ProScan Motorized Stage System for Upright Microscope | Prior Scientific

H138A 顯微鏡電動平台

XY Axis Motorized Stepper Stage (Up to 8 Slides) For High Precision Microscope Automation


The H138A stage allows you to work more productively by having the capacity to load up to eight 75mm x 25mm microscope slides.

The H138A stage for upright microscopes includes Intelligent Scanning Technology (IST) (also on the H101, H107 and H117 models).

In conjunction with extensive testing, IST allows each stage to be pre-programmed with a unique set of operating characteristics particular to that stage to ensure optimum performance.

IST allows the ProScan™III controller to make any required adjustments to maintain superior orthogonally and metric accuracy.
