CK40M A. OUTLINE OF PRODUCT
A-1
1. Outline
Compact inverted metallurgical microscope, which is flexible to interchange observation tubes
(1) Target market, usage
Industrial inspection market (Sample observation and inspection, and abrasive inspection
at plants and iron works)
(2) External standards acquired
•The product complies with UL and GS. The CE mark was self-declared. FCC is not
applicable.
a) IEC1010-1
b) UL3101-1
c) EN55011 Group 1, class B
d) EN50082-2 (1995)
e) EN61326
(3) Service life
8 years
2. Features
(1) It has only the minimum essential functions required for brightfield and simple polarized
light.
(2) It is easy to operate because it does not have many control parts.
(3) It can be combined with TBI desirable from the ergonomics viewpoint. (Comfortable
standing or seated posture)
(4) It can be used in combination with DP series digital camera.
3. Using conditions
(1) Operating environment
Temperature: 0 - 40°C
Humidity: 30 - 90%
(2) Range of combinations
•When it is combined with CK40-TBI (tilting binocular tube), it is used for field number
18 only. (Flatness is lowered at field number 20.)

CK40M A. OUTLINE OF PRODUCT

•When CK40-MVR (mechanical stage) is mounted on the right side (seen from the
operation knob side) of the plane stage, CK40M-MS (stage mirror) cannot be mounted
on there.
•When it is combined with CK40M-CP (stage plate), the observation range depends on
the objective. In some cases, the CK40M-CP is pushed up by changing to a high
magnification objective. (High magnification)
Combination with MDPlan80X:
The narrow part in the clip hole (shape: tear drop) of the stage plate cannot be
observed. The part around φ15 mm in the clip hole of CK40M-CP is pushed up
by changing to the objective.
Combination with MDPlan50X:
When the clip hole (shape: tear drop) of the stage plate is positioned in the non-
breadthwise direction (when it is not combined with CK40M-MVR), the part
around φ15 mm in the clip hole of CK40M-CP is pushed up in some cases by
changing to the objective.
•When DP10 is combined with NFK2.5X, density may be uneven on one side of the field.
This is a restriction of DP10.
•When it is combined with a TV camera including a photo element, a spot flare may
occur on the TV monitor at a high-reflection mirror when the objective 50X or higher +
NFK2.5X or 3X are used.
(This is caused by surface reflection of the CCD surface and the NFK lens.)
•When it is combined with a TV camera including a 2/3 inch or larger photo element and
NFK1.67X, vigentting will occur at the four corners of the screen.
•When it is combined with CK40M-PO, the polarizer can be rotated more than 90°from
the crossed Nicol (total extinction) position to the index side, but less than 90°in the
opposite direction.
(3) This model can be combined with the following objectives:
MDAch10X
MDAch20X
MDAch50X
MDPlan5X
MDPlan10X
MDPlan20X
MDPlan40X
MDPlan50X
MDPlan80X
This model cannot be combined with the following objectives: LB (long barrel) objectives
other than the above, SB (short barrel) objectives, and UIS objectives.

Double-coated adhesive tape
Longer
Place the reflection protector on
the plate and stick it, aligning the

Plate (AD377800)
(2) Half mirror (LP148000) mounting position
Set the positioning jig (CK40MKC01) on the half
mirror mount. Determine the half mirror position by
pushing the half mirror to the CK40MKC01 and
apply silicone adhesive (OT1873) to the four corners
(bevelled parts) of the half mirror.
The range of adhesive coating should be at least
7 mm per location.
