Abstract: There is provided a camera head for endoscope which enables to achieve a favorable fluorescent image in any wavelength band when the observation is switched over from a normal white-light image observation to an observation of fluorescent images of different wavelength bands.The camera head for endoscope includes a camera-head optical system which includes a spectral prism having a dichroic film which splits light from the endoscope into white light and fluorescent light, and a first image pickup element and a second image pickup element which are disposed in respective optical paths split into two by the spectral prism, and the first image pickup element is for the white-light image observation in which a white-light image is captured, and the second image pickup element is for a fluorescent-image observation in which two fluorescent images of different wavelengths are captured, and the first image pickup element is disposed at a position at which an image is formed in an optical path for the white-light image observation, and the second image pickup element is disposed at a position between two positions at which the two fluorescent images are formed in an optical path for the fluorescent-mage observation, and the camera head for endoscope satisfies the following conditional expression (1). d≦9×P×Fno  (1)

Abstract: An endoscope system includes: an image pickup apparatus in which an insertion portion is detachable, the image pickup apparatus picking up an optical image of light from an observed object; a focus changing section that can change focus of the image pickup apparatus; a control section that generates a control signal to control the optical image in a focused state in a state in which the insertion portion is fitted to the image pickup apparatus; a storage section that stores data associating a type of the insertion portion and control information; an identification section that reads a predetermined code to identify the type of the insertion portion; and an optical characteristic acquiring section that acquires the control information corresponding to the type of the insertion portion identified by the identification section to acquire an optical characteristic of the insertion portion used to generate the control signal.
