Suited for use in normal cinema environments, Qalif Optimiser technology forms part of Harkness' Curolux Silver solution allowing exhibitors to measure and maintain screen parameters and monitor and modify projection equipment settings. A small and discreet addition mounted to the back wall of a theatre, Curolux silver solutions are powered by Qalif Optimiser technology. From 144 point screen brightness measurement and light uniformity through to focus correction, Curolux Silver solutions act as a cinema screen auto-calibration solution, automatically measuring projection quality and autonomously altering projector settings to maintain the best possible viewing experience from digital cinema equipment. Additionally, Curolux Silver solutions are able to carry out spectral analysis of each audio channel to monitor volume levels and identify malfunctioning sound units.
