Description
The ZK810TST is the short throw variant of Optoma's ZK810 series, delivering the same 8,500 ISO lumen (7,200 ANSI) 4K UHD image quality through a 0.65-0.75:1 fixed telecentric lens designed for close-proximity installation. It's aimed at the same large-venue applications as the standard-throw ZK810T - education, museums, houses of worship and immersive display - where the projector needs to sit closer to the screen. Full motorised lens shift and zoom make post-installation alignment straightforward, and an IP5X-certified dust-resistant optical engine supports continuous 24/7 operation. The DuraCore laser light source is rated for up to 30,000 hours, giving a long service life with minimal maintenance. Finished with an eco-friendly chassis made from recycled plastics, dual 10W speakers and HDBaseT connectivity, the ZK810TST suits fixed installations where a short throw lens is required alongside high brightness, true 4K UHD resolution and long-term reliability.
