Abstract
An holding device can hold an optical component and a masking component with high precision in a simple configuration and a limited space. A first holding member includes a first receiving face that is in contact with a first optical component in an optical axis direction to fix a position of the first optical component in the optical axis direction and a second receiving face that is in contact with a second optical component in the optical axis direction to fix a position of the second optical component in the optical axis direction.
Claims11
A holding device comprising:
- a first optical component which holds a first lens;
- a second optical component which holds a second lens;
- a first elastic member arranged at a position between the first optical component and the second optical component in an optical axis direction,
- a first holding member, and
- a second holding member,
- wherein the first holding member and the second holding member press and hold the first optical component, the first elastic member, and the second optical component in the optical axis direction, and
- wherein the first holding member includes,
- a first receiving face that is in contact with the first optical component in the optical axis direction to fix a position of the first optical component in the optical axis direction, and
- a second receiving face that is in contact with the second optical component in the optical axis direction to fix a position of the second optical component in the optical axis direction.
