Handheld or portable confocal microscope objectives

Abstract

A handheld or portable confocal microscope objective includes: a housing; an infinite conjugate objective assembly disposed within the housing; a protective window connected to the end of the housing and having a contact surface and a protective window compression surface oppositely disposed therebetween, the contact surface being for contacting the sample to be tested, and the protective window compression surface being located between the contact surface and the compression surface of the objective assembly at one end of the infinite conjugate objective assembly; an optical coupling agent filling the space between the infinite conjugate objective assembly and the protective window, and being tightly abutting the compression surfaces of the objective assembly and the protective window, the optical coupling agent having a fixed refractive index; and an objective drive module connected to the infinite conjugate objective assembly, the objective drive module driving the infinite conjugate objective assembly to move, thereby adjusting the degree of compression of the optical coupling agent. The handheld or portable confocal microscope objective of this invention enables deep, high-resolution, non-invasive three-dimensional tomographic imaging.
