Problems solved by technology

[0002] Traditional detection, research, and diagnosis based on pathological slices are all done by placing pathological slices on the microscope stage, observing and taking pictures through manual operation. The traditional microscope observation method is time-consuming, laborious and inefficient, and it is difficult to provide comprehensive, accurate, scientific and objective information for scientific research.

Embodiment

[0026] Example: such as figure 1 As shown, 1 is the pathological slice to be tested, 2 is the objective lens, 3 is the mirror, 4 is the first imaging lens, 5 is the second imaging lens, and 6 is the CCD camera, wherein the pathological slice 1 to be tested, the objective lens 2, the mirror 3 are located on the same central line in turn, and the direction of light reflected by the mirror is set in sequence with the first imaging lens 4, the second imaging lens 5 and the CCD camera 6, and the working wavelength of the optical system is 587.56nm or 486.13nm or 656.27nm.

[0027] The optical system of a fully automatic digital slice scanner comprises an objective lens 2 on the same optical axis, a fixed first imaging lens 4 and a second imaging lens 5 that can be moved out of the optical axis. When the second imaging lens 5 moves out of the optical axis, The entire optical system is a double optical system; when the second imaging lens 5 moves into the optical axis, the entire opt...

Abstract

The invention discloses an optical system of a fully automatic digital slice scanner, which includes an objective lens and an imaging lens on the same optical axis, and is characterized in that the imaging lens is composed of a fixed first imaging lens and a second imaging lens that can be moved out of the optical axis. When the second imaging lens moves out of the optical axis, the entire optical system is a double optical system; when the second imaging lens moves into the optical axis, the entire optical system is a double optical system, the advantage is that it moves out or in through the second imaging lens The optical axis can conveniently realize the switching between the primary optical system and the secondary optical system.

Description

technical field [0001] The invention relates to a fully automatic digital slice scanner, in particular to an optical system of a fully automatic digital slice scanner. Background technique [0002] Traditional detection, research, and diagnosis based on pathological slices are all done by placing pathological slices on the microscope stage, observing and taking pictures through manual operation. The traditional microscope observation method is time-consuming, laborious and inefficient, and it is difficult to provide comprehensive, accurate, scientific and objective information for scientific research. Information. So in recent years, with the rapid development of computer technology, the digital acquisition and application of pathological images has become a trend. The fully automatic digital slide scanner breaks through the traditional method and can automatically focus on pathological slides. Scanning multiple pathological slices at one time not only has high work effici...
