High-resolution, industrial-grade and cost-optimized

This positioning system for automated confocal microscopy and camera applications enables more than 100 million focalizations and produces excellent images. Especially for confocal optics, smallest positioning steps below one micrometer and minimal deviations from an ideally straight movement are required. A new drive concept consisting of a centrically acting eccentric drive for 100 nm positioning steps meets all industry requirements in terms of robustness, performance, reliability, integration and cost efficiency.

Unaffected by external vibrations for excellent, high-resolution images

Ideal for automated confocal microscopy, analysis and scanning applications

High resolution measurements up to 0.1 µm with confocal sensors, as well as focus stacks with very small stacking distances

Outstanding rigid drive, insensitive to external vibrations for excellent images

Absolutly consistent quality at high throughput of up to 100 mm/s due to extremely robust and durable construction

Very high lifetime and guiding accuracy due to the use of frictionless solid state joints

Cost-optimized and high-precision drive concept consisting of stepper motor, eccentric and gear unit as well as linear measuring system

Optionally expandable:

Adaptable for further traverse paths and different test objects
Position determination of the focus position via a linear measuring system, if required also via an absolute measuring system
Configurable for clean room ISO 14644-1 (up to class 1 on request)
Option to integrate the optics concentrically in the focus axis
Ready-to-use control with pre-configured controller incl. example software

Highest reliability and stability

The measurement of the reached focus position is performed by a linear measuring system, if required also by an absolute one. This results in significantly increased accuracy and immediate availability of the system after switch-on. The eccentric drive realizes very small positioning steps and yet has an extremely stiff drive that is insensitive to external vibrations. Due to the high transmission ratio of the drive, even heavy optics can be used without any problems. The system, which is almost completely symmetrical with few compromises, offers unrivaled low guiding accuracy due to the diaphragm guides with rolling elements.
