Assignee: NOVA LTD.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An optical measurement system that comprises:
i. optics, wherein the optics comprise an illumination path and a collection path;
ii. a Raman detector;
iii. at least one adjustable spatial filter positioned upstream to the Raman detector; and
iv. a controller that is configured to generate or receive at least one filtering parameter of a spatial filtering process that is applied before a Raman detector; and
v. wherein the optics are configured to acquire Raman spectrums of multiple sites of the sample while applying the at least one filtering parameter;
wherein the optics comprises a rotatable wedge prism, wherein the controller is configured to control a rotation of the wedge prism to find an orientation of the wedge prism that once applied will direct an impinging beam generated by the optical measurement system through a compensating path of propagation of the impinging beam.
