ProScan HE16/2


Encoded Motorized 8-inch Travel Stage For Upright Microscopy

The ProScan HE16/2 encoded motorized XY stage for upright industrial microscopy is compatible with Prior's OpenStand-L platform and is fully customizable. 

It has a long travel range and 25 kg load capacity for scanning large, heavy samples such as 8-inch semiconductor wafers, flat panel displays and printed circuit boards up to 200 mm diameter

The HE16/2 has linear encoders for exceptional long-range repeatability and a 2 mm ballscrew for a balance of speed and resolution. Prior's patented Intelligent Scanning Technology (IST) to enhance accuracy and linearity. It scans large industrial samples reliably and efficiently.

Other drive configurations for increased speed may be available depending on your region. 

It is compatible with transmitted light applications and provides easy access for loading samples.
