METHOD FOR MANUFACTURING OPTICAL DEVICE, AND OPTICAL DEVICE

PROBLEM TO BE SOLVED: To provide an optical device wherein a focal point of a lens can be adjusted to an optional position. SOLUTION: The method for manufacturing the optical device including an optical element, a translucent member which has two surfaces non-parallel to each other and whose one surface of the two surfaces comes in contact with the optical element and the lens coming in contact with the other surface of the two surfaces of the translucent member and optically bonded to the optical member via the two surfaces of the translucent member, includes a step of adjusting a distance between the lens and the optical element by moving the translucent member to both of the optical element and the lens while the optical element, the translucent member and the lens are brought into contact with each other.
