System and method for measuring concentricity of laser to cap

摘要

A device and method is disclosed for passively checking the concentricity measurement of optical components in an optical assembly. The optical assembly includes a package for a photonic device which has a header and a lens cap having an integrated lens. The photonic device is mounted to the header. A display system can be used to view the photonic device through the lens of the cap. Using a camera with a high magnification lens integrated into the display system, the alignment between the photonic device and the lens in the cap is measured.
