CMZ50 is an ultra-short-throw projector for well-lit hy-flex learning and meeting spaces. It delivers an 80-inch image from about 1 cm (1/3 in.) avoiding shadows on the screen. Laser light source develops 5200 lm with 3000000:1 Dynamic Contrast. Watts-per-lumen efficiency is about 31% better than other lamp-based short-throw models and no light-source or filter maintenance is required for 20000 hours.
