L-741 Precision XY Stage
High Travel Accuracy and Stability, 305 × 305 mm Travel Range
- Travel range 305 mm × 305 mm (12'')
- Unidirectional repeatability to 0.05 µm
- Velocity to 90 mm/s
- 2-phase stepper motor or DC motors
- Incremental linear encoder with 1 nm resolution
- Rotary encoder with 20000 impulses/revolution
Highly accurate position measuring with incremental linear encoder
Noncontact optical linear encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement. Optical limit and reference switches. More travel ranges on request.
Crossed roller guide
With crossed roller guides, the point contact of the balls in ball guides is replaced by line contact of the hardened rollers. Consequently, they are considerably stiffer and need less preload, which reduces friction and allows smoother running. Crossed roller guides are also distinguished by high guide accuracy and load capacity. Force-guided rolling element cages prevent cage creep.
Drive types
- 2-phase stepper motor for high torque even at low velocities and higher resolution
- DC motor for high velocity constancy, low vibration, and high velocities

At PI, technical data is specified at 22 ±3 °C. Unless otherwise stated, the values are for unloaded conditions. Some properties are interdependent. The designation "typ." indicates a statistical average for a property; it does not indicate a guaranteed value for every product supplied. During the final inspection of a product, only selected properties are analyzed, not all. Please note that some product characteristics may deteriorate with increasing operating time.

Technologie
Systèmes de guidage classiques
Positioners with travel ranges from several millimeters to one meter usually utilize traditional mechanical guide components such as ball bearings.
Capteurs incrémentaux
PI utilise des systèmes de mesure incrémentaux pour des gammes de déplacements plus longues, à partir d'un millimètre approximativement. Ces capteurs qui, dans la plupart des cas sont des capteurs optiques, offrent une résolution de position de l'ordre du picomètre.
Moteurs électriques rotatifs
Les moteurs électriques rotatifs tels que les moteur DC ou moteurs pas à pas sont utilisés en liaison avec des entraînements à vis.
Positionneurs multiaxes
Les plateformes hexapode sont utilisées pour le positionnement de précision et l'alignement de charges selon six degrés de liberté, trois axes linéaires et trois axes rotatifs.
Applications
Genome Sequencing
Be it in medicine, forensics, or genetics - the genome is the key to new insights for numerous questions. The method known as sequencing-by-synthesis, which used to decipher the genome, has become faster and more precise since it was first developed — the cost has decreased, respectively. The positioning techniques employed in the microscope systems used for this purpose have also contributed to...
Video Endoscopy
Modern medical technology focuses on developing therapies that cause as little discomfort to patients as possible. Endoscopes that allow minimally invasive surgery, make an important contribution to this, for example, in laparoscopy. Especially during medical interventions, the demand for focused and detailed image information is of the highest priority in order to achieve the best possible...
Positionnement de diaphragme adaptatif
In radiation therapy, the individual leaves are adjusted so that the healthy tissue offers the optimum protection from the radiation.
Stabilisation d’image
Fast, piezo-based scanners operate with the necessary velocities in the video frequency range for image stabilization and microscanning.
Pipetage
Piezomotors are suited for pipetting with small devices and sample separations and are able to move the pipettes in the vertical direction.
Tomographie par cohérence optique
Piezo actuators and drives, e.g., PILine® OEM motors, ensure the high precision and position stability required for optical coherence tomography (OCT).
Imagerie par résonance magnétique
Piezo drives are well suited for magnetic resonance therapy, because they are not influenced by strong magnetic fields.
Ophtalmologie
In refractive surgery, high-precision positioning and motion control of the laser are decisive for good results. Piezo-driven stages and tip/tilt mirror systems offer the requested precision, are dynamic and fast and thus additionally help to reduce the treatment time.
