Innovations in Optics has launched its next generation LumiBright 3300B UV-LED Illuminators for Digital Light Processing (DLP) applications such as 3D printing, maskless lithography, prepress digital imaging, phototherapy and refractive surgery. According to the company, the UV-LED technology offers reliable and economical advantages over lasers and arc lamps in UV DLP systems.  High optical power over 20W matches the power output of fiber-coupled laser diode bundles at lower cost. The Model 3300B series of UV-LED Illuminators for DLP comprises a densely packed UV-LED array. Standard LED center wavelengths include 365 nm, 375 nm, 385 nm, 395 nm and 405 nm. Single or multi-wavelength configurations are available.  The combination of different wavelengths optimizes the spectral balance of the exposure for all types of UV processed materials. 

The multi-wavelength feature, in maskless lithography for manufacturing printed circuit boards, supports many photoresists, ranging from general-purpose dry film to conventional solder mask. For prepress operations in the printing industry, computer-to-plate (CtP) systems with UV-LED can support highly cost-efficient, mature UV-plate technology.  In computer-to-screen (CtS) printing, UV LED and DLP exposure eliminates the need for several consumables and production steps improving process efficiency at lower cost with higher quality.
