Abstract
A system and method for a chromatic probe detachment sensor is provided. A detachment signal element is included in an interchangeable optics element of a probe. The detachment signal element is configured to substantially transmit a first set of wavelengths corresponding to a measuring range, and at least partially reflect a set of detachment element wavelengths. In one implementation, the detachment signal element comprises a thin film coating such as a sharp edge filter. The detection of a detachment condition can thus be achieved using the existing probe electronics without requiring the addition of other external sensors or wiring to the probe or coordinate measuring machine that utilizes the probe. The sensing of a detachment condition may be utilized to halt further movement of the probe to minimize damage in the event of a collision.
