MicroWriter ML3 Baby
 Conventional approaches to photolithography are usually based on exposing through a chromium-glass mask manufactured by specialist vendors. In R&D environments it is often necessary to change the mask design frequently. Direct-write laser lithography overcomes this problem by holding the mask in software. Rather than projecting light through a physical mask, direct-write laser lithography rasters the sample beneath a number of computer-controlled lasers, each pulsing on and off in order draw the pattern to be exposed directly onto the photoresist
MicroWriter Baby is the smallest and lowest-cost optical lithography machine in the world and is designed to offer unprecedented value for money and small laboratory footprint. With a footprint of only 45cm x 45cm, it sits on a standard laboratory bench or desk and plugs into a laptop computer.  Its only service requirement is a standard power socket – no pumps or compressors are needed and it is almost silent in operation. It is a Class 1 laser product and so can be used in an open laboratory environment without special laser safety measures.  Easy to use Windows based software means most exposures can be set up and launched with just a few mouse clicks.
