Innovations in Optics has introduced LumiBright 3300B UV-LED illuminators for Digital Light Processing (DLP) applications.
The illuminators comprise a packed UV-LED array coupled to a high efficiency, non-imaging collection optic with an aspect ratio matched to DLP chips. Its integral imaging optic is telecentric over the entire DLP and is constrained in angle to match the micromirror tilt angle. Water-cooling allows the UV-LED array to be operated at a very high current density.
The illuminators support 3D printers for rapid prototyping, additive manufacturing, and tissue engineering. PC-board makers employ maskless lithography to quickly revise circuit board layouts. Traditional screen and offset plate printers use UV DLP systems for prepress digital imaging, and emerging UV DLP medical treatments require localised, high contour precision for skin lesions in dermatology.
Standard centre wavelengths include 365nm, 385nm, 395nm and 405nm. Single or dual wavelength configurations are available. Two models are available to support both 0.95 1080p and 0.7 XGA format DLP chipsets providing high radiant power greater than 15W on 0.95 DLP and greater than 9W on 0.7 DLP. Thermal management features are designed to provide more than 10,000 hours of operation.
