Optical Filters Products

  1. Optical Filters For LiDAR Laser Sensors
    9/5/2019

    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.

  2. Space And Specialty Optical Filters For Earth Observation
    9/5/2019

    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.

  3. Satcom Optical Filters And Coatings
    9/5/2019

    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.

  4. Imaging Color Filters

With CNC processing and other glass fabrication equipment, this company can manufacture a wide variety of glass parts ranging from simple to the most complex designs. Some of the offered processes performed in-house include notching, slotting, grooving, edge grinding, stepped surfaces, hole drilling, circle grinding, polishing, and sandblasting.

  8. Optical Filters
    12/27/2014

    Acton Optics & Coatings offers bandpass, band rejection, long pass, neutral density, reflective, and solar blind filters for spectroscopy, elemental analysis, environmental monitoring, biotechnology instrumentation, space exploration, and in general research areas.

  9. Fluorescence Filters
    8/7/2014

    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.

  10. Raman Filters
    7/22/2014

    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.
