Spectra CineSpot Spotmeter is exclusively designed to measure screen brightness and uniformity in theaters, review rooms. CineSpot has received one of the highest awards from the Academy of Motion Picture Arts and Sciences
The economical, compact CineSpot 1° Spotmeter from Spectra Cine has been designed for easy use and for making simple yet accurate screen brightness measurements and other field measurements. The CineSpot features eye-level, magnified, thru-the-lens viewing of the 1° spot area in a large (21° diagonal) rectangular viewing field, with simultaneous display of the meter reading superimposed in the viewing field.
For accuracy, each individually calibrated instrument uses an ultra-stable silicon photodetector, together with computer-selected glass filters to Readbility of the CineSpot extends from 0.5 to 300 foot-lamberts, with excellent resolution in the critical 10 to 30 foot-lambert region.
