| description | The invention relates to a microscope objective lens which comprises a first lens group (T1) with positive focal power, a second lens group (T2) with positive focal power and a third lens group (T3) with negative focal power which are sequentially arranged from an object side to an image side along an optical axis. The third lens group (T3) comprises a double-Gaussian structure composed of two optical elements. The microscope objective lens has the advantages of large field of view and large numerical aperture.
本发明涉及一种显微镜物镜，包括沿光轴从物侧至像侧依次排列的具有正光焦度的第一透镜群(T1)、具有正光焦度的第二透镜群(T2)和具有负光焦度的第三透镜群(T3)，所述第三透镜群(T3)包括一个由两个光学元件组成的双高斯结构。本发明的显微镜物镜具有视场数大以及数值孔径大的优点。 |
