MANUFACTURING METHOD OF OPTICAL ASSEMBLY AND DESIGNING METHOD OF A LENS TO BE ASSEMBLED |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical assembly capable of achieving satisfactory optical characteristics without adjusting assembling position.SOLUTION: The manufacturing method of an optical assembly includes: a first assembling step S1 in which lenses from a first lens to a n-1-th lens (n is an integer of 1<n≤N) are assembled with a lens holding member to build a pre-assembly; an optical characteristics measurement step S2 in which optical characteristics of a first optical system in the pre-assembly are measured; an optical parameter correction value calculation step S3 in which a deviation amount from a design value of the optical characteristics of the first optical system is calculated based on the measurement result of the optical characteristics and a correction value of an optical parameter of the n-th lens is calculated by changing at least the optical parameter of the n-th lens from the design value; a lens manufacturing step S4 in which the n-th lens is manufactured based on the correction value; and a second assembling step S5 in which the n-th lens manufactured in the lens manufacturing step S4 is assembled into the pre-assembly. |
