In in objective table 3, therefore the thickness of optical element turntable 6 can be reduced, and it is compared with the past can constriction optical element turn
The connection space of disk 6 and objective table 3 can reduce the height of objective table 3 while ensuring the amount of keeping out of the way of objective table 3.As a result,
When observing many inspection samples, the amount of movement of the hand of observer can be reduced, can be lessened fatigue.Also, due to optics
Component carousel 6 is directly linked to objective table 3, therefore the Tilt factor of optical element turntable 6 is reduced, and can improve illumination performance.
Further, since the upper surface side in lower objective table 3b is arranged in front lens 7a, therefore front lens 7a is configured near sample S,
Excellent illumination performance can be obtained.In addition, not detachable by the way that optical element turntable 6 is fixed on objective table 3, to
The connection space of objective table 3 constriction in the up-down direction, can further be thinned optics compared with the case where being set as to assemble and disassemble
The thickness of component carousel 6.
In addition, in the above-described embodiment, using optical element 63 of low range, by using shape
Sliding part 36 is set to be moved in the longitudinal direction at the knob 43 of the front-surface side in sliding part 36, to relative to optical axis L
Front lens 7a is plugged, but can also use operation instrument that front lens 7a is made to be moved.Fig. 5 A are embodiments of the present invention
The stereogram of the objective table 3 of variation 1.Fig. 5 B are the partial enlarged views of Fig. 5 A.In figure 5B to eliminate upper objective table 3a's
State is indicated.
It is equipped with the opening 3c being inserted into for operation instrument 50 in the front-surface side of the upper objective table 3a of variation 1.Operation instrument
50 have the holding section 50a of letter U shape in its tip side.It is equipped with ladder screw around knob 43 in guide portion 36
47, by making the holding section 50a of operation instrument 50 engage with ladder screw 47 and being moved forwards, backwards, to relative to optical axis
L plugs front lens 7a.From operation knob 43 is highly difficult on opening portion 16, such as glass is being slided using two pieces or more
It, can be from opening 3c insertion operations tool 50 and relative to optical axis L plug front lens 7a in the case that glass is as sample S.
It is various so as to utilize also, in the above-described embodiment, by configuring multiple optical elements of turntable 65
The observation method of various kinds is observed, but in the case where only carrying out bright field observation, and the rotation of turntable 65 is limited by setting
Locking mechanism, can also limit the rotation of turntable 65.Fig. 6 A are that the optical element of the variation 2 of embodiments of the present invention turns
One pattern of the upward view of disk.Fig. 6 B are the partial sectional views of the optical element turntable of the variation 2 of the embodiment of invention.
In variation 2, it is formed with for the chimeric embedded hole 69 of locking knob 70 in the bottom surface sections of turntable 65.In addition,
Lower objective table 3b is formed with the threaded hole 3d for the threaded portion engagement for locking knob 70.In variation 2, by by embedding
It closes hole 69 and is installed on threaded hole 3d by knob 70 is locked, so as to prevent the optical element 64 of bright field observation from optical axis L
On moved.In addition, in this variation 2, the locking mechanism of bright field observation is illustrated, but can also be with observer's
Demand is set as the locking mechanism of optical element used in other observation methods with being consistent.In addition, as long as locking mechanism can
The rotation of limitation turntable 65 is just not limited to above-mentioned mode, and locking knob 70 can also be installed from the side of turntable 65.
In addition, in above-mentioned embodiment and variation, phase difference use is built-in in turntable 65, dark field is used, is low
Multiplying power with and bright field optical element, but it's not limited to that for optical element.In addition, the optical element of phase difference
It feels relieved, the opening and closing of the opening aperture of bright field is also not limited to above-mentioned mode.In addition, in the present embodiment, including energy
The collector lens of enough the front lens 7a plugged in optical axis L and the rear lens 7b being fixed in lower objective table 3b, but do not limit
In this, can also include can be relative to 1 plugged in optical axis L by carrying out movement on the direction orthogonal with optical axis L
