  1. Benefits Of Heat Tempering vs. Heat Strengthening Of Glass

    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.

  2. Metallic Mirror Coatings

    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.

    Abrisa Technologies' new CleanVue PRO series of anti-reflection coatings are designed to combine improved handling, cleaning, water shedding, and robust performance with anti-reflective properties. 

  4. Care and Use of UV Laser Mirrors

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

  5. The Care and Use of Vacuum UV Coatings

    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.

  6. Transmission and Reflectivity Measurements for Optical Coating Characterization

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

  7. Effect of Grain Size on Microstructure, Properties, and Surface Roughness of Reaction Bonded SiC Ceramics

    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.

  8. Understanding Optical Coatings For Military Applications

    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

  9. 90 Day Salt Fog Durable Infrared Anti-Reflection Coatings

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

  10. Case Study: Specialized Thin Film Optical Mirrors Enable VIRUS Spectrograph System In Dark Energy Experiment

    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
