Abstract

The invention relates to a microscope objective lens which is composed of eleven lens bodies. The microscope objective lens comprises four double-bonding-lens sets and three single pieces. The microscope objective lens is provided with the hyper-hemispherical lens body with positive focal power, the positive meniscus lens body with the positive focal power, the biconvex lens body with the positive focal power, the two double-bonding-lens sets with the positive focal power, the first double-bonding-lens set with the negative focal power, the second double-bonding-lens set with the negative focal power, and the third double-bonding-lens set with the negative focal power starting from the object space. The objective lens is moderate in cost, reasonable in process, excellent in imaging quality and capable of meeting the requirement for mass production.

Description

technical field

[0001] The invention relates to optical devices, in particular to a microscope objective lens. Background technique

[0002] At present, the microscope is the most common tool for human beings to understand the microscopic world. In order to better understand the smaller biological and organizational structures, it is necessary to use a microscope objective lens with a large magnification and a large numerical aperture. The optical microscope uses air as the medium, and the maximum numerical aperture can only be close to 1 theoretically. Therefore, in order to increase the resolution and increase the numerical aperture, the medium can be replaced with oil with a refractive index of about 1.5, so that the lens closest to the object side uses a super For a hemisphere, the numerical aperture can be around 1.3. Contents of the invention

[0003] The invention provides a novel microscope objective lens, which solves the problems that the processing of 100x oil ...
