Laser technology
Optoma laser projectors use high-quality lasers to create the projected image. In many situations the perceived brightness from laser illumination projectors can be twice that of an equivalent lamp-based model. They also deliver increased efficiency to maintain consistent brightness, superior colour performance, instant on/off and an extraordinary life span of up to 30,000 hours.

DuraCore
Industry leading lifetime is achieved using Optoma’s DuraCore technology. Implementing advanced laser diode cooling techniques and an innovative dust resistant design.
