Zytronic OPTICAL FILTERS - Zytronic - #1

ILAL fILILrO

Zytronic 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 damage from impact 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 technigues.

Zytronic produces a wide range of OPTICAL FILTERS which are designed to meet specific customer reguirements for viewability of display systems in different environmental conditions.

Zytronic OPTICAL FILTERS can incorporate:

• Anti-reflection coatings to maximise transmission

• Anti-glarefinishes

• Tinted or neutral density substrates/interlayers to improve contrast

• Transparent conductive coatings for static dissipation or electromagnetic shielding

• Micro-fine mesh for electromagnetic shielding

• Circular polarizers to enhance contrast

• Transparent conductive coatings or wire heating niters for de-misting or de-icing

• Infrared coatings to eliminate solar gain

• Louvered filters for privacy viewing

• Screen printing

• Thermally tempered or chemically strengthened glass for enhanced impact resistance.

Performance Characteristics

Spectral

Optical transmission, absorption and reflectivity are determined by the characteristics and colour of the composite and coatings applied to the composite surface. Typical transmissions curves are avaiable on reguest.

Durability

OPTICAL FILTERS have been subjected to environmental tests including temperature and humidity cycling, thermal shock and vibration. No evidence of discolouration, delamination, shock abrasion or fungal growth has been observed.
