Assignee: LEICA MICROSYSTEMS CMS GMBH
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 14:
15. A method for calibrating the light source module according to claim 1, comprising:
emitting the illumination light by means of the light source along the illumination light path with the at least one light blocking shutter being moved out of the illumination light path,
detecting the intensity of the illumination light propagating along the illumination light path by a reference light sensor,
varying a power supplied to the light source until the intensity of the illumination light detected by the reference light sensor is equal to a predetermined reference intensity,
storing a value of the power, at which the illumination light detected by the reference light sensor is equal to the reference intensity, as a reference power value,
moving the light blocking shutter into the illumination light path and measuring the intensity of the illumination light emitted, which is emitted by the light source at the reference power value, by the light sensor integrated with the light blocking shutter as a reference intensity value, and
determining a calibration characteristic based on the reference power value and the reference intensity value.
