Abstract
The present disclosure provides an optical system that includes a prism having an incident surface, an exit surface, and one or more reflecting surfaces. A first intermediate imaging position of a light flux in a first direction is located inside the prism. The first intermediate imaging position is different from a second intermediate imaging position of the light flux in a second direction orthogonal to the first direction.
Claims25
An optical system comprising:
- a prism having an incident surface, an exit surface, and one or more reflecting surfaces;
- and
- a laser element configured to emit a laser light to the incident surface of the prism, wherein
- a first direction is a long diameter direction of a pupil diameter of the laser light emitted from the laser element,
- a second direction is a short diameter direction of the pupil diameter of the laser light emitted from the laser element,
- the first direction and the second direction are orthogonal to each other,
- a first intermediate imaging position of a light flux of the laser light in the first direction and a second intermediate imaging position of the light flux of the laser light in the second direction different from the first intermediate imaging position are located inside the prism, and
- the second intermediate imaging position is located closer to the incident surface than the first intermediate imaging position.

- a second direction is a short diameter direction of the pupil diameter of the laser light emitted from the laser element,
- the first direction and the second direction are orthogonal to each other,
- a first intermediate imaging position of a light flux of the laser light in the first direction is located inside the prism, and
- the pupil diameter of the laser light in the second direction gradually increases without forming an intermediate image of the light flux of the laser light in the second direction.

An optical system comprising:
- a prism having an incident surface, an exit surface, and one or more reflecting surfaces, wherein
- a first intermediate imaging position of a light flux in a first direction and a second intermediate imaging position of the light flux in a second direction different from the first intermediate imaging position are located inside the prism, the first direction being orthogonal to the second direction, and
- the second intermediate imaging position is located closer to the incident surface than the first intermediate imaging position, so that an optical magnification in the second direction is larger than an optical magnification in the first direction.
