Linear RLE systems comprise an RLU laser unit and (generally) RLD10 detector head(s) configured for use with retroreflector target optics. Choice of laser unit is very much dependant on operating environment, with the RLU20 being particularly suited to vacuum and controlled environment applications. RLU10 laser units are used within RLE10 systems, and RLU20 laser units in RLE20 systems.
Detector heads are available for use with either 0° or 90° beam output orientations.
Linear solutions can also use detector heads suitable for use with plane mirror target optics. Whilst this will increase output resolution, axis length is reduced to 1 m
