Optical Filters

Special optical filters are used to enhance the readability of all types of electronic displays by controlling light transmission, reflection and absorption.  The filters can also provide protection of the display from abrasion and impact damage thereby extending the life of the display.

Both monolithic and multi-layer composites in glass or polycarbonate or acrylic are available.  The optical laminations are manufactured by bonding together, under carefully controlled conditions, two or more glass or plastic materials using proprietary bonding techniques. 

Zytronic produces a wide range of optical filters which are designed to meet specific customer requirements for viewability of display systems in different environmental conditions.

These optical filters comprise the following options and features :

 

  • anti-reflection coatings to maximise transmission
  • anti-glare finishes
  • tinted or neutral density interlayers to improve contrast
  • transparent conductive coatings for electromagnetic shielding
  • microfine mesh for electromagnetic shielding
  • circular polarizers to enhance contrast
  • louvered filters for privacy viewing
  • transparent conductive coatings or wire heating filters for de-misting or de-icing
  • thermally tempered or strengthened glass for enhanced impact resistance and vandal resistance
  • screen printing

 

Zytronic optical filters are available in flat or curved form in the following materials:

 

  • glass
  • polycarbonate
  • acrylic

 

A wide range of sizes are available - please contact the AMS Technical / Sales Department to discuss your specific requirements.

 

RFI / EMI SHIELDED FILTERS

Electromagnetic Interference (EMI) can be described as any form of electrical disturbance, signal or noise which interferes with the ability of electrical or electronic equipment to function correctly.

This interference is also referred to as Radio-Frequency Interference (RFI) and is active throughout the environment.  Its effects vary from impaired TV or radio reception to severe disruption of communications, data processing and medical and defence activities.  Its sources are both natural and man-made.

It is also necessary to contain emitted signals from computer and data handling equipment to prevent electronic eavesdropping for example, where these signals may interfere with other sensitive electronic equipment in the nearby vicinity.  The simplest way to achieve this is by the Faraday Cage Principle and in effect, this is what happens in most cases (metal frames or casings placed over the source of the emission).

Our shielded windows are an extension of this principle in that the fine wire mesh acts as a barrier to these emissions but at the same time allowing the operator sight of the display into, or out of the shielded room or area.  The windows on their own will not solve RFI problems but must be an integral part of a fully shielded system.

Typical applications include:

 

  •  Military Displays - battlefield tactics systems
    - communication systems
    - hand-held computers
    - secure laptop computers
  • Secure Areas - computer rooms
    - test chambers
    - buildings
  • Information Displays - airport terminals
    - rail terminals
    - bus terminals
  • General - telecommunication racks
    - test and measurement equipment
    - navigation equipment
    - medical equipment
    - radar applications
