Dontech glass filters optimize display clarity and contrast

June 14, 2012 — Dontech released the VCG-Series glass filters, formed with next-generation glass fabrication and thin-film vacuum deposition technology to provide exceptional optical transparency and environmental durability in displays.

Dontech’s precision glass optical filters are incorporated in demanding military, medical, industrial and avionic applications. 

The VCG-Series filters optimize display clarity and high ambient light contrast (enabling sunlight readability). Filters can be fabricated from chemically strengthened soda lime (etched or polished), borosilicate, fused silica, and optical glasses (e.g., Schott nBk-7).

VCG-Series filter customization options include high-energy vacuum deposited coatings such as antireflective, transparent conductive (EMI shielding, transparent heaters), and infrared (IR) or near infrared (NIR) blocking. Additional features include custom screen printing, polarizers, precision machining, and conductive optical grids (woven, etched and printed).  Dontech’s glass filters can be laminated or monolithic, clear or colored.

Filter sizes range from less than 1” to greater than 42” diagonal, as stand-alone display cover glass or integrated into a higher-level assembly. VCG-Series filters can be assembled into frames or bezels, or optically bonded to LCDs or touch screens by Dontech using its proprietary IMO-bond optical bonding process.

Dontech, Inc. is an ISO-9001:2008 certified designer and manufacturer of optical filters, coatings, and enhanced display solutions for military, medical, industrial, and avionic applications. Web: www.dontech.com.
