- Abstract
- The illuminator provides a luminous 8- by 10-in. screen for the purpose of illuminating test pattern transparencies. The brightness is continuously variable over the range of 25 to 250 fL. The uniformity of brightness is better than 5% and the color temperature of the illumination remains constant at any brightness setting in the operating range. It is now used in all major production studios of the CBC to illuminate precision-made photographic transparencies, supplanting the reflectance chart for routine studio TV camera alignment. Recently developed improvements in the design make possible a controlled screen brightness of up to 1,200 fL.
