ABSTRACT:
An optical scanning apparatus including a light source, deflection unit configured to deflect a light flux emitted by the light source, a first optical system configured to condense a divergent light flux emitted by the light source, a second optical system configured to focus the deflected light flux on a target scanning face, where the wavelength of the light flux is short, and the first and second optical systems include respective refractive optical elements.
