Description

Optical microscope multi-sample clamping device

Technical Field

The utility model belongs to sample clamping device field, more specifically relates to an optical microscope multiple sample clamping device.

Background

Light sheet illumination microscopy is currently gaining wide attention from various researchers in the international world as an emerging leading edge imaging method in the twenty-first century. The light sheet microscopic imaging system has the characteristics of high axial resolution, higher flux, low photobleaching and the like, and is widely concerned in the field of biomedical imaging. Compared with the traditional fluorescence microscopic imaging, the light sheet fluorescence microscopic system adopts an additional illumination light path to generate a layer of extremely thin laser light sheet. When the sample is placed in the light sheet working area, only the plane through which the thin light sheet passes can excite a fluorescence signal, and the fluorescence signal is collected by a wide-field collecting light path which is orthogonal to the illumination light path to form an image. A series of section fluorescence image sequences can be generated by rapidly scanning a sample or an optical sheet in the detection optical path direction, namely the z direction, and the three-dimensional structure of the sample is reconstructed by stacking.

In the light sheet microscopic imaging system, a sample needs to be fixed in the imaging system through a clamping device, and the clamping device serves as a part of the imaging system, so that an illumination light path and a detection light path are not shielded on the premise of stably clamping the sample. In general, whether in vivo or ex vivo imaging, the sample must be fixed in an optically clear medium or immersed in an index-matching solution, or aberrations and distortions can be introduced.

When the traditional single-sample clamping technology faces a multi-sample large-scale imaging scene, each sample needs to be sequentially loaded, repeated sample loading can reduce imaging efficiency and limit imaging flux, and for different biological samples, due to different volumes and the like, a single clamping piece cannot be compatible with biological samples of various sizes, so that the imaging efficiency is low; in the prior art, only one sample can be clamped at each time, the clamping of a plurality of single samples cannot be accommodated and used simultaneously due to the limitation of the volume of a sample cavity, an optical microscope multi-sample clamping device is urgently needed, and switching among different biological samples can be realized, so that the optical microscope multi-sample clamping device is suitable for a multi-sample large-scale high-efficiency imaging scene.
