Abstract

A microscope equipped with an imaging device used for the positioning of a sample, the microscope capable of removing distortion and blind spots from an image generated by the imaging device and reducing cost by using a commercially available imaging device. A sample holder for holding a sample; a measurement light source for irradiating the sample held by the sample holder with irradiation light; a focusing optical element for focusing measurement light derived from the irradiation light transmitted through or reflected from the sample; a detection unit for detecting the measurement light focused by the focusing optical element; an image capture device for capturing the image of the sample; and an objective optical system switching unit arranged to switch either the focusing optical element or the image capture device with the other to a position facing the sample.

Claims

1-3. -3. (canceled)

4. A microscope comprising:

a) a sample holder holding a sample;

b) a measurement light source irradiating the sample held by the sample holder with irradiation light,

c) a Cassegrain mirror focusing measurement light derived from the irradiation light transmitted through the sample or reflected from the sample;

d) a detection unit detecting the measurement light focused by the Cassegrain mirror,

e) a magnified visible light image capture device capturing an image of the sample through the Cassegrain mirror,

f) an image capture device capturing an image of the sample in a wider imaging area than the magnified visible light image capture device; and

g) an objective optical system switching unit arranged to switch one of the Cassegrain mirror and the image capture device to the other at a position facing the sample.

5. The microscope according to claim 4, further comprising:

an image capture light source irradiating the sample with light having a wavelength detectable by the image capture device.

6. The microscope according to claim 4, wherein the objective optical system switching unit is a revolver switching the Cassegrain mirror and the image capture device by rotation.

7. The microscope according to claim 5, wherein the objective optical system switching unit is a revolver switching the Cassegrain mirror and the image capture device by rotation.
