Description

The ZK810T is a fixed-lens 4K UHD laser projector built for permanent installation in education, museums, houses of worship and other large venues, delivering 8,500 ISO lumens (7,200 ANSI) with a 1.26-2:1 motorised zoom lens. As one of Optoma's first true 4K UHD fixed-lens projection models, it uses a telecentric lens design for uniform sharpness across the whole image.

Full motorised lens shift and zoom make it straightforward to align the image after installation without physically repositioning the projector, and the IP5X-certified, dust-resistant optical engine supports 24/7 operation. The DuraCore laser light source is rated for up to 30,000 hours, keeping maintenance visits to a minimum over the projector's working life.

Built with an eco-friendly chassis using recycled plastics as part of Optoma's Eco Promise, and finished with dual 10W speakers and HDBaseT connectivity, the ZK810T targets large-venue installations that need consistent, high-brightness 4K UHD image quality with minimal ongoing servicing.

Planning from a real wall? Use the projector screen size calculator to upload a photo, preview the image to scale and find projectors that fit within your maximum available space. Replacing an existing projector? The projector replacement calculator checks whether this lens covers the ratio your current mount needs.

Distances are lens-to-screen, calculated from the manufacturer's stated throw ratio; allow for lens shift and mounting hardware. Always confirm against the manufacturer's installation guide before fixing mounts.
