PSNL (PinballShop.NL) Optically Coated (Both Sides) Tempered Glass, specifically designed for use in Pinball Machines.
Manufactured in Germany with the highest quality coatings.
These coatings are chemically etches into the glass and hardened by the tempering process.
The process ensures that the coatings remain after many years of cleaning it and also produces a VERY SMOOTH SURFACE, unlike a "sputtered" or "spay-painted" product.
This glass is a far better manufactured product than other (budget) non-glare glass that is currently in the market.
All of the edges of this glass are also sanded, so it does not have sharp edges, again unlike other products currently in the market.
It does not 100% get rid of the DMD glare, which at such an angle is impossible to completely get rid of due to physics.
We suggest also using a DMD glare guard, see related products below, which completely gets rid of this and is a total solution for a win-win situation.

The Optical Non Glare Glass reduses 99% of all glare.
Normal Glass produces a measurable visible glare of 8% Reflection.
Our Optical Non Glare Glass measures between a Maximum Tolerance of 0.5% - 0.7%

The closer the viewing angle is to 90 degrees, the more amazing the non-glare effect will be.
All colors are 95% more brighter and there appears to be more depth (3D feeling).
