Positioning holding accuracy in a nanometer range

This highly stable assembly system for high-precision lasers consists of an 8-axis positioning system and a substructure designed for ISO 5 cleanroom conditions and UV compatibility. It has two independently operating processing heads (Y1, Y2, Z1, Z2, Phi1, Phi2) on a common X-axis. The Phi axes are mounted on the Z axis. This allows 2 components to be positioned exactly in space in relation to each other and held stable over a long period of time in a currentless, uncontrolled standstill.

This system was developed for the assembly of a laser for the Fraunhofer ILT. The institute has designed a laser for measuring the methane concentration in the atmosphere, which will be used in the German-French satellite Merlin in 2021/2022. 

 

Specially developed for the assembly of miniaturized components

Maximum accessibility for highly sensitive assemblies

This system is available for construction spaces of 600 x 400 x 200 mm³. The workspace in which positioning is to take place is defined as 430 x 220 x 100 mm³ and allows 180° swiveling without colliding with the positioning system (free travel).

The extreme stability is achieved by the combination of weight, use of air bearings and strong AC servos as well as ball screws. In addition to the solutions developed specifically for this special task, PMT160 precision linear stages were used for the Z axes and DT130 from our product portfolio for the rotary axes (Phi). All of the eight axes are driven and positioned by stepper motors. The positioning system complies with the required specifications and has passed all of the customer's acceptance tests with top marks.

Individual extensions and customizations
