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

Claim 13:
14. A laser microdissection system, comprising:
a laser having a laser beam configured to process a microscopic examination object using tuples of coordinate values which respectively indicate positions of target points on the examination object at least in a first spatial direction and a second spatial direction orthogonal to the first spatial direction,
wherein the laser microdissection system is configured to:
ascertain beforehand positions of at least three reference points at least in each case in the first and second spatial directions and in a third spatial direction orthogonal to the first and second spatial directions, to
define a reference plane based on the positions of the reference points,
determine in each case for the target points further coordinate values indicating an expected position of the target points on the examination object in the third spatial direction as determined further coordinate values,

perform the determination of the further coordinate values depending on the reference plane defined by the position of the reference point(s), and
set a focal position of the laser beam for processing the examination object depending on the determined further coordinate values.
