The Precise Detection Techniques in Optical Lenses Alignment

Abstract

For the high-precision optical lens alignment, the coaxiality of the mechanical axes of the optical components and the lens barrel cannot guarantee good optical performance. As the centering error’s existence of the optical lens, the optical axis of the lens is supposed to be detected to ensure the centering error in required range. The precise detection techniques of mechanical axis and optical axis of the optical component are put forward. Then, the mechanical axis and optical axis integrated precision detection system (MOADS for short) is proposed. Based on the MOADS, the alignment process of optical lenses is put forward.
