A Modular Dispersion Dyeing Microscopic Objective Lens

Abstract

The invention provides a microscopic objective lens capable of modulating dispersion dyeing, which specifically includes: a mirror housing, a dispersion dyeing modulator group installed at the top inside the mirror housing, an optical lens group installed at the bottom inside the mirror housing, and the dispersion dyeing modulator group includes The dispersion dyeing polarizer, the dispersion dyeing analyzer and the regulator, the dispersion dyeing polarizer and the dispersion dyeing polarizer are installed side by side in the regulator up and down, and the dispersion dyeing analyzer is installed directly above the dispersion dyeing polarizer. The adjustable dispersion dyeing microscope objective lens introduces polarization modulation technology, through the light intensity change of linearly polarized light in different polarization states, the transmittance of the central beam is modulated, so as to realize the change of dispersion dyeing intensity, and then qualitative microscopic observation can be realized The micro-property difference trait of an object.

Description

technical field [0001] The present invention relates to a microscopic objective lens, in particular to a method that uses linearly polarized light to show light intensity changes under different polarization states, thereby modulating the change of the central beam transmittance of the microscopic objective lens, so as to form a modulable optical fiber with different dispersion dyeing effects. Dispersion dyed microscope objectives. Background technique [0002] The traditional dispersion dyeing objective lens is loaded with a ring or circular opaque baffle on the rear focal plane of the microscope objective lens. If it is ring-shaped, the central beam will be transmitted; if it is a central circular baffle, the beam can only be transmitted by Permeate around, when the refractive index of the particle and the immersion liquid are different, dispersion occurs, so that the sample image shows different colors, that is, the dispersion dyeing microscopic observation method. The l...

Problems solved by technology

The limitations of traditional dispersion dyeing are: 1. Microscopic objectives of different magnifications must be matched with beam baffles of different geometric specifications; 2. Blocking the beam is completely impenetrable, and the ability of dispersion dyeing is determined by the difference in the refractive index of the sample medium. Therefore, it is difficult to distinguish substances with similar characteristics; 3. It is impossible to qualitatively observe the microscopic characteristics of objects with different characteristics, such as microscopic observation of asbestos

However, the microscope module can only quickly complete the profile measurement, and cannot qualitatively observe the micro-characteristics of the object, and the dispersion dyeing cannot be modulated
