Abstract
Provided is a narrow beam generation device capable of generating a narrow beam having a predetermined diameter or less at an arbitrarily defined position on the basis of light emitted from an arbitrarily defined light source. This narrow beam generation device comprises a beam shaping means for shaping a line light source. The beam shaping means has a light gathering part, the line light source is disposed on the optical axis of the light gathering part, and the center position on the optical axis of the line light source is disposed at a position more distant from the light gathering part than the focus position of the light gathering part.
Claims7
A narrow beam generation device comprising:
- a beam shaper configured to shape a beam emitted from a line light source,
- the beam shaper comprising a condenser,
- the line light source being arranged on an optical axis of the condenser, and
- the line light source having a center position on the optical axis arranged at a position farther from the condenser than a focal position of the condenser.
