About Casper / Tech Privacy

Casper Cloaking Technology, distributed by SOLYX® as part of the Specialized Functions collection, is a precisely engineered optical film that makes LED and OLED screens appear dark through the film while leaving the surrounding space fully visible. The effect is specific to screen wavelengths: a Philadelphia office manager inside a glass-walled conference room sees their presentation, dashboard, and client data normally. A visitor or competitor looking through the glass from the outside sees a dark screen — as if it were turned off — while the room, the people, and the conversation remain fully visible.

For Philadelphia law firms, financial services companies, pharmaceutical firms, and technology companies in Center City and University City, Casper film solves a specific and growing security problem: the glass-walled office aesthetic that tenants and architects want conflicts with the screen privacy that sensitive work requires. Before Casper, the only solution was to cover the glass — frosted film, blinds, roller shades — which eliminated the openness that the glass was installed to provide. Casper preserves full visual openness while protecting screen content specifically.

Casper is distributed exclusively through Designtex and is installed by authorized applicators. Window Film Philadelphia is an authorized Casper installer for the Philadelphia region. The film is available in a lightly frosted version that adds a minimal privacy texture to the glass in addition to the screen-blocking function.

Casper film applies to interior glass surfaces and is designed for permanent installation. It is compatible with standard commercial glass types including tempered and laminated panels.
