N-725: New objective scanner with piezo stepping drive for 3D stacks with up to 1 mm depth

N-725: New objective scanner with piezo stepping drive for 3D stacks with up to 1 mm depth

New microscopy methods, such as two-photon microscopy, make it possible to record 3D stacks with up to 1 mm depth in biological samples. For this they require high-performance drives for positioning the objectives.

PI (Physik Instrumente) now developed the new N-725 PIFOC® objective scanner with piezo stepping drives especially for position-ing microscopy objectives. The N-725 provides travel ranges of up to 2 mm along the optical axis. At the same time the technology allows rapid positioning:
The new focusing system achieves settling times of around 20 milli-seconds for 3 µm steps. It has an extremely compact design and is no larger than conventional, piezo-based PIFOC® objective stages.

The focal plane can easily be changed with a single mechanical system thanks to the combination of high resolution and long travel ranges. Therefore, there is often no need for a combined Z-positioning of the objective, e.g. with stepper motor and additional piezo stages.

Piezo Stepping Drive – the Multi-Functional Piezo Linear Motor
The NEXACT® piezo stepping drive advantageously combines the best characteristics of piezomotor principles in a compact unit: High resolution, high force and high speed. The feed motion is achieved solely via the nanometer-accurate motion of clamped piezo actuators – wear-free, high resolution and with controllable speed.
In stepping mode, high positional resolutio
n and high drive force can be achieved over the full travel range. Additionally, the high stiffness allows fast oscillations of 7 micrometer amplitude and resolutions to 30 pm (analog operation, open-loop).

At the target position, the drive is self-locking, requires no current and consequently generates no heat. The position is stable in the nanometer range so there is no jitter about the target position.

Physik Instrumente (PI) has introduced the new LPS-24 series. At only 24 × 33 × 20 mm³, these new miniature positioning stages provide a travel range of 15 mm with nanometer-precision resolution. The LPS-24 stages fulfil important requirements for the positioning of optical or mechanical components or for the adjustment and manipulation of samples in application environments with a confined space. For the LPS-24 series, PI uses NEXACT® piezo stepping drives. These
Modular Hexapod System for Fast, Economic and Precise Positioning
PI presents a modular concept for six-axis positioning systems. Due to its modularity, the high-precision parallel kinematics can be adapted fast and efficiently to customer requirements. The six identical Hexapod struts are designed such that their length can be easily scaled. They include the required electronics for reference point switches, limit switches, position sensors and electronic commutation for the brushless DC motors. Their standardized joints allow to combine them with almost

Compact, Digital Motion Controller for Nanopositioning
The single channel E-709 piezo controller from Physik Instrumente (PI) has been already introduced for piezo-based positioners and scanners which use strain sensors. Since the majority of the nanopositioning systems from PI employ such sensors, the E-709 allows significantly lower system costs in comparison to the digital controllers offered up until now. The biggest differences between the digital and analog controllers are that you can influence all parameters directly through calculation
They Go Through it With a Fine-Tooth Comb: PIFOC® Piezo Drives for Objectives
More and more techniques in microscopy, today, require an improved resolution. This often requires the combination of a large numerical aperture of the objective, that is a large clear aperture, and a large working distance along the optical axis. 3D images of living tissue are then possible, for example with the help of two-photon spectroscopy. For this purpose, PI now offers a PIFOC® piezo Z-drive for objectives with a clear
