ProScan HEP4DMLS


Encoded High Resolution Stage For Leica DM-series Microscopes

The HEP4DMLS is an encoded motorized XY stage adapted for Leica upright microscopes.

The most accurate and precise stage in the ProScan H101 range, it uses a 1 mm pitch ballscrew and 400-step motor drive configuration to provide four times the resolution of the H101A stage, making it ideal for applications that require reliable, short stage movements. 

Linear encoders ensure long-range repeatability while Prior's patented Intelligent Scanning Technology (IST) optimizes stage accuracy and linearity.

The HEP4DMLS accommodates a variety of specimen types including glass slides, multiwell plates, semiconductor wafers, and metallurgical samples. Alternative drive configuration options may be available depending on your region.

See the product compatibility tab for the full list of options available.
