Assignee: KABUSHIKI KAISHA NIHON MICRONICS
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A measurement method of receiving, on an incident end surface of an optical probe, an emission light output from an optical semiconductor element, the method comprising:
setting a gap between the optical semiconductor element and the incident end surface to a predetermined working distance;
shifting a relative position between the optical semiconductor element and the optical probe on a plane surface intersecting with and perpendicular to an optical axis of the emission light to measure an incident intensity of the emission light at a plurality of different shifted positions, resulting in a plurality of measured incident intensities corresponding to the plurality of different shifted positions, wherein the shifting is performed while keeping the predetermined working distance constant; and
obtaining an incident intensity pattern from the plurality of measured incident intensities, the incident intensity pattern showing a relationship between a change in the relative position and the respective plurality of measured incident intensities.
