White Flashed Opal
White Flashed Opal glass consists of a colorless base soda-lime glass which is fused to a thin white flashed layer. Using White Flashed Opal, one can create an ambiance in diffused lighting similar to daylight with very little shadow. Flashed opal is perfect for creating a pleasant atmosphere in professional or residential areas.
The transmission properties of White Flashed Opal Glass are for the most part dependent solely on the white layer, the thickness of which varies over the manufacturing width and is generally in the order of 0.45 ± 0.20 mm. The visual light transmission in the case of standard illuminant A is on average τ vA = 35 % (± 10 %).
In the visible range of the spectrum DESAG White Flashed Opal Glass gives almost ideal diffusion. In the near infrared range a directed component is superimposed which appears on the diffusion indicatrix (fig.> 2) as a small “nose”. From λ = 800nm, the proportion of the directed transmission increases relatively sharply and where λ = 2000 nm, values of 50 % may be reached.
White Flashed Opal glass is largely insensitive to the action of water, acids, alkalis and salt solutions (with the exception of hydroflouric acid).
