Abstract: Example embodiments described herein involve a system for testing a light-emitting module. The light-emitting module may include a mounting platform configured to hold a light-emitting module for a camera. The mounting platform may also be configured to rotate. The system may further include a housing holding a plurality of photodiodes arranged in an array over at least a 90 degree arc of a hemisphere. The system may also include a controller configured to control the photodiodes and the rotation of the mounting platform.

Abstract: An ultraviolet optical system includes an objective lens group that captures ultraviolet light for each angle from an ultraviolet light source and forms an intermediate image, and an imaging lens group that re-images the intermediate image. Neither the objective lens group nor the imaging lens group has a cemented surface, and all lenses included in the objective lens group and in the imaging lens group are single lenses that transmit ultraviolet light having a wavelength of 300 nm or shorter. A light distribution measuring apparatus includes the ultraviolet optical system and a sensor, and outputs light distribution of the ultraviolet light source by using a signal obtained by the sensor. The ultraviolet optical system is positioned such that the intermediate image is re-imaged on a light receiving sensor surface, and the sensor has light receiving sensitivity to ultraviolet light having a wavelength of 300 nm or shorter.
