broad range of Fiber Bragg Gratings (FBG) to address a wide array of applications in telecommunications, sensing, harsh environments, research and development, etc.

The excellent know-how in the FBG manufacturing process gives iXblue the capability to produce various filters on a variety of in house fibers. We stand ready to adapt our services to your needs from quick prototyping to volume production.

OPTOMAN optical filter coating designs are available in short pass, long pass or bandpass configurations. Our IBS-coated optics are optimized for high power applications and feature spectral drift-free performance, which is why very sharp edge configurations are feasible.

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.
