Abstract

The invention discloses a sensing chip clamping and flow control apparatus of a microscopic object lens with a micrometer scale working distance. The apparatus includes a fluid control module, a sensing chip holder, a holder fixing rack, and a three-hole adaptor. The fluid control module is used for controlling a liquid sample to flow in and flow out and for storing the liquid sample, and when thefluid control module and the sensing chip holder are fixed, the bottom of the fluid control module closely presses a sensing chip. The sensing chip holder is used for storing a sensing chip and matches the fluid control module in a close fastening manner, and the holder fixing rack fixes the side of the sensing chip holder. The holder fixing rack is fixed on a moving platform through the three-hole adaptor. Through cooperation of components, rotation of a sensing chip is prevented. The apparatus can be used for a microscopic object lens with a micrometer scale working distance. The apparatusintegrates a liquid control and storage part, and can be directly assembled and disassembled above the microscopic object lens during usage without damaging the lens.

Description

technical field [0001] The invention relates to a sensor chip fixing device for a microscope with a micron-scale working distance and a flow control device in which a sample to be tested is in a gas phase or a liquid phase, and belongs to the fields of photoelectric technology and biomedicine. Background technique [0002] Optical microscopes have great applications in materials, biology, medicine and other fields. With the increase of magnification and numerical aperture, the working distance of the new microscope objective lens is shorter than the traditional low magnification dry microscope objective lens, mostly around tens to hundreds of microns, and the traditional sample fixing device is difficult to meet such requirements. Working distance requirements. Secondly, the clamping device and the fluid control device should have the function of protecting or not damaging the objective lens, such as changing the sample conveniently without causing wear and tear on the lens...
