  4. The Care and Use of Vacuum UV Coatings
    1/9/2015

    This application note provides a guideline for how to care for and use VUV coatings, and precautions one should take to extend the life of the coatings.

  5. Transmission and Reflectivity Measurements for Optical Coating Characterization
    1/5/2015

    This technical note discusses how to accurately characterize MLD coated optics to help prevent premature failure in a 193nm laser system.

  6. Effect of Grain Size on Microstructure, Properties, and Surface Roughness of Reaction Bonded SiC Ceramics
    12/3/2013

    SiC based ceramics feature high specific stiffness, high thermal conductivity, and low CTE. Reaction bonded SiC ceramics feature the same characteristics, but also benefit from their large size and complex shape capability. The grain size of the SiC phase can largely affect the microstructure, properties, and surface roughness in reaction bonded SiC ceramics.

  7. Understanding Optical Coatings For Military Applications
    9/4/2012

    Virtually all optical components used in military applications, such as target designation, rangefinding and IR countermeasures, employ thin film coatings to somehow modify their transmission and reflection characteristics. Yet, despite their ubiquity, many military system designers are not familiar with the commonly encountered tradeoffs in thin film design, or with the characteristics of various coating deposition technologies. As a result, optical coatings are often specified in ways that drive up cost unnecessarily. This article reviews some of the most important design and deposition factors. It is intended to help those who specify optical coatings establish a realistic set of specifications that deliver the necessary performance in the most cost-effective manner.  By Trey Turner, Chief Technology Officer, REO

  8. 90 Day Salt Fog Durable Infrared Anti-Reflection Coatings
    7/10/2012

    Proteus coatings have been developed to overcome the long standing issue of high durability with the consequential loss of transmission.

  9. 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

  10. Application Note: UV Blocking Glass Benefits For Dental Curing Lights
    7/6/2011
    Dental curing lights utilize coated glass filters, such as a UV blocking glass, to selectively emit specific bands of light. These curing lights are used to polymerize dental composites, sealants and cements that are often used to help repair or replace tooth material. By Abrisa Technologies
