Abstract
An optical pen for use in a chromatic range sensor (CRS) may be used in a probe system for a coordinate measuring machine (CMM). The optical pen includes a confocal optical path, an interchangeable optics element, an optical pen base member, and a repeatable fast exchange mount. The confocal optical path includes a confocal aperture and a chromatically dispersive optics portion. The interchangeable optics element includes the chromatically dispersive optics portion. The optical pen base member includes an external mounting surface for mounting to an external reference frame. The repeatable fast exchange mount includes a first mating half located on the base member and a second mating half located on the interchangeable optics element. The repeatable fast exchange mount is configured to allow the base member to receive and hold the interchangeable optics element in a fixed relationship relative to the base member and the external reference frame.
