Description
The ZW350ST is a compact WXGA short throw projector from Optoma's DuraCore laser range, built for maintenance-free, all-day operation in classrooms and small-to-medium meeting spaces. Its short throw ratio of 0.521:1 lets it fill a large screen from close to the wall, keeping the presenter's shadow and glare out of the image, while the fixed lens keeps the design compact and lightweight.
Behind the 3,600-lumen output sits a sealed, IP6X dust-resistant laser light engine rated for up to 30,000 hours of use, removing the cost and downtime of lamp replacements. An external power supply trims the footprint further and cuts standby draw, and the laser source reaches full brightness instantly with no warm-up delay.
With a 300,000:1 dynamic contrast ratio, a built-in 15W speaker and flexible connectivity including dual HDMI, the ZW350ST is well suited to everyday teaching and presentation use where a bright, low-maintenance short throw image is the priority.
