What makes a SmartStage Linear Positioner unique?
A typical linear stage requires a bulky expensive external controller, motor drive circuit, feedback interpolation, limit and home input circuits, as well as multiple cables per axis. With a SmartStage positioner, the high performance controller and all hardware to position the stage are built-in. A SmartStage Linear Positioner delivers all this capability in an ultra-compact package. Only a single stationary cable is required to control up to a 2 axis stage. This innovative approach is covered by US Patents 10,374,530 and 10,367,436.
What about the XY stage performance?
Dover Motion’s unique, patented stage architecture which embeds the encoder feedback circuit, limit and home sensors, digital I/O, 3 phase PWM drive, and high-performance controller inside the stage. By embedding what used to be multiple cables and external electronics, the control is seamless, and performance-optimized for low noise. The result is ultra-high stage performance with 5nm resolution and no backlash.
What else do I need to get started?
Just a power supply and computer! Dover Motion provides a user interface, software libraries, manuals, and code examples. Each stage is factory configured and tested to ensure the highest quality out-of-box performance.
Microscope Stage Application Examples
The XYZ 3 axis stage application example images show the SmartStage XY with Dover Motion’s DOF-5 stage mounted vertically for Z sample motion which combined provide 3 axes of XYZ motion. The SmartStage XY stage comes with various configurable travel options to accommodate different sample sizes. For automating microscope stage motion of a typical single slide (sized 75 x 25 mm) the 100 x 50 mm travel range stack will provide plenty of motion to load and move the entire sample under a camera. If multiple slides are placed in a single slide holder, as shown in the above image, the 150 x 100 mm travel SmartStage XY configuration will work best. This same travel can also be used to position a typical well plate.
Linear Translation Stage Position Triggering
Many precision motion applications require a signal to trigger a device that is synchronized with the position of an XY linear translation stage. The simplest example of such triggering is in point to point motion, when an external device (such as a camera) needs to begin image acquisition as soon as the move is complete, and the stage is maintaining position within the settling window. In a wide range of other applications (such as pulsing a laser or using a TDI imaging camera), external device triggers must be produced during motion, and at very precise positions. In the simplest case, only a single device trigger is required at a single position in each move; in other applications, repetitive device triggers are required at a fixed position spacing during motion. In more advanced cases, repetitive device triggers are required, but with variable position spacing between them.
The advanced motion controller that is provided inside all SmartStage XY linear positioners offers built in Trigger On Position (TOP) to support applications where synchronization with stage position is required and works with all the potential use cases mentioned above. Key specifications for the triggering include:
- High speed hardware output with < 1 nm resolution for synchronizing stage position with a camera or laser
- The unique motor design combined with ultra-precision Dover Encoder™ provides consistent force over the entire travel of the stage resulting in extremely low velocity ripple while scanning and < 30nm stability at rest
In the example shown in the graph, a single axis translation stage accelerates from rest to a constant velocity. Once the stage settles to its constant velocity, the first trigger is issued at the First trigger position. Successive triggers follow, each separated by a programmed position spacing, until all the triggers have been issued. The stage then decelerates to a rest. Irrespective of the precision of constant velocity motion, the triggers are generated at specific positions of the stage encoder counter, and as a result are precisely positioned relative to the location of the sample.
