Abstract
Abstract A microscope having an optical head and an additional head is disclosed. A slide plate on which the additional head and optical head are arranged in such a manner that they are separated by a predetermined spacing in the Y direction is slidably secured to an arm of the microscope. Under such a construction, an observation by a raster image and an optical observation by a optical image can be performed precisely for the same region of a specimen by moving the additional head and optical head integrally by a distance substantially equal to the spacing by means of the slide plate.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
117 words
A microscope comprising an optical head for observing an optical image of a specimen and at least one additional head for observing a raster image of the specimen on a specimen stage by scanning the specimen in a main-scanning direction and in a sub-scanning direction substantially perpendicular to the main-scanning direction, comprising a supporting means for supporting said additional head and optical head arranged separately from each other by a predetermined distance, said supporting means being slidable in a such manner that a center point of a raster image field is made identical with a center point of an optical image field, wherein said supporting means is slidable in a direction substantially parallel to the sub-scanning direction.
Claim 2
Dependent Claim
117 words
A microscope comprising an optical head for observing an optical image of a specimen and at least one additional head for observing a raster image of the specimen on a specimen stage by scanning the specimen in a main-scanning direction and in a sub-scanning direction substantially perpendicular to the main-scanning direction, comprising a supporting means for supporting said additional head and optical head arranged separately from each other by a predetermined distance, said supporting means being slidable in a such manner that a center point of a raster image field is made identical with a center point of an optical image field, wherein said supporting means is slidable in a direction substantially parallel to the sub-scanning direction.
Claim 3
Dependent Claim

Claim 5
Dependent Claim
40 words
A microscope according to claim 1, wherein the supporting means is movably secured to an arm of the microscope and the movement of the supporting means is limited by a click mechanism arranged between said arm and said supporting means.
Claim 6
Dependent Claim
44 words
A microscope according to claim 1, wherein said additional head is an ultrasonic head, and the scanning operation for obtaining the raster image is effected by vibrating the ultrasonic head in the main-scanning direction and by moving said specimen stage in the sub-scanning direction.
Claim 7
Dependent Claim
41 words
