Borosilicate Glass • Glasslite provides Borosilicate glass for lights which require resistance to extreme heat, thermal shock and chemicals.   Applications: - Floodlights/Spotlights. - Downlights. Special Properties:   • Low thermal expansion. High thermal shock   resistance and its ability to withstand temperatures up to 450ºC.   RTG (resistance to thermal gradients): 120 - 160°C. RTS (resistance to thermal shock): 150 - 200°C.     (All values for RTG and RTS are empirical values which diversify with thickness, size, finishing and conditions of assembly. Values can be above or below target).   • High transparency in the UV/visible/near IR range.   • Optimum glass quality.   • Mirror-like finish on both surfaces.   • High degree of flatness.   • Chemical resistance.   • Glass thickness: standard stock:   2mm - 3mm - 5mm. Standard tolerances .3mm.     Note Other thicknesses available on request. These are an import item: surcharge, minimum quantities and lead times apply.   • Processed in a wide variety of shapes and sizes,   to meet specific requirements.   • Sandblasted finishes.       • Substrate Glass for Special Coatings.   With different coating technologies thin films on the glass open up a wide range of possible applications: − Dichroic Colour Filters. − Food Enhancement Filters. − Colour Correction Filters. − IR Filters.
