True black quality with high contrast ratio of 10,000:1
The Wire Grid adopted in the optical engine is an organic light reflection polarizing plate made from arrays of aluminum ribs with a width of a few tens of nanometers, aligned with a pitch of over hundred nanometers on the surface of a glass substrate. It has lower angle dependency for polarized light, effectively minimizing any leakage of light to the lens when the image is black. Besides, technology to reduce variations in orientation, applying new liquid crystals, and new orientation technologies achieve a 20,000:1 device contrast ratio. The combination of the new engine and new devices DLA-SH4K delivers 10,000:1 high-contrast native images.
3500 lumen light output
A new optical design featuring a 825 W Xenon lamp generates 3500 lumens power, and delivers excellent color rendering. Lamp power is adjustable in eight steps over the range from 825 to 660 W.
Small, lightweight, and stackable design
The new DLA-SH4K achieves approximately a 65% reduction in area compared to a conventional projector of the same class, and weighs 59 kg (lens included). Moreover, the stackable design means greater installation efficiency for applications such as stack and 3D
