摘要:
A zoom lens includes a first lens group including an optical path change member that changes an optical path, a second lens group including at least one negative lens and at least one positive lens, and lens groups having a positive refractive power. The first lens group is closer to an object side of the zoom lens and is fixed relative to an image plane during a zooming operation. The second lens group is adapted to move during the zooming operation. Each of the lens groups includes at least one positive lens, and the lens groups are closer to an image plane side of the zoom lens. The zoom lens satisfies vdLP>71, vdL2p 1.71, wherein “vdLP” is an Abbe number, “vdL2p” is an Abbe number, and “ndL2m” is a refractive index.
摘要(中):
变焦透镜包括包括改变光路的光路改变部件的第一透镜组,包括至少一个负透镜和至少一个正透镜的第二透镜组以及具有正折光力的透镜组。 第一透镜组更靠近变焦透镜的物体侧,并且在变焦操作期间相对于像平面固定。 第二透镜组适于在变焦操作期间移动。 每个透镜组包括至少一个正透镜,并且透镜组更靠近变焦透镜的像面侧。 变焦透镜满足vdLP> 71,vdL2p <40,ndL2m> 1.71,其中“vdLP”是阿贝数,“vdL2p”是阿贝数,“ndL2m”是折射率。
