Description

The HS20 laser system is suitable for use in harsh machine shop environments with ±1.0 part per million (ppm or µm/m) being achievable for axes lengths up to 60 m.

Features and benefits

Sub-micron resolution – when integrated into the machine feedback system it gives sub-micron feedback at rates up to 2 m/s (depending on configuration).
Non-contact measurement – eliminates the associated errors found in rack and pinion or ball screw feedback systems, such as hysteresis, backlash, mechanical and cyclic errors.
Easy configuration and set up – a single set of dip switches allow for the laser head to be easily configured.

To maintain accuracy over a range of environmental conditions, the HS20 should be used in combination with the RCU10 compensation system, which compensates for the air refractive index changes due to variations in the ambient environment. The RCU10 can also be used to convert a laser wavelength related resolution to a more standard resolution. For example, the RCU10 can be used to convert 633 nm to 1 µm output resolution.
