The LumiBright 3300B UV-LED illuminators for target Digital Light Processing (DLP) applications such as 3D printing, maskless lithography, prepress digital imaging, phototherapy, and refractive surgery. DLP technology, the brainchild of Texas Instruments, uses millions of tiny mirrors to digitally produce an image with a light source. When used with ultraviolet (UV) light and photosensitive materials, DLP offers continuous scanning, as well as selective and overlapping exposures with greater throughput and efficiency than flying spot laser systems. The Model 3300B UV-LED illuminators consist of a densely 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 micro-mirror tilt angle. Water-cooling allows the UV-LED array to be operated at a very high current density. The Model 3300B UV-LED Illuminators for DLP 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 utilize UV DLP systems for prepress digital imaging. Emerging UV DLP medical treatments strive for localized, high contour precision for skin lesions in dermatology and for corneal disorders via collagen cross-linking in ophthalmology. Standard center wavelengths include 365 nm, 385 nm, 395 nm and 405 nm and single or dual wavelength configurations are available. Two models are available to support both 0.95 1080p and 0.7 XGA DLP chipsets.
