1.1 Linear Long-travel Translation Stage
1.1.1 Introduction
The TravelMax single-axis linear long travel stage has been designed to integrate seemlessly into the Thorlabs modular
electronic or benchtop nanopositioning systems, with the added functionality of encoder validated position reporting.
The APT Server includes full support for encoded position feedback. We manufacture a number of linear encoded equipped
stage/actuator combinations with associated electronics and cabling in order to connect to the APT range of stepper controller
units (both bench top and modular rack variants).
Combining the TravelMax stage with an integrated optical encoder provides the ideal solution for when stability, long travel
and high load capacity need to be coupled with absolute position accuracy. The TravelMax LNR502E features a sub-micron
resolution position linear scale that is attached to the moving platform of the stage. The encoder reads this scale to provide
the feedback to ensure true nanopositioning capabilities. This means that mechanical positioning errors, such as backlash,
can be ignored.
This combination of long-travel actuator and a high-precision optical encoder provides solutions to applications such as
manipulation, alignment and assembly of photonics products, and microscope examination of large samples.
