Abstract

A microscope illumination intensity measuring device has a light-receiving unit that outputs a signal representing an intensity of received light, a moving mechanism that places the light-receiving unit on an observation optical axis of the microscope as needed, a converter that converts a signal output from the light-receiving unit into light intensity information, a wavelength selection unit that sets a wavelength for light to be measured, and a display unit that displays the light intensity information.

Claims (21)

1. A microscope illumination intensity measuring device, which measures an illumination light intensity of an illumination optical system of a microscope, comprising:

a light-receiving unit that outputs a signal representing an intensity of received light;

a moving mechanism that exchangeably places a specimen to be observed and the light-receiving unit on an observation optical axis of the microscope;

a converter that converts a signal output from the light-receiving unit into light intensity information; and

a display unit that displays the light intensity information.

2. A device according to claim 1 , wherein the moving mechanism comprises a stage which is operable to move the specimen, which is supported on the stage, in a plane perpendicular to the observation optical axis, and the light-receiving unit is disposed on the stage.

3. A device according to claim 2 , wherein the illumination optical system of the microscope includes a motor-driven light control device, and the microscope illumination intensity measuring device further comprises a light control unit that controls the light control device based on the light intensity information obtained by the converter, and a light intensity setting unit that sets a target value for the light intensity.

4. A device according to claim 3 , wherein the microscope comprises a PC-controlled microscope which is controlled by software in a PC, the microscope illumination intensity measuring device includes the PC, and the light intensity setting unit is provided by the software in the PC.

5. A device according to claim 4 , wherein the stage comprises a motor-driven stage which is controlled by the software in the PC.

6. A device according to claim 2 , wherein the stage is moved so that the light-receiving unit is located at a position to which light from the illumination optical system is applied, to measure the illumination light intensity in an observed state.

7. A device according to claim 1 , wherein at least one of the converter and the display unit is provided on a PC.

8. A device according to claim 1 , further comprising a wavelength selection unit that sets a wavelength for light to be measured.

9. A device according to claim 8 , wherein at least one of the converter, wavelength selection unit, and the display unit is provided on a PC.

10. A microscope illumination intensity measuring device, which measures an illumination light intensity of an illumination optical system of a microscope, comprising:

a light-receiving unit that outputs a signal representing an intensity of received light;

a stage that exchangeably places a specimen to be observed and the light-receiving unit at a position to which light from the illumination optical system of the microscope is applied;

a converter that converts a signal output from the light-receiving unit into light intensity information; and

a display unit that displays the light intensity information;

wherein the stage is moved so that the light-receiving unit is located at the position to which the light from the illumination optical system is applied, to measure the illumination light intensity in an observed state.

11. A device according to claim 10 , wherein the light-receiving unit is mounted on the stage, and the stage is movable in a plane perpendicular to an observation optical axis of the microscope.

12. A device according to claim 10 , further comprising a wavelength selection unit that sets a wavelength for light to be measured.
