Since 1971, Dontech has provided customers with proven optical filter designs, rapid prototyping, and consistent high product quality. Practical knowledge gained from many years of “hands on” optical display filter design and fabrication is applied to customer specific applications, providing Dontech with the resources to recommend the most cost effective and practical designs and product options. Dontech’s diverse technical staff of engineers and scientists allows Dontech to work with its customers in developing new and higher-performing optical filters and display assemblies. Typical optical filter applications include:

  • LCDs
  • Optical Components & Assemblies
  • Organic Light Emitting Diodes (OLEDs)
  • CRTs
  • LEDs
  • Electroluminescent (EL) Displays
  • Plasma Displays
  • Vacuum Fluorescent Displays
  • Electronic Equipment Cabinets and Enclosures
  • Structural and Shielded Windows
  • Instrument Panels

Dontech’s dynamic product line of optical filters, enhancements and assembly services is supported by fabrication experience and capability with an extensive range of optical substrates, colors, in house thin and thick film coatings, optical laminations, and ancillary products. This depth allows Dontech to meet even the most demanding customer application requirements. Electronic display enhancements are typically governed by three primary application requirements:

• Optical Performance Improvement – (e.g., increased brightness, contrast enhancement, reduced glare, better viewing angles, night vision compatibility)

• EMI/RFI Shielding – Susceptibility or radiated emissions compliance for military (e.g., MIL-STD-461, MIL-STD-464), FCC, Secure communication (e.g., Tempest), ISO and VDE requirements.

• Environmental – Suitable durability for high or low temperature extremes (e.g., -65ºC to +85ºC) is integrated into construction of the product. Ruggedness ranging from the military requirements (e.g., MIL-STD-810 sand, dust, salt, water, chemical resistance, humidity, impact, shock and vibration) to the commercial abrasion, chemical, and cleaning requirements, are also addressed.

Dontech’s facilities are equipped with the current generation of design, manufacturing, and test equipment with methods and procedures in place to ensure product compliance and verification of designs. Dontech application engineers can recommend the most suitable optical filter or display enchancement design to meet virtually any display or optical assembly enhancement application.
