Physik Instrumente (PI) has introduced its P-733 XY piezo scanning stage as a high-performance solution for applications requiring ultrafast, nanometer-precise motion, including image stabilization, pixel-shift imaging and resolution enhancement.
The P-733.2 model provides travel ranges of 100µm × 100µm, achieves resolution down to 0.1nm with capacitive sensors, features a zero-play flexure guidance system, and includes a 50mm × 50mm clear aperture designed for transmitted-light applications.
PI also offers the P-733.3 XYZ version of the stage for applications that require an additional Z axis of motion.
The technology enables active image and laser-beam stabilization, pixel shifting, and super-resolution imaging in advanced optical systems by moving the recording area on a defined path with a defined frequency to improve effective resolution without requiring larger sensors or smaller pixels.
This approach addresses limitations of high-resolution imaging chips, where increasing resolution typically involves either enlarging the chip size — requiring larger optics and devices — or reducing pixel size — which decreases light sensitivity and can degrade image quality despite higher pixel counts.
Pixel sub-stepping allows for significant resolution improvement with relatively little effort by shifting the sensor or imaging beam in precise, repeatable patterns to capture multiple sub-pixel samples that are later combined into a higher-resolution image.
The P-733 stage is positioned as a tool for fields such as fluorescence microscopy, white-light interferometry (including OCT in medical technology), surveillance, aerial photography, and digitization of analog materials like technical drawings, art, and paintings.
PI emphasizes its role as a global leader in photonics, piezo, and nanopositioning technologies, leveraging its expertise to deliver stages that meet the demands of advanced optical systems requiring stability and precision at the nanometer scale.
