Photochromic Glass Sheet

In the absence of activating light the lenses return to their clear state.

Photochromic glass sheet.

Photochromic plastic has a reversible colour change and is activated by the uv light in sunlight and daylight. Granqvist in materials science for solar energy conversion systems 1991. It is made from optical polycarbonate sheet and photochromic film with special photochromic technology weetect photochromic sheet film wpsf can be applied to photochromic lenses photochromic sunglasses polarized photochromic sunglasses photochromic safety glasses photochromic glass. Weetect photochromic sheet film wpsf also names photochromic plastic sheet film photochromic film.

The uv creates a vivid change from clear to a coloured plastic. The core glass being more viscous at forming temperatures than that of the photochromic skin glass provides a support for the photochromic skin glass during the formation of the laminated sheet and accordingly the photochromic glass p may be sensitized on the draw immediately after the supporting laminated sheet s is formed by subjecting the. A photochromic material is characterized by its optical properties being able to change reversibly upon irradiation. Photochromic lenses may be made of glass polycarbonate or another plastic they are principally used in eyeglasses that are dark in bright sunlight but clear in low ambient.

Chameleon masterbatch can be added to many standard plastics for injection moulding and extrusion. The phenomenon is well known both in glasses 24 25 and other materials.
