Description
The Ricoh PJ UHL3660 is a 4K UHD (3840x2160) ultra-short-throw laser projector built around a 0.65-inch DLP chip with Ricoh's OptiBright dual-laser and phosphor-wheel light engine. With a throw ratio of 0.24:1 it can produce an 85-inch image from around 1cm away from the screen, making it well suited to boardrooms and huddle spaces where a conventional throw distance isn't available.
Brightness is rated at 6,500 lumens with a contrast ratio of 5,000,000:1, and Pixel Quadrupling Technology helps deliver crisp detail from 4K sources. The laser light source is rated for up to 40,000 hours of maintenance-free operation, and 360-degree installation (including portrait orientation) supports mounting on the ceiling, floor or wall.
Connectivity includes HDMI 2.0 and HDBaseT for long cable runs, plus wireless projection via Miracast for both Windows and Android devices, making it straightforward to integrate into modern collaboration spaces.
