Abstract
A device for measuring a horological component comprising a measurement cell, at least two optical systems and a driver unit. The measurement cell comprises a measurement channel filled with a liquid and flat and parallel faces. Each optical system comprises a light emitter suitable for emitting a light in a predefined wavelength so as to illuminate a horological component that is present and being displaced in the measurement channel in the measurement zone and an optical sensor associated with said light emitter to receive at least a part of the light emitted by said light emitter. The optical systems operate in different respective wavelengths. The driver unit drives the optical systems and processes the digital data obtained from the optical systems. It is configured to implement calculations of at least one measurement of a horological component.
