titleOfInvention | Objective lens optical system and the endoscope apparatus that has used it |
abstract | In objective lens optical system, suppress the generation of multiplying power chromatic aberation while wide visual field angle. its constituted mode is, from object side, configure in turn negative first lens group, diaphragm, the second positive lens group, and, first lens group, from object side, configure in turn the signal-lens first lens of negative conduct, and positive lens engaged to the negative joint lens that form with negative lens and be configured, the second lens group, from object side, configure in turn signal-lens the 4th lens of positive conduct, and positive lens engaged to the positive joint lens that form with negative lens and be configured, have again, the formula that satisfies condition (1): 15.0 < vd (RN) < 18.6. wherein, vd (RN) is the Abbe number of the negative lens in the joint lens of formation the second lens group under d line. |
