Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment, and other embodiments may also belong to the scope of the present invention as long as they conform to the gist of the present invention.

[0028] In a preferred embodiment of the present invention, based on the above-mentioned problems existing in the prior art, a light-shielding switching device is now provided, which is applied in a digital pathological slide scanner. The digital pathological slide scanner includes an objective lens 1 and a condenser lens 2 ,Such as figure 1 and figure 2 Shade switching devices shown include:

[0029] A shading plate 3 is arranged between the objective lens 1 and the condenser lens 2;

[0030] A sliding device 4 is connected to the shading plate 3 so that the shading plate 3 can controllably move between a first position between the objective lens ...

Abstract

The invention provides a shading switching device which is applied to a digital pathological section scanner. The digital pathological section scanner comprises an objective lens and a collecting lens, and the shading switching device comprises a shading plate arranged between the objective lens and the collecting lens; and a sliding device which is connected with the light shielding plate, so that the light shielding plate can controllably move between a first position between the objective lens and the condenser lens and a second position between the objective lens and the condenser lens, and when the light shielding plate is located at the first position, shielding is formed between the objective lens and the condenser lens. The invention has the beneficial effects that installation is convenient, the structure is simple, the space utilization rate is high, and automation and intellectualization of light source shielding switching of the collecting lens can be achieved through the light shielding switching device.

Description

technical field [0001] The invention relates to the technical field of optical scanning, in particular to a light-shielding switching device and a digital pathological slice scanner. Background technique [0002] Pathological section is to solidify the diseased tissue or internal organs of the human body by burying, cut into thin slices with a microtome, and then adhere to the glass slide for staining, and present it on the display screen through a microscope and scanner, which is convenient for doctors to observe patients pathological changes, make a pathological diagnosis, and provide assistance for clinical diagnosis and treatment. [0003] Under the prior art, scanning of pathological slices is often disturbed by light generated by the condenser, and observers often use a shield to cover the condenser to block the light source. However, this method is too simple, requires manual operation, and cannot achieve the uniformity of brightfield and fluorescence scanning. Ther...
