Abstract

The invention discloses a light source assembly and an observation system for a time difference incubator, and relates to the technical field of biological tissue culture. The light source assembly comprises a first light condensation part, a light attenuation piece is arranged on the light incidence side of the first light condensation part, a plurality of light transmitting parts are sequentially arranged on the light attenuation piece in the length direction of the light attenuation piece, and the light transmittance of the light transmitting parts is sequentially increased in the length direction of the light attenuation piece. The light source assembly is matched with a microcamera to shoot a biological tissue image with stereoscopic impression and layering sense, so that the form of a biological tissue is accurately judged, and the accuracy of evaluation analysis and screening of the biological tissue is ensured. The observation system comprises the light source assembly, a rotating assembly for driving a culture dish to rotate and the microcamera, repeated focusing of a microcamera system can be avoided, the definition of shot images is ensured, the images have the stereoscopic impression and the layering sense, so that the form of the biological tissue is accurately distinguished, and the accuracy of the evaluation analysis and the screening of the biological tissue is ensured.

Description

technical field [0001] The invention relates to the technical field of biological tissue culture, in particular to a light source assembly and an observation system for a jet-lag incubator. Background technique [0002] In Vitro Fertilization (In Vitro Fertilization) refers to the technology in which mammalian sperm and eggs complete the fertilization process in an artificially controlled environment outside the body. It is abbreviated as IVF in English. The existing in vitro culture of human embryos is achieved by placing the culture dish containing the embryos in a time-lag incubator or a conventional carbon dioxide incubator, while ensuring the temperature, humidity and cleanliness of the culture environment. [0003] Among them, the time difference incubator can provide a relatively closed culture and development environment for embryos, close to the mother's uterus, and can realize real-time monitoring and control adjustment of the temperature, CO2 and O2 concentration ...
