41. 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

42. 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.

43. 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.

44. Beam Splitter Coatings 4/5/2011

    Beam Splitter (BS) is a term used to describe various coatings which divide a beam of light into separate beams. Dichroic filters are often called beam splitters. In this section, we will be describing beam splitters that divide light at each wavelength of interest into two separate beams. These beam splitters are typically designed for an incident angle around 45 degrees from normal.

45. Precision Glass & Optics And PRP Optoelectronics Eurofighter Typhoon Project 2/22/2011

    As experts in precision optics and optical thin film coatings, Precision Glass & Optics can customize thin film filters to meet customer specifications. In this instance, the optical coatings were designed to carefully filter out unwanted stray light from varying sources in the aircraft’s cockpit.

46. Indium Tin Oxide (ITO) & Index-Matched Indium Tin Oxide (IMITO)

    Transparent conductive coatings are very often used in electro-magnetic shielding, electrical heating, and cutting edge display applications. Abrisa Technologies uses the coating material Indium Tin oxide (ITO) which provides for excellent durable coatings. 

47. UV Blocking Glass Benefits For Dental Curing Lights

    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.

48. How To Protect Museum Quality Artwork With UV Blocking Glass

    UV Blocking Glass acts as a mirror with regard to ultraviolet light wavelengths (400nm and shorter). UV rays are one of the most significant sources of degradation in museum artwork. As such it is a problem that has prompted much consideration.

49. Using UV Blocking To Prevent Skin & Eye Damage From Entertainment Or Medical Lighting

    Throughout the past few decades, it has been established that people are being damaged by ultraviolet light from the sun, and so we are being encouraged by the medical industry to take protective measures to limit the effect the sun has on our skin and eyes. UV blocking glass is one such way we can protect ourselves from ultraviolet light damage as well as isolating UV light for specific uses.

50. Hot Mirrors Vs. Cold Mirrors

    Hot and cold mirrors “heat control filters” are types of dichroic filters used to remove unwanted energy from a light emitting source.
