Claim 10:
11. A method for determining a performance metric of an optical receiver assembly comprising:
aligning, using one or more adjustable alignment stages, the optical receiver assembly comprising one or more lenses in an optical path downstream from an illumination assembly comprising a light source and one or more optical elements arranged to direct a beam of light from the light source along the optical path, the one or more optical elements including a parabolic mirror, wherein aligning the optical receiver assembly comprises focusing the beam of light from the light source of the illumination assembly to an image plane of a sensor of the optical receiver assembly;
selecting a first light intensity for the light source from a plurality of different light intensities, wherein selecting the first light intensity of the plurality of different light intensities from the light source comprises attenuating the beam of light from the light source using a neutral density filter;
exposing the optical receiver assembly to the beam of light from the light source at the first light intensity;
capturing image data by the sensor of the optical receiver assembly while exposing the optical receiver assembly to the beam of light at the first light intensity; and
determining, based on the captured image data, the performance metric for the optical receiver assembly.
