Magnifying observation apparatus
First Claim
1. A magnifying observation apparatus comprising:
- a specimen chamber being able to decompress as an internal space;
an electron beam imaging device as a first observation device for obtaining an electron microscope image in the specimen chamber, and wherein said electron beam imaging device has an adjustable electron magnifying power range;
an electron microscope magnifying power adjusting section that adjusts an electron microscope magnifying power of the electron microscope image obtained by the electron beam imaging device;
an optical imaging device as a second observation device for obtaining an optical image in the specimen chamber, and wherein said optical imaging device has an adjustable optical magnifying power range, and said adjustable electron magnifying power range has an overlapping range with said adjustable optical power range;
an optical magnifying power adjusting section that adjusts an optical magnifying power, the optical magnifying power being a magnifying power of the optical image obtained by the optical imaging device, the optical magnifying power being determined on a basis different from that of the electron microscope magnifying power;
a moving device that moves each of the observation devices such that an optical axis direction of one of the observation devices is substantially aligned with an optical axis direction of the other observation device;
a display section that displays the electron microscope image obtained by the electron beam imaging device and the optical image obtained by the optical imaging device while switching between the electron microscope image and the optical image, or simultaneously displays the electron microscope image and the optical image; and
a magnifying power conversion section that recognizes the magnifying power of a first image obtained by the optical imaging device within the overlapping range and converts the magnifying power into a converted magnifying power, on a basis of the electron beam imaging device, which is used by the electron beam imaging device, to obtain a second image having a display size that is substantially identical to that of the first image; and
wherein the electron microscope magnifying power adjusting section adjusts the electron microscope magnifying power to the converted magnifying power from the magnifying power conversion section.

Abstract
Work to obtain an optical and an electron microscope images at an identical display size is facilitated. A magnifying observation apparatus includes: an electron beam imaging device that obtains an electron microscope image in a chamber; an optical imaging device that obtains an optical image in the chamber; a moving device that moves the both devices such that an optical axis direction of one of the both devices is aligned with an optical axis direction of the other device; a display section that displays the electron microscope and the optical images; and a magnifying power conversion section that recognizes a magnifying power of an image obtained by one of the imaging devices and converts the magnifying power, which is used to obtain an image having a display size substantially identical to that of the image, by the other device into a magnifying power on a basis of the other device.
