Chapter 1 Overview
1.1 Introduction
The MLS203 uses internally integrated brushless DC servo motors with optical linear
encoders to provide an industry-leading, high-speed, compact scanning stage for
microscopy. This innovative design eliminates the external motor housings that create
mechanical clash points and impede access to the sample. It is ideal as a drop-in
upgrade replacement for the stage on Zeiss Axio Observer and Axiovert 40
microscopes.
The scanning stage can be positioned with a resolution of 0.1 µm and repeatability of
0.25 µm, at speeds up to 250 mm/s. The high-quality construction uses high-rigidity
precision linear bearings, commercial grade limit switches, and powerful brushless
linear DC servo motors. In addition, the number of moving parts has been minimized,
which optimizes the lifetime and reliability of the scanning stage.
Accessory plates are available for the stage to allow the positioning of standard
microscope slides and petri dishes, well plates and custom sample holders.
The MLS203 stages should be driven by the BBD series of brushless DC motor
controllers. These controllers include the Thorlabs apt software suite, which provides
an easy-to-use graphical interface for stand-alone operation as well as programming
support for integrated applications. The controller can also be used with most third
party software packages.
