Abstract
An optical pickup includes an optical base mounted with at least one optical element, a light source that supplies light incident on the at least one optical element, and a tilt spacer that is disposed between the light source and the optical base to adjust a characteristic of the light that enters the optical base. With the characteristic of the light that enters the optical base adjusted by the tilt spacer, the optical base and the light source are fixed directly to each other.
Claims8
An optical pickup comprising:
- an optical base mounted with at least one optical element;
- a light source that supplies light incident on the at least one optical element;
- and
- a tilt spacer that adjusts a characteristic of the light that enters the optical base, the tilt spacer being disposed between the light source and the optical base,
- wherein with the characteristic of the light that enters the optical base adjusted by the tilt spacer, the optical base and the light source are bonded to each other,
- wherein:
- the tilt spacer has a substantially cylindrical shape;
- the light source is partly inserted into a hollow part of the substantially cylindrical shape of the tilt spacer;
- and
- the tilt spacer includes:
- a light-source-end counterface that faces the light source, the light-source-end counterface being one of two sides of the substantially cylindrical shape;
- an optical-base-end counterface that faces the optical base, the optical-base-end counterface being the other of the two sides of the substantially cylindrical shape;
- a light-source-end projection being a bulging part of the light-source-end counterface, the light-source-end projection rising toward the light source;
- and
- an optical-base-end projection being a bulging part of the optical-base-end counterface, the optical-base-end projection rising toward the optical base.
