Iridian Spectral Technologies designs and manufactures optical filters that are optimized for flow cytometry applications. These dichroic (FLD) and emission (FLE) filters deliver more signals with less background noise, and are compatible with common excitation sources and fluorophores. They also feature high transmission and reflection levels, low ripple, steep edges, and deep blocking outside of the pass band.

Iridian Spectral Technologies has designed and manufactured a wide range of dielectric optical filters for imaging and machine vision applications. Featuring steep edges, high transmission values, and high durability, these color filters can be used to improve contrasts, and isolate spectral regions and colors in images.

Iridian Spectral offers edge, notch, and band pass optical filters covering the 300nm (UV) to 10µm (LWIR) wavelength range for biomedical instrumentation, and medical devices for endoscopy and laparoscopy.

Iridian offers excitation, dichroic, and emission fluorescence spectroscopy filters for confocal microscopy, flow cytometry, and other biomedical applications. These three different filter types are often used in a set in order to maximize the desired signal while minimizing the undesired signal.

The popularity of 3D cinema has grown in the last five years, and in that time, Iridian Spectral Technologies has manufactured millions of reusable 3D color band glasses for 3D cinema. They’re durable, scratch-resistant, and even dishwasher safe for sterilization and reuse.

Iridian Spectral Technologies has developed oleophobic and hydrophobic AF coatings for easy cleaning and smudge resistance, and AR coatings to suppress surface reflections for use in touch-screen technology in vehicle interiors.

In Raman spectroscopy applications, emitted light is very close in wavelength range to the excitation light. In order to attenuate a laser’s signal from reaching the detector while at the same time transmitting the weak emitted light signal, notch or edge pass Raman filters are required. Because of their high transmittance and extended deep blocking, Raman laser line filters are also required to ensure that only the desired wavelength is actually illuminating the sample being tested. This page provides an overview of Iridian Spectral Technologies' line of filters for Raman spectroscopy.

Iridian Spectral Technologies ships anywhere between 10,000 to 40,000 telecom filters per week. These filters are used in a wide variety of telecom applications, including wavelength multiplexing and de-multiplexing,  optical amplification/gain flattening, laser wavelength stabilization, pulse dispersion compensation, fiber-to-the home/business, and fiber line monitoring. More details on the applications can be found below.

Iridian Spectral Technologies' multi-zone filters offer spatially varying spectral performance on a single substrate in the UV to LWIR wavelength range. Filter types include bandpass, notch, long-pass, and short-pass with coatings offered for AR, high-reflectivity, and black-absorbing.

Iridian Spectral Technologies offers filters and coatings for satellites and LEO instrumentation, including large format filters for astronomical observations (single band and multi-band pass filters), light absorbers/black coatings, dichroic mirrors and beam-splitters, and multi-element arrays.

Iridian Spectral Technologies' MLWIR (mid-long wave infrared) bandpass filters provide narrow and high transmission in the 2-10µm wavelength region, ultimately enabling an optical systems’ ability to detect a gas and its concentration in environmental and process analysis.

In 2016, the FAA estimated a total of 8681 incidents where pilots were subjected to distractions, or in some extreme cases temporary blindness, by commercially available laser pointers. To combat this, Iridian Spectral Technologies developed LaseReflect aviator glasses to protect pilots from visible laser attacks.

Iridian has recently added new coating systems and processing equipment to significantly expand our capacity and capability to continue to provide technically and commercially leading optical filters to our customers.

Iridian has recently announced that they have successfully completed their certification audit to the ISO9001:2015 standard. 

Iridian is now able to offer its high performance LaseReflect^® Aviator LRG13 glasses for a new low price as a result of ongoing technology development and improvement to out production processes.

Iridian announced its new reduced prices for its standard filters by 8-49% due to improvements in optical filter manufacturing processes and efficiencies.

The desire to accurately identify, measure, and monitor environmental and process gases in fields as diverse as agriculture, automotive, medicine, and petrochemicals has driven increased demands for Photoacoustic Spectroscopy (PAS).

Iridian’s Dual Pass Band Filter features two pass bands in one filter chip. This filter allows for modern CWDM designs that reduce the number of required filters, minimize insertion loss and allow smaller packaging.

Iridian Spectral Technologies delivers fluorescence emission filters, excitation filters, fluorescence filter sets, and fluorescence multi-band filters for fluorescence analysis instruments, fluorescence imaging instruments and fluorescence microscopes. The available emission, excitation and dichroic filters provide more signal, less background noise, high transmission and reflection levels, low ripple, steep edges, and deep block to fluorescence instrument users and OEMs.

Iridian Spectral Technologies delivers an array of optical filter solutions, including bandpass filters, edge pass filters, and dichroic filters for Raman spectroscopic applications. Iridian also offers partnership opportunities to develop custom filter solutions.

Iridian Spectral Technologies offers optical filter solutions to address the growing needs for Datacom optical filtering applications. These Datacom filter solutions can now address needs like wavelength division multiplexing (WDM) in transceivers, broad bandpass filters transmitting the entire O, C, or L-band, and silicon (Si) etalons for TLA.
