Description
Technical Field
The utility model relates to a pathological section scanner, concretely relates to double-barrelled fiber optic light source device of changeable light beam and pathological section scanner thereof.
Background
In the pathological section scanner, a unique light splitting optical path design is adopted, so that the objective lens of a microscopic optical path structure is prevented from being switched back and forth. However, this design also brings another problem: the position of the two objective lenses with different magnifications relative to the optical path is fixed, which means that either the light source is moved to match the objective lens, or each objective lens is provided with one set of light source, so that the light source can be used for illumination no matter which objective lens with different magnifications is adopted.
The schematic diagram of each objective equipped with a set of light sources is shown in fig. 1 below: the working principle is roughly as follows: after the system selects the objective lens 3, the system automatically judges the corresponding light source 5, at the moment, the light source 5 is turned on, the other light source 5 is turned off, light rays emitted by the selected light source 5 irradiate the pathological section 4 and enter the objective lens 3, and the condition that only the selected objective lens 3 forms images on the camera 1 through the light splitting mechanism 2 is ensured; after the system selects another objective 3, the system automatically turns off the original light source 5 and then turns on the corresponding light source 5. This ensures that the light sources of the entire optical path system do not interfere with each other.
As shown in fig. 2, the beam moving mechanism 41 with the beam head can move back and forth under the objective lens 3 of two different magnifications by moving the light source to match the objective lens. After the selected objective 3 is used, the beam is moved under the corresponding objective to provide a microscope light source 5.
Both of the above approaches present problems: 1) with the mechanism of fig. 1, two light sources are required to be adopted and respectively controlled independently, so that the cost is increased and a larger instrument installation space is required; 2) with the mechanism of fig. 2, one light source is used, which can save costs, but the beam head moves back and forth with the risk of fiber wear.
