Product Summary
The Optoma ZK810T and ZK810TST are high-brightness professional 4K UHD laser projectors designed for permanent installations in education, museums, visitor attractions, houses of worship, auditoriums, large venues, simulation environments and immersive visual displays. Both models combine an 8,500-lumen DuraCore laser light source with DLP projection technology to produce bright, detailed images at a native resolution of 3840 × 2160.
The two projectors share the same core imaging platform but use different fixed lenses. The ZK810T features a versatile standard-throw lens with a 1.26–2.00:1 throw ratio and 1.6× motorised zoom. The ZK810TST uses a 0.65–0.75:1 short-throw lens with 1.15× motorised zoom, allowing a large image to be produced where the available distance between the projector and screen is limited.
Installation is supported by motorised zoom, focus and horizontal and vertical lens shift, making it easier to align the image without physically repositioning the projector. Keystone adjustment, four-corner correction, 360-degree installation and portrait operation provide additional flexibility for conventional screens, digital signage, projection mapping and creative immersive applications.
Optoma’s DuraCore laser system provides up to 30,000 hours of operation, while the independently tested IP5X-rated optical engine helps protect internal components from dust. Both models are suitable for continuous 24/7 use and include HDMI, HDMI output, HDBaseT, LAN, RS-232 and 12V trigger connectivity for integration into professionally controlled AV systems.
