Amplified Piezo Stage for Microscope Slides![]()
LPSA1 Microscope Slide Holder Application Idea The LPS710E(/M) can be used to scan slides using a Cerna® microscope. LPS710E Piezo Scanning Stage ![]() Please Wait ![]() Click to Enlarge The LPS710E/M stage and LPSA1/M slide holder attached to the MP100 Rigid Stand for use with a Cerna® microscope.

The LPS710E(/M) Amplified Piezo Stage provides long range, fine focus Z-axis travel for a microscope slide while maintaining a compact, low-profile footprint. It features submicron repeatability, nanometer positioning resolution, low angular error, and fast millisecond response and settling times. When used with the LPSA1(/M) microscope slide holder, the stage is ideal for imaging modalities requiring sensitive sample positioning and sectioning, such as confocal laser scanning microscopy. This stage is not compatible with trans-illumination. The stage is driven by a discrete piezo stack housed within a hardened steel flexure structure that preloads the piezo stack and amplifies its displacement. When controlled in a closed loop, which provides higher precision positioning and reduced hysteresis, this results in a maximum total displacement of 800 µm; when operating in open-loop, the resulting maximum total displacement is 1100 µm. Built-in capacitive feedback sensors along with our high-precision piezo controller provide 6 nm resolution in closed-loop operation, enabling active compensation for short- and long-term drifts. When used in open loop, the controller will provide an accurate readout of the stage position with a resolution of 2 nm. An engraved arrow on the side of the unit indicates the direction of travel. For additional information on piezoelectric device structure and actuation, see the Piezoelectric Tutorial. The LPSA1(/M) slide holder uses two countersunk cap screws to attach to the 21.0 mm x 21.0 mm mounting surface on the top of the LPS710E(/M). The mounting surface is equipped with four 4-40 (M3) blind mounting holes that are 4.8 mm deep to orient the slide holder in two orthogonal positions on the stage. The slide holder is compatible with microscope slides and test targets, as well as any rectangular optic from 2.88" (73.1 mm) to 3.00" (76.5 mm) long and up to 0.055" (1.4 mm) thick and 1.00" (25.4 mm) wide. Slides are secured using the red, spring-loaded plunger. In addition to the slide holder, the stage can secure a Ø7 mm optic mount or other 4-40 (M3) equipped component. The base of the stage includes two slots for 1/4"-20 (M6) cap screws and two slots for 4-40 (M3) cap screws that can be used to secure the stage to a stage or breadboard for use with a microscope, such as our Rigid Stands or Translating Platforms, or directly to an optical table. In addition, the stage has two bottom- and side-located 4-40 (M3) mounting holes that can be used to secure the stage using our line of mini-series components. Each stage is shipped with a piezo controller that has been factory calibrated to the specific stage to achieve maximum accuracy. It is not recommended to operate the piezo stage with a different controller. Piezo control is supported through the included Kinesis and APT GUIs, our ThorImage®LS image acquisition software, an externally supplied control voltage, or the MZF001 Joystick Console (sold separately below). See the Software & External Control tab for more details. The controller offers USB and RS-232 interfaces for computer control; a BNC input for sine, sawtooth, and square wave drive signals; a BNC output that gives either positioning feedback from the scanner's built-in capacitive sensors or a signal proportional to the piezo drive voltage; and a connector for the MZF001 joystick. In addition, a DB15 connector provides signals that can be used for synchronization with external equipment.

In addition, a DB15 connector provides signals that can be used for synchronization with external equipment. Complete details on control are available in the LPS710E manual for Kinesis and APT (PDF links). Open-Loop Operation vs. Closed-Loop Operation In closed-loop operation, which supports a travel range of 800 µm, the user directly controls the stage displacement (in µm). The built-in capacitive feedback sensors measure the stage displacement with 6 nm resolution in closed-loop operation.

The default settings are designed to provide stable operation, but manually fine tuning the PID loop and notch filters helps account for the specific objects mass in use in the experiment, reducing positional overshoots and ringing about the commanded objective position. Screenshots are shown to the left. ThorImageLS Image Acquisition Software The ThorImageLS software works in conjunction with the Kinesis GUI, so the settings for the IO Control Mode should be set to 'Software + External BNC' before controlling the stage. Externally Supplied Control Voltage The external input BNC connector is typically used with sine, sawtooth, or square drive signals. The maximum frequency of the signal that should be applied depends upon the waveform. For large periodic waveforms (i.e., sine waves that provide >200 µm of total displacement), the recommended drive frequencies are:
For staircase waveforms with step sizes up to 50 µm, the minimum time between steps can be as small as the 25 ms typical settling time. MZF001 Joystick Console DB15 Connector Piezo Controller Pin DiagramsStage Connector
