A light source stage on a microscope holder capable of observing the ultrafine structure of sample surfaces

Abstract

This invention provides a light source module for an optical microscope, comprising a ring-shaped illumination source, a spherical stage, and a reflector assembly. The ring-shaped illumination source includes a ring-shaped base connected to an optical fiber, the inner surface of which has a plurality of perforations; the spherical stage is disposed inside the ring-shaped base; the reflector assembly is disposed on the ring-shaped base and includes a hollow cylinder and a curved reflector. Light provided by the ring-shaped illumination source is projected through the plurality of perforations and the gap between the ring-shaped base and the spherical stage onto the curved reflector, and then reflected onto the sample to obtain a clear and three-dimensional live image.

Claims

1. A light source module for an optical microscope, comprising: an annular illumination source including an annular base connected to an optical fiber, wherein an inner annular surface of the annular base has a plurality of perforations; a spherical stage disposed inside the annular base, the top of the spherical stage being used to support a sample; and a reflector assembly disposed on the annular base, the reflector assembly including a hollow cylinder and a curved reflector, the curved reflector being disposed within the hollow cylinder and covering the spherical stage, wherein... The light provided by the ring-shaped illumination source is projected upwards through the plurality of perforations in the ring-shaped base and the gap between the ring-shaped base and the spherical stage onto the curved reflector, and then reflected onto the sample on the spherical stage.

2. The light source module of the optical microscope as claimed in claim 1, wherein the mirror assembly further includes an adjustment plate screwed to the outer circumferential surface of the hollow cylinder, thereby adjusting the height of the curved mirror.

3. The light source module of the optical microscope as described in claim 2 further includes a connecting base disposed on the annular base and surrounding the spherical stage.

4. The light source module of the optical microscope as described in claim 3, wherein the outer diameter of the adjustment plate is larger than the outer diameter of the outer circumferential surface of the connecting base.

5. The light source module of the optical microscope as described in claim 3, wherein the connecting base is provided with a plurality of positioning members, and the hollow cylinder of the reflector assembly is provided with a plurality of grooves on the outside for receiving the plurality of positioning members therein.

6. The light source module of the optical microscope as described in claim 3, wherein the outer diameter of the hollow cylinder is smaller than the inner diameter of the inner circumferential surface of the connecting seat.

7. The light source module of the optical microscope as described in claim 1, wherein one of the light sources connected to the optical fiber is a light-emitting diode light source or a xenon lamp light source.

8. The light source module of the optical microscope as claimed in claim 1, wherein the curved mirror has a central objective lens inspection hole that is aligned with the sample on the spherical stage.

9. The light source module of the optical microscope as claimed in claim 1, wherein the top of the spherical stage is provided with a support plate for supporting the sample.

10. The light source module of the optical microscope as claimed in claim 1, wherein the spherical stage has a through hole at its center, the through hole having an internal thread and an adjusting shaft screwed into it, the height of the spherical stage being adjusted by rotating the adjusting shaft relative to the spherical stage.
