Laser interferometers offer the ultimate in high accuracy, repeatable and traceable measurement, using externally mounted optical components.

There are two Renishaw laser interferometer systems in use worldwide, the XL-80 (in production since 2007) and the system that it replaced, the ML10 (1988 - 2007).

AxiSet Check-Up

Compatible with common formats of 5-axis and multi-tasking machines, AxiSet Check-Up provides machine users with a fast and accurate health check of rotary axis pivot points. Alignment and positioning performance checks are carried out rapidly to benchmark and monitor complex machines over time.

A great addition to existing laser calibration and rotary axis angular rotation performance checking systems (XL-80 and XR20-W).

RSU10 system

The XL-80 laser system offers the ultimate for portable ultra accurate laser measurement. However there may be applications where the requirements for shop floor, portable use are not required but a more compact system would be advantageous, e.g fixed test bench application.

Using the RLE laser interferometer system as a basis, a special RSU10 interface allows full access to XL-80 software including LaserXL and QuickViewXL dynamic software. The small remote detector heads of the RLE laser give great flexibility for installation on test rigs. A further benefit is that the heat source (laser) can be located away from the test rig, a good metrology practice. (Maximum linear range typically 4 m and maximum travel velocity 1 m/s.)
