LPKF ProtoLaser LDI universal, high-resolution, table top laser direct imaging (LDI) system for prototyping on resist-covered substrates provides a software-selectable 1 or 3µm laser beam spot and a working area of nearly 4 x 4 inches. System is optimized for creating the ultrafine features required by the microfluidic and MEMS industry. The compact software combines functionality with powerful, yet user-friendly software. The UV based laser system activates UV resist-covered substrates – directly from CAD. Product eliminates the need for alignment equipment and expensive exposure masks with long lead-times. The process can be utilized on a wide variety of substrates without any special environmental conditions. The substrate is inserted using either a standard or custom cartridge for easy change-over from job to job.
