Such glass may have an asymmetrical structure to reduce fragments to a minimum, e.g. to protect the eyes or sensitive instrument parts. Also multiple layers of Polyvinylbutyral (PVB)-foil and glass are available (i.e. triplex glass). Float glass in different thicknesses is basically used, also tinted, anti-reflective or chemically toughened glass. The PVB-foil exhibits an extraordinary resistance as well as transmission in the visible spectrum and filter properties in the UV-spectrum. As our standard we use foil with a thickness of 0.38 mm. On request, we can also process foils, which are twice- or three-times thicker. Specifications Dimensions: Measures up to 240 mm x 200 mm. Larger dimensions on your request. The glass sizes of bent laminated safety glass are dependent on radii at app. 50 mm x 60 mm up to 250 mm x 250 mm. Strength: From 2 mm measured as laminated glass. The strength is depending on typical trade glass thicknesses and the desired laminated thickness. The table below serves as a guideline for typical structures when a 0.38 mm thick laminate is used. Surface defects and inclusions: According to your pacifications following ISO 10110, Part 7 or DIN 3140, Part 7 up to 5/1 x 0.1 Active index: <= 0.06 diopters Temperature tolerance: up to 80° C Measuring instruments for quality assurance Gloss BYK Gardner Glossmaster, Haze-Guard Plus Roughness Perthometer, White light Interferometer Transmission and reflection Spectrometer Outlines Smartscope, optical 3D- measurement Layer Resistance Climatic chamber, abrasion test Cleanliness Dark field illuminator Flatness Interferometer Surface defects/inclusions/edge chips Profile projector, digital microscope
