  1. Messages From Above - Optical Satcom Lights The Way

    We live in the “Communications Age”, but there is still further evolution to come that will necessitate extending the communications reach even further.  While we have laid down a large physical infrastructure of wireline fiber-optic networks and wireless cellular base stations, the next advances in communications, 5G and machine-to-machine communications, will require “help from above” to blanket literally every corner of our planet with high speed, ultra-low latency, secure networks – telecom meet satcom. 

  2. What Is A Front Surface Mirror?

    This article identifies the differences a front surface mirror has from other types of mirrors and the benefits of its use.

  3. What Is An EMI Shielding Window?

    An EMI shielding window is an optically transparent, electrically conductive barrier that significantly reduces the amount of electro-magnetic radiation that might pass through it. This article covers the different types and their uses and benefits.

  4. What Is A Transparent Heater Window?

    Transparent Heater Windows are used for widely differing purposes from keeping food hot or cold to preventing aircraft windows from frosting over. This article covers their many uses and benefits.

  5. Physical Vapor Deposition – Sputtering vs. Electron Beam Evaporation

    Physical Vapor Deposition (PVD) is a family of processes that is used to deposit layers of atoms or molecules from the vapor phase onto a solid substrate in a vacuum chamber. Two very common types of processes used are Sputtering and Electron Beam Evaporation, which are described in this article.

  6. What Is A Thin Film Optical Coating?

    Thin film optical coatings are applied to optical substrates such as glass to alter or change its optical properties. This article provides a brief overview of their function and the different types available.

  7. Glass Surface Quality – Scratch/Dig Specifications

    Scratch/Dig refers to cosmetic defects found in glass from the manufacturing and/or handling process. This article describes the difference between scratches and digs as well as their specifications.

  8. What Are The Benefits Of Low Iron Soda Lime Glass?

    This article provides an overview of the benefits of low iron soda lime glass.

  9. Glass Strengthening Methods

    Strengthening glass can be done via three primary processes; tempering, thermal strengthening and chemical strengthening in order to increase the heat resistance and overall strength of the glass. This article provides an overview of all three processes.
