The Stage STB44xxx is a premium quality, ballscrew, stepper motor driven, microscope stage that offers 4" x 4" of travel in a thin (34mm thick) X, Y stage. While controlled in open loop, The stepper motors provide for no servo jitter while still maintaining a positive return force at position. An optional .5um resolution linear encoder is available that can provide closed loop control if needed. The stage has a maximum speed of 25mm/sec. The speed can be controlled via the USB (COM Port). The stage has a standard circular dovetail mount that allows it to easily attach to most microscopes. As always, we can add your custom design hole or bolt patterns (top or bottom) for you specific application. The ballscrew stage provides 2um (1um unidir) repeatability with a submicron resolution. The unit also offers control of the Z-axis. The optional Z-axis drive easily attaches to most microscopes and provides up to 0.05um resolution. The stage system comes with our standard XYZ controller. There are two configurations of the controller. A desk top unit with built in joystick and an under the desk unit with remote joystick. Either controller provides precise control of the X, Y axis speed through an exceptionally smooth joystick. The speed is proportional to joystick deflection with velocities from as slow as single steps to full traverse speed. Remote focus of the z-axis is provided via a focusing knob on the controller. The unit also provides three user selectable sensitivities for the joystick and Z-encoder for added control. The unit con be controlled manually or through standard USB (COM Port) commands. The controller provides a display of X, Y and Z coordinates locally on an LED display. These coordinates are also available via USB (COM Port). Each stage axis has a built in unique serial number and EEProm for various stage parameters. The stage STB44xxx is an economical unit that works well in a number of applications. It comes standard with a 116mm square glass window. There is a list of Inserts available for this stage. There is also a Well Plate (compatible with 24, 96, 384 wells) top or a solid top with a custom hole pattern.
