Optical Filters News

  1. Alluxa's Optical Filters Landed On Mars 3/9/2021

    Alluxa’s optical filters, specially designed for the advanced fluorescence spectrometer on the Mars Perseverance Rover, landed safely on Mars, on February 18, 2021.

  2. Iridian Introduces Standard PCR Filters 12/15/2020

    In an effort to support the rapidly growing use of polymerase chain reaction (PCR) in rapid diagnosis of diseases such as COVID-19, Iridian Spectral Technologies has introduced a line of ultra performance optical filters specifically designed for Real-Time PCR applications. The ultra PCR fluorescence filter sets provide “more signal, with less background” improving the signal to noise ratio for these instruments.  

  3. The Application Of WDM Channel Skip Filters 9/30/2020

    Channel skip filters enable precision band splitting in telecommunications options, offering improved performance over edge pass filters at a cost adaptable to any project budget.

  4. Discover The New Bandpass Filter BP 850-80 HT From Schneider-Kreuznach 9/29/2020

    Schneider-Kreuznach is pleased to present the new BP 850-80 HT infrared filter as an addition to its range of bandpass filters. This filter has been specially developed for applications with powerful infrared high-power LED’s (850nm), which are becoming increasingly popular. Cameras equipped with these LED’s can deliver night-time images up to 20-30 meters. The Schneider-Kreuznach infrared filter in combination with an 850nm LED light source produces strong and shadow-free infrared illumination that is visible to many sensors but invisible to the human eye. Therefore, it is perfectly suitable for the use in surveillance systems and industrial applications.

  5. Advantages Of Multiple Band Pass Filters In Telecommunications Applications 6/19/2020

    Multi band filters help optimize price-performance balance while also conserving space, simplifying design, and improving (or offering equivalent) performance versus single band filters.

  6. What Are Thin-Film Optical Filters? 6/16/2020

    Thin-film optical filters are made by depositing alternating thin layers of materials with special optical properties onto a substrate, such as optical-grade glass. As light makes its way through the optical filter, its direction changes as it passes from one layer to the next, resulting in internal interference.

  7. Fiber Optics Can Do That? 5/26/2020

    Rigid and flexible fiber optic image guides offer a powerful way to manipulate image planes and achieve remote viewing.

  8. Hybrid Gain Flattening Filters In Optical Fiber Amplifiers 2/18/2020

    Hybrid GFFs save space, simplify system layouts, cost less than a two-filter setup, and offer unparalleled reliability. Meet the new standard in optical fiber amplifier components.

  9. What Is A UV Filter? 11/21/2019

    A UV-blocking filter or ultraviolet optical filter prevents ultraviolet light transmission. UV filters are commonly used in photography to reduce the level of ultraviolet light that strikes the recording medium.

  10. What Is A Dichroic Filter? 11/21/2019

    A dichroic filter, thin-film filter, or interference filter, is a color filter used to selectively pass light of a small range of colors while reflecting other colors. Dichroic mirrors and dichroic reflectors tend to be characterized by the color(s) of light that they reflect, rather than the color(s) they pass.
