The options you need to consider for a dual axis system are:
- Laser source
- Calibration certificate
- RLD10 detector head type for each axis
- Beam output orientation for each axis (not applicable for the differential interferometer head)
A choice of two laser sources are available, RLU10 and RLU20, the latter having improved frequency stability.
Every system undergoes rigorous testing prior to shipment, however system certification is not included as standard. NPL traceable calibration certificates are available as an added cost option which must be ordered at the same time as the system - they are not available retrospectively.
System kits with retroreflector configured detector heads also include retroreflector target optics. For system kits containing plane mirror configured detector heads, Renishaw can, if requested, provide plane mirror target optics. The Accessories section contains information on mirrors, mirror mounts and other auxiliary equipment for use with RLE systems and the HS10 long-range laser scale.
In addition to retroreflector and plane mirror configured detector heads (including the differential interferometer (column reference) head), an RLD10 is available with no internal interferometer. This head allows an RLE system to be used with the linear, angular and straightness optics available from the calibration division. (This detector head is only available with a 0° beam output.)
RLE system manuals contain tables indicating available system configurations for dual axis systems, and identify their constituent parts (for use if ordering any of these components as spares items).
