  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

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

    A dichroic filter, thin-film filter, or interference filter is a very accurate color filter used to selectively pass light of a small range of colors while reflecting other colors. By comparison, 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.

  7. What Is A Neutral Density Filter? 11/21/2019

    A neutral density, or ND, optical filter reduces or modifies the intensity of all wavelengths or colors of light equally, therefore providing for no changes in the hue of the color rendition. Neutral density filters can be colorless or clear, or they can be grey in tone.

  8. How To Measure Thin, Parallel Optics 10/1/2019

    Thin, parallel optics are difficult to measure, because both front and back surfaces reflect light. Fourier- Transform Phase Shifting Interferometry can separate those reflections and provide more information than traditional methods. 

  9. Remote Sensing With LiDAR Requires Optical Filter Trade-Offs 4/12/2019

    Engineers and designers working on LiDAR applications should consider critical filter issues early on.

  10. LiDAR And Optical Filters – Helping Autonomous Vehicles See More Clearly 10/31/2018

    The evolution of sensing and imaging systems, combined with the desire to create safer, more efficient transportation systems, is driving the development of autonomous vehicles. LiDAR is a key technology that will eventually help carry this growth through to “Level 5” autonomy.
