Abstract
An optical apparatus includes a light-quantity-adjusting unit, a first lens unit disposed closer to an object than the light-quantity-adjusting unit, a second lens unit disposed closer to an image plane than the light-quantity-adjusting unit, and a drive unit for driving the first lens unit and the second lens unit in an orthogonal-to-optical-axis direction.
Claims1
An optical apparatus comprising:
- a light-quantity-adjusting unit;
- a first lens unit disposed closer to an object than the light-quantity-adjusting unit;
- a second lens unit disposed closer to an image plane than the light-quantity-adjusting unit;
- a holding member holding the first lens unit and the second lens unit;
- a drive unit driving the holding member in an orthogonal-to-an-optical-axis direction;
- a base member movably supporting the holding member in an orthogonal-to-the-optical-axis direction;
- and
- the holding member including:
- a first holder holding the first lens unit;
- a second holder holding the second lens unit;
- a connector connecting the first holder and the second holder along an orthogonal-to-the-optical-axis direction;
- the light-quantity-adjusting unit being inserted and disposed into a space defined by the first holder, the second holder, and the connector, from an orthogonal-to-the-optical-axis direction;
- and
- the light-quantity-adjusting unit being fixed to the base member.
