Abstract

PURPOSE:To easily align optical axes with high accuracy and to obtain the easiness of handling by finding the position projection light from a pinhole provided on the optical axis of an optical lens on the projection side of the holder for the optical lens is maximum. CONSTITUTION:The pinhole 8 is provided on the optical axis of the optical lens 2 on the light projection side of the optical lens holder 3. A semiconductor light emitting element 1, the optical lens holder 3 where the optical lens 2 is incorporated, and a detector 5 is arranged in order and the optical lens holder 3 is moved to find the position where the maximum output light is obtained. The semiconductor light emitting element 1 has the maximum quantity of light on the optical axis 4 in a plane perpendicular to the optical axis 4 of the projection light, so the position where the maximum quantity of light passing through the pinhole 8 of the optical lens holder 3 is obtained to align the optical axes of the both with each other. Consequently, the optical axis 4 of the projection light from the semiconductor light emitting element is easily aligned with the optical axis 7 of a spherical lens with high accuracy.
