Optical Filters White Papers and Case Studies

  1. Specifying Plasma Deposited Hard-Coated Optical Thin Film Filters 6/18/2020

    Learn about different filter types, their key attributes, and how to optimize cost. The filters discussed include high cavity count band pass, replacement, tilted beamsplitter filters, and more.

  2. Advanced Plasma Deposition Improves Ultra Narrowband Optical Filters 6/18/2020

    Narrowband filters are a critical technology for lidar, laser cleanup, chemical and gas sensing, and more. Because creating multicavity filters is a challenge for deposition process control systems, Alluxa uses a computer-controlled variation on the turning point method of thickness control for each individual layer.

  3. Ultra-Narrowband Optical Bandpass Filters With Large Format And Improved Temperature Stability 6/18/2020

    Hard coated ultra-narrowband optical filters made using modern plasma processes offer much improved transmission, temperature stability and out of band blocking as compared to legacy soft coatings. These filters are used in optical systems as diverse as LIDAR (light detection and ranging), Doppler shift detection of plasma velocity, laser cleanup, chemical and gas sensing, as well as for cutting-edge astronomy and instrumentation applications.

  4. Multiband Filters Redefine Performance Standards Across Disciplines 6/18/2020

    Advances in thin-film technology have led to new classes of multiband filters that redefine performance standards and drive innovation. By understanding their scientific and industrial applications, various filter classes and manufacturing possibilities are also better understood.

  5. Alluxa Introduces HELIX™ Spectral Analysis System For Measuring High-Performance Thin-Film Optical Filters 6/18/2020

    The HELIX Spectral Analysis System has redefined measurement capabilities of high performance thin-film optical filters. HELIX is an instrument designed and developed by Alluxa Engineering staff to address the limitations of most commercially available spectrophotometers.

  6. Thin Film Glossary 6/17/2020

    This article defines a number of glossary terms related to thin film optical filters and their use.

  7. Utilizing Flow Cytometry Filters 6/17/2020

    Used across a variety of biological disciplines, fluorescence-based flow cytometers rapidly and accurately quantify cells and cellular components. As one of the most important components of these systems, flow cytometry filters must be specifically designed to maximize signal-to-noise ratios while minimizing crosstalk between fluorophores.

  8. Utilizing Fluorescence Filters For Microscopy And Imaging 6/17/2020

    Because image quality is highly dependent on the design and overall performance of the fluorescence filters integrated into microscope and imaging systems, optical filter performance is just as important to the final image as sample preparation and fluorophore selection.

  9. Optical Filter Specifications 6/16/2020

    This white paper covers the basics of a number of optical filter specifications.

  10. When Failure Is Not An Option 6/11/2020

    The manufacture of Intelligence, Surveillance, & Reconnaissance (ISR) optics requires a rigorous analysis of the capabilities and methods of an optical component design/manufacturing partner. Not all design/manufacturing partners are the same, and it is important that integrators elect to work in a collaborative way with companies that have the expertise, pedigree and capabilities to scale up production of components in an accurate and repeatable way.
