Definitions
- a laser beam emitted from a semiconductor laser element for collimating or converting a divergent laser beam to a collimated laser beam is used.
- a lens system (particularly a collimated lens when collimated) is used.
- This lens system is a glass lens element with a small refractive index change with temperature. It is common to use
- Japanese Patent Application Laid-Open No. H04-328512 discloses a method in which a laser light source is combined with a lens having a diffractive action to focus on a lens. A method has been proposed to reduce the deviation of the imaging position due to temperature changes by fixing the distance.
- the laser beam emitted by the device is imaged by the first imaging optical system that forms a linear image extending in the main scanning direction near the deflection surface of the optical deflector, and the first imaging optical system
- a second imaging optical system including a scanning lens for re-imaging the laser beam as a spot on the surface to be scanned, and the light source device emits a divergent laser beam.
- FIG. 3 is a schematic configuration diagram of a light source device according to Embodiment 4 of the present invention.
- the emitted light from the semiconductor laser 41 is emitted as substantially parallel light by the single-lens element 42 according to the first embodiment.
- single-lens element 42 has a configuration equivalent to the single-lens element described in the first embodiment.
- the semiconductor laser 41 and the single-lens element 42 are respectively fixed to a base 43.
- the base 43 has a V-shaped groove 44 for fixing the lens. 2 can be adjusted back and forth on the V-groove 4 4 to adjust the collimation.After the adjustment, the contact portion 45 between the lens side surface and the V-groove can be adjusted with an adhesive.
- the lens can be fixed.
- the present invention is suitable for a light source device included in a scanning optical device such as an LBP, and a light source device for an optical disk device such as a CD (CompactDsk) or various DVDs.
- a scanning optical device such as an LBP
- a light source device for an optical disk device such as a CD (CompactDsk) or various DVDs.
