LENS FRAME, LENS ASSEMBLY AND METHOD OF MANUFACTURING LENS ASSEMBLY

摘要

A lens frame which is configured to dispose a lens on a reference axis and fix the lens, the lens frame includes an axial direction reception section configured to abut the lens in the axial direction and separated from the lens upon fixing of the lens in order to define an orientation of the lens with respect to the reference axis, an adhesive agent guide surface configured to form a gap, and an adhesive agent-blocking section formed between the adhesive agent guide surface and the axial direction reception section in the axial direction, fitted onto the side surface of the lens in the radial direction when the lens abuts the axial direction reception section, and configured to block the adhesive agent such that the adhesive agent introduced into the gap does not flow into the axial direction reception section.

1. A lens frame configured to dispose a lens on a reference axis and fix the lens using an adhesive agent in a state in which a position of the lens is adjusted in an axial direction along at least the reference axis, the lens frame comprising:
an axial direction reception section configured to abut the lens in the axial direction and separated from the lens upon fixing of the lens in order to define an orientation of the lens with respect to the reference axis; an adhesive agent guide surface configured to form a gap through which the adhesive agent is introduced between a side surface of the lens and the adhesive agent guide surface in a radial direction perpendicular to the reference axis; and an adhesive agent-blocking section formed between the adhesive agent guide surface and the axial direction reception section in the axial direction, fitted onto the side surface of the lens in the radial direction when the lens abuts the axial direction reception section, and configured to block the adhesive agent such that the adhesive agent introduced into the gap does not flow into the axial direction reception section.
