OSM-Z-100B - Objective Scanning Mechanism

Queensgate’s latest Dual Sensor Technology is used by Queensgate to achieve superior dynamics and accuracy in microscope objective focusing. Sub-nanometre positioning is offered by the OSM over a total displacement of 100 µm with an unbeaten step and settle time of below 4ms.

The non-contact position measuring system, NanoSensors of the company offers excellent resolution, consistency and stability at nanometer level. Low off-axis errors as well as extremely high stiffness improve the performance of this sophisticated design. Several digital and analogue controllers are offered to drive the OSM-Z-100B including the newest NPC-A-1110DS analogue controller supporting patented Dual Sensor technology.
