Direct Laserwriter for optical lithography (Fact Sheet)
Tabletop masklessaligner with raster scan modules
Tool for virtually any application requireing microstructures like microfluidics, small scale mask-writing, micro-optics, sensors, MEMS, contacting 2D materials and fan-out electrode, etc.
Raster scan exposure mode
Draw mode for straightforward adhoc modifications to exsiting structures and electrical contacts to nanowires or 2D materials
Greyscale exposure mode allows creation of complex structures such as micro-optical devices
