POLOS NanoWriter

POLOS NanoWriter

Product description

The POLOS® NanoWriter is a versatile UV laser writer with high precision components specifically designed to give the user the highest degree of freedom to create microstructures in photosensitive layers. The NanoWriter is a fully operational base system. It includes a 405 nm optical module capable of writing structures as small as 0.8 µm in photoresist layers. This user-friendly tool supports up to 4095 levels of grayscale or pure binary mode and allows for 2.5D optical structures, surface structures as well as mask projects. Real-time laser-controlled autofocus and laser intensity control ensure high-quality imaging during the entire exposure process. The control electronics are all mounted within the frame, except for the control PC. This Microsoft Windows-based desktop PC and all required software is included in the package.
