Abstract
A new photometer has been designed for the measurement of screen brightness and other photometric parameters relating to projection quality. The photometer is a compact, handheld spot meter with see-through optics and an internal meter visible in the viewfinder. The photometer features a silicon photovoltaic cell and solid-state operational amplifiers for maximum accuracy, stability and repeatability, and a computer-designed glass filter for optimal matching to the spectral response of the human eye. The design, testing and application of the new photometer is described.
