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

A-2

•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.

(4) This model can be combined with the following observation tubes:

CH3-BI, CH3-TR45, CK40-TBI
