Ultra short throw laser projector

The Ricoh 432684 is a DLP projector with a 0.241 throw ratio, producing a 4K UHD image from 39 to 14.96 inches away. It suits meeting rooms, galleries or home cinemas where space in front of the screen is limited.

6,500-lumen laser light source

Dual laser light sources with OptiBright technology deliver 6,500 lumens and a 5,000,000:1 contrast ratio. The solid-state engine replaces lamp-based models that need regular bulb changes and lose brightness over time. The jump is worth it when you need consistent output for years without maintenance downtime.

Sustained brightness and colour stability

Constant Power mode runs the laser at full output for 20,000 hours while Constant Luminance mode maintains calibrated brightness for 26,000 hours. Eco and Long Life modes extend the light source to 30,000 and 40,000 hours respectively. Image quality holds steady during long sessions instead of fading as a traditional lamp ages.
