Precision glass optical filters optimize display clarity and contrast
June 06, 2012 // Julien Happich
Using the latest in glass fabrication and thin-film vacuum deposition technology, Dontech's VCG-Series glass filters provide exceptional optical transparency and environmental durability.
Dontech’s precision glass optical filters are incorporated in demanding military, medical, industrial and avionic applications. For high-end display programs, the VCG-Series filters optimize display clarity and high ambient light contrast (e.g., sunlight readability). Filters can be fabricated from a variety of glass substrates, such as chemically strengthened soda lime (etched or polished), borosilicate, fused silica, and optical glasses (e.g., Schott nBk-7).
The 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. The filter sizes range from less than 1” to greater than 42” diagonal, and can be sold as a stand-alone display cover glass product or integrated into a higher level assembly. The optical 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 to improve impact resistance and display contrast.

The SoCKIT evaluation kit is Arrow's latest development tool, featuring an Altera Cyclone V SoC with a dual-core ARM Cortex-A9 MPCore processor integrated within its 28nm FPGA fabric.
Altera SoCs allow embedded system developers to differentiate their end product with customized hardware and software, and extend the product lifecycle through hardware and software updates in the field. This month, Arrow Electronics is giving away five SoCKIT evaluation kits featuring Altera’s ARM-Based SoCs, worth €249 each, together with the free entrance to one of Arrow’s SoC workshops organized throughout Europe.
And the winners are...
In our previous reader offer, Freescale Semiconductor was giving away five IMX6Q, Sabre-lite kits, worth £128.06 each.
Lucky winners include Mr. X. Salada Sole from the UK, Mrs A. Peric from Germany, Mr Z. Janosy from Hungary, Mr D. Gacina from Croatia and Mr B. Boris from France. All should be receiving their packages soon. Let's wish them some interesting findings with their projects.
