H275LMT


Extended Travel Motorized Focus Tower

The H275LMT motorized focus column provides fast, controlled movement of optical systems with up to 145 mm of vertical travel

The interface between the optical system and the H275LMT is interchangeable, making it compatible with commercially available stereo and compound microscope optics and for developing customized optical systems.

In combination with Prior’s complete OptiScan and ProScan motorized stage range, the H275LMT can be used to image large samples (up to 300 mm x 300 mm). 

The system’s high load capacity of 25 kg enables large and complex assemblies to be translated above the sample.
