Iridian offers over 20 years of experience in producing industry leading optical telecommunication and datacom filters for terrestrial systems. Commercial satcom networks will consist of constellations of 100’s to 1000’s of satellites in an interconnected low earth orbit (LEO) mesh. Many of these systems rely on an optical intersatellite link (OISL) architecture to connect satellites via laser based optical communications. Optical filters provide wavelength selectivity to these systems addressing different functional needs from solar rejection windows to beam steering wavelength selective dichroic filters.

Iridian Spectral Technologies offers LiDAR laser sensor systems with common laser wavelengths including 532 nm, 905 nm, 1064 nm, and 1550 nm. These filters provide more signal with less background and are ideal for laser sensor applications, including airborne laser scanning and other methods of capturing 3D data of large areas.

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 designs and manufactures optical filter solutions for long haul and metro access fiber-optic telecom customers. Iridian also applies the same proven thin film filter technology to address the growing needs for Datacom optical filtering providing wavelength selectivity to DCI devices such as transceivers and tunable laser assemblies (TLA).

In astronomical observations, optical filters are able to provide the wavelength selectivity needed to enable telescopes to discriminate signal from background information. These filters often require larger sizes, higher uniformity, and excellent surface quality and surface figure.

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 offers excitation, dichroic, and emission fluorescence spectroscopy filters for confocal microscopy, flow cytometry, and other biomedical 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' 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.

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.
