Visit Gamma Scientific in Booth 633 at SID Display Week to see live demonstrations of our new Thin Film Measurement Systems.

Display Week 2013 is being held at the Vancouver Convention Centre in Vancouver, Canada from May 21-23, 2013.

Isolated First Surface Testing of AR Coatings

Our Thin Film Measurement systems provide isolated first surface measurement of anti-reflection coatings on substrates down to 0.5mm thick.

The unique design of our instruments allows manufacturers to perform single sided inspection on the first surface of any glass of polished, transmissive element while excluding the second surface. This application has been optimized for testing anti-reflection coating on display glass for flat panel monitors, tablets and mobile phones.

azazo:

A new calibration technique for improving the accuracy of chromaticity and luminance values obtained from a tristimulus colorimeter has been developed. Matrix manipulations similar to ASTM standard practice E 1455 are applied with a goal of minimizing the errors in x, y, and Y measurement, rather than those of the tristimulus values X, Y, Z. Correction matrices are determined from CRT colors, as well as CRT colors together with other light-source colors.

This post provides an overview of key concepts in display and monitor calibration, with emphasis on general concepts and concise descriptions. Topics include photometric measurements (luminance, contrast ratio, gamma), color measurements (chromaticity, color temperature, gamut mapping, dominant wavelength and purity, white balance/gray balance) and multidimensional characteristics (uniformity, reflection, BRDF, MTF).

Photometry is the science concerned with measuring human visual response to light. Because the eye is a highly complex organ, this is by no means a simple task. It involves the meeting of many disciplines: psychology, physiology, and physics among them.
