Mirrors White Papers and Case Studies

  1. 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. 

  2. 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.

  3. Metallic Mirror Coatings
    4/1/2016

    Edmund Optics offers a large variety of precision parabolic, spherical, and flat mirrors with an array of metallic and dielectric coatings to suit all application requirements in different regions of the spectrum. Standard metallic mirror coatings include protected aluminum, enhanced aluminum, UV enhanced aluminum, DUV enhanced aluminum, bare gold, protected gold, and protected silver. This application note introduces their first and second surface mirrors, enhanced metal coatings, and available custom coatings.

  4. First Surface Mirrors
    2/8/2016

    Conventional mirrors are constructed with a glass protective surface and a “silvering” second surface. In high precision applications, these second surface mirrors have distinct disadvantages such as refracted or bent images, loss of energy, and a dim and distorted reflection.

  5. 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.

  6. Care and Use of UV Laser Mirrors
    1/9/2015

    This application note provides a guideline for the caring for and cleaning of UV laser mirrors.

  7. Case Study: Specialized Thin Film Optical Mirrors Enable VIRUS Spectrograph System In Dark Energy Experiment
    8/15/2011

    PG&O designed and delivered specialized optical mirrors to Texas A&M University and the University of Texas at Austin for use in building the first-of-its-kind VIRUS (Visible Integral-field Replicable Unit Spectrograph) instrument, a key part of the Hobby-Eberly Telescope Dark Energy Experiment, or HETDEX. The $36M international research project will study the force that causes the expansion of the universe to speed up, rather than slow down

  8. Application Note: Hot & Cold Mirrors
    3/11/2011
    A hot mirror is in essence a thin film coating applied to substrates in an effort to reflect infra-red radiation either as a means to harness the reflected wavelengths for an application or to remove them from an application. By Abrisa Technologies
