Fluorescence microscopy inspection systems, apparatus and methods with darkfield channel
A fluorescence microscopy inspection system includes light sources able to emit light that causes a specimen to fluoresce and light that does not cause a specimen to fluoresce. The emitted light is directed through one or more filters and objective channels towards a specimen. A ring of lights projects light at the specimen at an oblique angle through a darkfield channel. One of the filters may modify the light to match a predetermined bandgap energy associated with the specimen and another filter may filter wavelengths of light reflected from the specimen and to a camera. The camera may produce an image from the received light and specimen classification and feature analysis may be performed on the image.
1. A slider for a microscope system, comprising:
a body;
a brightfield configuration formed in the body at a first location, the brightfield configuration configured to be selectively positioned along a light path of the microscope system, the brightfield configuration comprising a body defining an aperture in the center of the brightfield configuration, wherein the brightfield configuration allows light to pass through the aperture towards a specimen when selectively positioned along the light path; and
a darkfield configuration formed in the body at a second location spaced separate and apart from the brightfield configuration, the darkfield configuration configured to be selectively positioned along the light path of the microscope system, the darkfield configuration comprising a plurality of lights configured to obliquely illuminate the specimen when selectively positioned along the light path, wherein the center of the darkfield configuration is separate and distinct from the center of the brightfield configuration.
2. The slider for the microscope system of claim 1 , wherein the body is movable between the brightfield configuration and the darkfield configuration via a motor or mechanical mechanism coupled thereto.
3. The slider for the microscope system of claim 1 , wherein the plurality of lights is formed in a ring shaped arrangement.
4. The slider for the microscope system of claim 3 , wherein the ring shaped arrangement is formed about the center of the darkfield configuration.
5. The slider for the microscope system of claim 4 , wherein the darkfield configuration comprises a blocking mechanism configured to prevent light from entering a brightfield channel of the slider.
6. The slider for the microscope system of claim 4 , wherein the darkfield configuration further comprises:
a brightfield channel formed in the center of the darkfield configuration, the brightfield channel allowing light to pass therethrough.
7. The slider for the microscope system of claim 4 wherein the plurality of lights comprises LED lights.
8. The slider for the microscope system of claim 1 , wherein the darkfield configuration is parallel with the brightfield configuration.
9. The slider for the microscope system of claim 1 , wherein the darkfield configuration further comprises:
a brightfield channel formed in the center of the darkfield configuration, the brightfield channel allowing light to pass therethrough.
10. The slider for the microscope system of claim 1 , wherein the brightfield configuration prevents light from passing through a darkfield channel.
11. A microscope system comprising:
a stage comprising a specimen receiving surface configured to support a specimen;
one or more light sources configured to emit light towards a stage of the microscope system;
an objective; and
a slider positioned along a light path between the objective and the one or more light sources, the slider comprising:
a body;
a brightfield configuration formed in the body at a first location, the brightfield configuration configured to be selectively positioned along a light path of the microscope system, the brightfield configuration comprising a body defining an aperture in the center of the brightfield configuration, wherein the brightfield configuration allows light to pass through the aperture towards the stage when selectively positioned along the light path; and
a darkfield configuration formed in the body at a second location, the darkfield configuration configured to be selectively positioned along the light path of the microscope system, the darkfield configuration comprising a plurality of lights configured to obliquely illuminate the specimen when selectively positioned along the light path, wherein the center of the darkfield configuration is separate and distinct from the center of the brightfield configuration,
wherein movement of the slider substantially perpendicular to the light path toggles the slider between the brightfield configuration and the darkfield configuration.
12. The microscope system of claim 11 , wherein the body is movable between the brightfield configuration and the darkfield configuration via a motor or mechanical mechanism coupled thereto.
13. The microscope system of claim 11 , wherein the plurality of lights is formed in a ring shaped arrangement.
14. The microscope system of claim 13 , wherein the ring shaped arrangement is formed about the center of the darkfield configuration.
15. The microscope system of claim 14 , wherein the darkfield configuration comprises a blocking mechanism configured to prevent light from entering a brightfield channel of the slider.
16. The microscope system of claim 14 , wherein the darkfield configuration further comprises:
a brightfield channel formed in the center of the darkfield configuration, the brightfield channel allowing light to pass therethrough.
17. The microscope system of claim 14 , wherein the plurality of lights comprises LED lights.
18. The microscope system of claim 11 , wherein the darkfield configuration is parallel with the brightfield configuration.
19. The microscope system of claim 11 , wherein the darkfield configuration further comprises:
a brightfield channel formed in the center of the darkfield configuration, the brightfield channel allowing light to pass therethrough.
20. The microscope system of claim 11 , wherein the brightfield configuration prevents light from passing through a darkfield channel.
