Description

The piezo focus positioner MIPOS 250 was developed for finely adjusting micro objectives and object lenses. The maximum motion is 250 µm. The resolution of the MIPOS 250 is very high, and in practice only limited by the voltage noise of the power supply.

All kinds of standard threads for Zeiss, Leica, Nikon, Olympus etc. are available for the top and bottom sides of the MIPOS system. Mounting this system onto the microscope is very easy – screw the Flex-Adapter thread ring into the microscope and mount the MIPOS 250 for piezo focus fine adjustment on this ring with a screw. Because of the small size, no other threads beside the MIPOS are blocked.

To avoid drift and hysteresis, there is the option of equipping the MIPOS with an integrated strain gauge measurement system “SG”. And, the MIPOS 250 can be used in inverse microscopes – upside down.
