ProScan HEP4

Encoded High Resolution Stage For Upright Microscopes

The HEP4 is an encoded motorized XY stage for upright microscopes and is fully customizable for integration into OEM devices.

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 HEP4 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.
