AI Technical Summary

Technical Problem

During imaging of live animals, external screen light enters the microscope detector through the objective lens, affecting the image quality and exceeding the upper limit of light intensity that the detector can withstand, resulting in imaging failure.

Method used

An objective lens hood for imaging live animals is designed, including a first lens hood and a second lens hood, which are installed on the objective lens and the animal respectively. Through the matching styling design, external light cannot enter the objective lens and ensure the imaging quality.

Benefits of technology

It effectively reduces the movement interference of living animals, simplifies the installation process of the light shield, and ensures that external light does not enter the objective lens during imaging, improving the imaging quality.

Abstract

The utility model provides an objective lens light shield for living animal imaging, which comprises a first light shield and a second light shield, the first light shield is arranged on an objective lens, and the window of the first light shield is larger than the lens diameter of the objective lens; the second light shield is arranged on an animal to be imaged, and a window of the second light shield is larger than an imaging part of the animal; the shape of one end of the first light shield away from the objective lens is matched with the shape of one end of the second light shield away from the to-be-imaged animal. According to the utility model, through cooperation of the two shading structures, external screen light cannot enter the objective lens, so that imaging quality is ensured, and the problems that screen light in imaging is collected through the objective lens and enters a microscope detector, image quality is affected and even the light intensity upper limit bearable by the detector is exceeded, and imaging quality is affected are solved. And normal imaging cannot be carried out.
