Optical Filters White Papers and Case Studies

51. Using Next-Generation Thin-Film Optical Filters For Fluorescence Imaging And Detection Systems 5/23/2016

    Within any fluorescence application, there are three basic filters that are needed for operation – the excitation filter, the emission filter, and the beamsplitter. This white paper further discusses the use of Alluxa’s thin-film optical filters in fluorescence imaging and detection systems.

52. Enhancing Endoscopy With Optical Filters 10/30/2015

    While white-light reflectance (WLR) imaging has become the standard for in vivo diagnosis using “conventional endoscopy,” this white paper details three alternatives — or supplements — to WLR that leverage the wavelength selectivity provided by optical filters.

53. BOROFLOAT & Optical Mirrors: A Union of Inspiration & Quality 6/19/2015

    This white paper introduces BOROFLOAT, the world’s first borosilicate glass by SCHOTT, explains how it is used in the Hobby Eberly Telescope (HET) and describes its exceptional optical and thermal properties.

54. Clear The Air: New Optical Filters For Sensors And Detectors 4/2/2015

    Our world is increasingly monitored with sensors and detectors measuring things like air quality and IoT. Discover how this technology helps us better understand and interact with our environment.

55. Metal-Mesh Optical Filter Technology for Mid-IR, Far-IR, Terahertz and Submillimeter Ranges 7/6/2012

    Metal-mesh filters are used to selectively filter far-infrared radiation before it reaches a detector. Metal mesh filters improve detection capabilities through blocking out-of-band interferences, can improve the performance of lower-end detectors, improve signal-to-noise ratio (SNR), and much more. They are ideal for increasing system performance for astronomical spectroscopy and space-based applications. This article discusses the benefit over using metal-mesh filters in the mid-to-far infrared spectral range over multilayer thin film dielectric filters, and band pass filters.
