OPTICAL DEVICE AND METHOD OF ASSEMBLING THE DEVICE

摘要

An optical device and a method of assembling the device, the device comprising a substrate (5) and a lens (Ls) installed on the substrate (5); the method comprising the steps of sticking a holder (51) onto the substrate (5) with UV adhesive agent (52) and fixedly sticking the lens (Ls) onto the holder (51) with the UV adhesive agent (53), the lens (Ls) is held by a holder (57) fitted to the tip of the arm (56) of an adjusting jig (55), adjusting the position of the lens (Ls), and radiating ultraviolet ray to the UV adhesive agent (53) to cure the UV adhesive agent to fixedly adhere the lens (Ls) at a desired position, whereby optical elements can be easily fixed onto the substrate in proximity to each other, and the size of the device can be easily reduced.
