Elrepho with liquid cooling unit |
The Elrepho with its integrating sphere (diffuse) geometry was adopted by the European and Canadian Paper Industries and ISO created ISO 2469 as the standard for measuring brightness. The Elrepho remained the only instrument manufactured in accordance with European, Canadian and ISO standards until Technidyne Corporation introduced the Technibrite™ TB-1 in 1980.
Since that time Technidyne has developed and manufactured several generations of diffuse instrumentation according to ISO 2469 (Technibrite™ TB-1 [2-piece], Technibrite™ Micro TB-1C, Technibrite™ TB-1 [1-piece] & Color Touch™ family). The Color Touch™ was initially released in 1994. This instrument changed the capabilities of diffuse instruments with unique features such as automatic calibration (no manual data entry), an internal swing-in standard and an integrated computer with touch screen interface. These are all still uniquely Technidyne Color Touch™ features.
