Impactinator®-glas

Antireflectiecoating

Heat Treating: Where the annealed glass is subjected to a special heat treatment in which it is heated to about 680°C and afterwards cooled.

Chemical Strengthening: The glass is covered by a chemical solution which produces a higher mechanical resistance. Chemically - strengthened glass has similar properties to thermal-treated glass.

Using the same technique of evaluation with pencils as the Elcometer 3080 , this instrument enables the pencil lead to be maintained at a constant force of 7.5N, and at the appropriate angle - which increases the reproducibility of the test.

Linear thermal expansion is a critical factor to consider in environments with wide temperature requirements. The problem is caused by different [thermal expansion coefficients of the touch screen materials] or the bezel structure.
