  1. New Tool Measures 4 Surface Appearance Quality Conditions Simultaneously
    1/18/2018

    If surface appearance quality is critical to your product, learn about a new manufacturing-friendly tool that allows you to establish numerical standards for and measure four conditions of surface quality: gloss, haze, image clarity, and BRDF including Canon’s new parameter “Scattering C20, C60.” This new parameter goes beyond IC and DOI to enable measure of non-glossy surfaces such as textured surfaces, matte paint, and matte paper. 

  2. “Dynamic” Deadfront Interface Panel Glass
    10/24/2016

    A “dynamic” deadfront panel is used to create a sleek, uncluttered user interface appearance, drawing attention to the “hidden” light up indicators as required. The icons or other alpha-numeric indicators are visible when backlit, and when unlit, a monochromatic streamlined look is achieved. Abrisa Technologies offers complete solutions for deadfront panel glass technologies including screen printed graphics, chemical strengthening or heat tempering, anti-scratch coatings, and more.

  3. How To Select A Spherical Lens
    7/6/2016

    Optical systems use lenses to focus, collimate, expand, collect, and image light. Ranging from convex to concave, and bestform to aspheric, any lens selection must be made with the utmost consideration for its purpose as well as its required quality. This white paper delivers a review of singlet spherical lens shapes, and guidance on deciding the best lens characteristics for each application.

  4. Specifying Optical Filters for Sensor Applications
    7/1/2016

    Each sensor application has its own subtleties that need to be addressed in order to choose the appropriate optical filters for each sensing task. This application note discusses the critical parameters for bandpass filters that are to be used for sensor applications, including considerations on in-band transmission, band edge placement, and out-of-band blocking.

  6. Technical Note: Guide To Glass
    6/30/2016

    Guide to Glass provides information about the types of glass and their associated thermal, optical, chemical, mechanical, and electrical properties; Understanding light & color; glare reduction; and glass Strengthening methods using heat and chemicals.

  7. Semi-Transparent Mirrors For Visually Dynamic Hospitality Displays
    5/23/2016

    Hotel, restaurant, and retail owners are increasingly using aesthetically pleasing high-performance semi-transparent mirrors to create a visually dynamic display/mirror combination. These mirrors are constructed with a display unit hidden behind the glass that is not visible until powered on. 

  8. Specifying Wavefront Or Surface Error In Aspheres
    5/12/2016

    The optical quality of aspheric mirrors is commonly specified by their surface accuracy and reflected wavefront error. The surface error is the deviation of the surface from its perfect form, while the wavefront error is the deviation of the resulting reflected or transmitted wavefront from its perfect shape. It is often assumed that these tolerances are related to each other by a simple scale factor. However, that is not the case when it comes to aspheric mirrors. This application note compares surface accuracy measurements with wavefront error measurements, and provides an application example on using them in off-axis parabolas.

  9. Benefits Of Heat Tempering vs. Heat Strengthening Of Glass
    4/12/2016

    There are two types of heat-treated glass. Heat-strengthened glass is approximately two times stronger than annealed or untreated glass, while the tempered glass will be four times stronger and less likely to experience breakage through thermal shock. This application note presents the benefits and characteristics of each type of heat-treated glass.
