Optical Filters Products

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

    These LiDAR laser sensor systems feature 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.

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

    In astronomical observations, optical filters 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. Glass Machining 12/8/2015

    Abrisa Technologies provides multiple technologies/processes to support your glass/optics shapes, surfaces, edging, and hole drilling requirements. Depending on glass types, thicknesses, hole diameter, and edge quality; Abrisa Technologies can choose between CNC machining, opposed edge drilling, or abrasive material removal or sandblasting to meet your specific glass fabrication requirements.

  5. 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.

  6. 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.

  7. 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.

  8. Windows, Mirrors, and Color Filter Glass 6/29/2014

    Ross Optical offers a variety of precision and standard windows, sapphire windows, round, square, and elliptical mirrors, and long pass, band pass, neutral density, and heat absorbing filters. This page provides an overview of these offerings.

  9. Raman Filters 12/13/2013

    These Raman filters offer a low loss and flat transmittance rate, high environmental stability, steep pass-block transition, OD5 to OD6 blocking, and long-term shift-free spectral performance. Wide flexibility in filter size is available, making them ideal for compact optical setups.

  10. SWIR Bandpass Filters 12/13/2013

    Optics Balzers’ SWIR bandpass filters feature excellent environmental stability, high transmittance in the passband, a self-blocking design with a blocking range over the full detector response,  and long-term shift-free spectral performance.
