Abstract: A method and a system (13) for evaluating a lower filter part (2) of a cavity filter including a bottom plate from which wall portions and at least one resonating element extend in an upward direction, wherein the method comprises: —scanning the lower filter part using a laser scanning assembly (14) to collect data relating to shapes and dimensions of the lower filter part, —comparing the collected data with reference data to determine whether the lower filter part fulfils predetermined quality requirements. A method for manufacturing a cavity filter includes evaluating a filter body of the lower filter part prior to assembling the cavity filter, wherein the step of assembling the cavity filter is only carried out if the filter body fulfils the predetermined quality requirements.
