(5) Opal glass is a superior diffuser to ground glass because it depends upon the scattering of light by particulate matter suspended in the glass itself rather than a surface reaction. It is correspondingly less efficient in overall transmission.
(12) Fused silica windows are used both for their superior heat resisting properties and for spectral transmission characteristics. Choose sapphire windows for high temperature stability combined with high infrared transmission.
(4) Ground glass is used for diffusing light, and ROLYN ground glass is superior for this purpose because of its fine grind and evenness of finish. 500 Grit.
(3) All microsheet has sharp edges and is very fragile. Handle with care. Scribe cut tolerances +/-.4mm 80-50 scratch-dig. Ideal for beamsplitter substrates.
