µMLA - table tor Maskless aligner from Heidelberg Instruments Mikrotechnik GmbH.
NEW: The table-top system µMLA features our state-of-the-art maskless technology and is the perfect entry-level tool for Research & Development, in virtually all areas that require microstructures. Typical examples are Microfluidics, Micro Optics, Sensors, MEMS, and Material Science. The µMLA is flexible and customizable like no other table-top direct writing tool before and supports the use of millimeter-sized samples.
Select the exposure mode you need or even equip your µMLA with both: The Raster Scan Exposure Module provides fast exposure with a speed independent of design complexity. The Vector Module exposes continuous curves, creating smooth contours vital for applications such as waveguides. In addition, the µMLA offers a choice of 2 optical setups with different ranges of throughput and variable resolution. Within your optical setup the software allows easy switching between three configurations, optimizing resolution and speed according to your requirements.
