The PicoMaster is a versatile UV laser writer with ultra-high precision components, specifically designed to give the user the highest degree of freedom to create microstructures in photo sensitive layers without the need for a photomask. The system includes a 405 nm optical module capable of writing structures as small as 200 nm in photo resist layers. This user-friendly tool supports up to 4095 levels of grayscale or pure binary mode and allows for 3D optical structures, surface structures, as well as mask projects. Real-time laser controlled auto focus and laser intensity control ensure high quality imaging during the entire exposure process.  System can process samples sizes ranging from small pieces up to 200mm wafers.
