FB203 Motorized Linear Stage


Z-Axis Motorized Focusing Mount

The FB203 motorized linear stage is the basis of the FB range of Z-axis motorized vertical translation stages: FB204, FB205, and FB206. It has mounting holes for easy installation into OEM designs or customized instruments.

The long 38 mm travel range of the FB203 is suitable for multiple applications and enables easy access to the sample by moving the objectives out of the way.

Its sub-micron repeatability ensures that translated objects are repositioned precisely.

A high load capacity of 14 kg enables the FB203 to be used with customized mounts and a variety of XY platforms.
