Problems solved by technology

However, limited by the size of a single field of view and the stitching algorithm of the field of view, the whole-film imaging speed is slow, and it takes several minutes to complete the whole-film scanning imaging

Embodiment Construction

[0071] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0072] see figure 1 , is a schematic diagram of the structure of the microscope objective lens 10 provided by the embodiment of the present invention, including: fourteen spherical lenses arranged on the same optical axis, and the fourteen spherical lenses include in sequence from the object side to the image side: a first lens (L1) , the second lens (L2), the third lens (L3), the fourth lens (L4), the fifth lens (L5), the sixth lens (L6), the seventh lens (L7...

Abstract

The present invention provides a microscope objective lens. The microscope objective lens comprises 14 sheets of spherical lenses which are arranged in a coaxial mode. The 14 sheets of spherical lenses comprise in order from an object side to an image side: a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), a seventh lens (L7), an eighth lens (L8), a ninth lens (L9), a tenth lens (L10),an eleventh lens (L11), a twelfth lens (L12), a thirteenth lens (L13) and a fourteen lens (L14). The microscope objective lens obviously increasesthe view field of the object side while ensuring the high numerical aperture and the high resolution to achieve apochromatism from 500nm to 800nm, greatly eliminates spherical aberration, coma, astigmatism, field curvature, distortion, chromatic difference of magnification and axial chromatic aberration, meets the flat field apochromatism objective lens demand and achieves the technical demand ofa wide field of view (namely a large visual field number and a low range) and a high numerical aperture.

Description

technical field [0001] The invention relates to the technical field of microscopes, in particular to a microscope objective lens and a microscope. Background technique [0002] Microscopic objective lens completes its specific imaging function with a certain field of view, focal length, and relative aperture, but limited by the principle of optical imaging, these optical characteristic parameters are mutually restricted. Microscopic objective lenses have the characteristics of large numerical aperture and high resolution. However, limited by the ability of the optical system to collect information, it is usually difficult to balance high resolution and large field of view at the same time. The field number (F.N.) of the conventional microscope objective lens is 22mm, which cannot meet the requirements of large-area or even full-slice imaging. The existing technologies all adopt the method of fast scanning and field of view stitching to realize full-slice imaging. However,...
