<p>PROBLEM TO BE SOLVED: To provide an imaging apparatus in which color shift due to chromatic aberration can be lessened easily. SOLUTION: The imaging apparatus comprises a light source system 10, a light transmission system 12, an optical modulation system 14, an optical focusing system 17, and a color filter 11 wherein images of different colors are formed on a recording medium by an identical optical recording system by varying the transmission wavelength of the color filter 11 sequentially. Optical axis of the optical focusing system 17 is inclined with respect to the vertical direction of a recording medium 4 and positional shift of recording incident to carriage of the recording medium 4 is lessened utilizing the fact that the focus position is different delicately for respective wavelength due to chromatic aberration.</p> |
