The invention discloses a sample detection device comprising a flow control device, a sample fixing device and an object stage, which are sequentially connected in a matching way. The object stage is disposed at the observation side of a microscopic objective. The flow control device is provided with a center through hole and fluid through holes at the two radial sides of the center through hole, a transparent blocking piece is fixed at the bottom of the center through hole, and the lower part of the flow control device is equipped with an external thread. The sample fixing device is provided with a stepped through hole along the axial direction, the upper end of the stepped through hole is a connecting hole, the connecting hole is equipped with an internal thread matching the external thread, the lower end of the stepped through hole is a mounting hole, and the bottom of the mounting hole is equipped with a retainer ring for placing a sample. The lower end of the exterior of the sample fixing device is provided with an extending section. An axial through hole of the object stage is provided with a carrier flange extending inward. The extending section is used for extending the carrier flange. According to the invention, the working distance between the sample and the microscopic objective is shortened, liquid detection and sample replacement are convenient, and the microscope objective is not damaged.
Description
technical field [0001] The invention relates to the fields of optoelectronics and biomedicine, in particular to a sample detection device and a microscope objective lens detection system that can be used for an ultra-short working distance microscope. Background technique [0002] A microscope is an instrument that can magnify tiny objects to the point where the naked eye or a detector can distinguish them. It has great applications in the fields of materials, biology, and medicine. With the increase of magnification and numerical aperture, the working distance of the current new type of microscope objective lens is greatly reduced compared with the traditional low magnification non-oil immersion objective lens, and most of them are about a hundred or even tens of microns. Therefore, the traditional sample fixing device It is difficult to meet the requirements of the working distance at the micron scale. Especially with the development of various new breakthrough diffractio...
