UV FLOOD EXPOSURE SYSTEMS

B&A offers a variety of high performance, collimated, and uncollimated UV Flood Exposure Systems. These systems are enhancing many of the photolithographic processes used by the Microelectronics Industry.
These exposure systems are designed for use in production as well as R&D applications. Near, Mid, and Deep UV systems are available with a variety of standard and optional features including beam sizes to 16" (400mm), intensity controlling powersupplies, and up to 2,000W capability.
The system's exposure optics employ a proven, high performance optic train that employs an elliptical reflector, a multi-element optical integrator system, heat removing primary and secondary mirrors, and output optics.
