and operation in the factory

Inverted Type
Metallurgical
Microscope
MCB-1
The compact MCB-1 is an efficient,easy-to-use inverted type metallurgicalmicroscope. The combination of a flatfield objective lens with outstanding
resolution even around the periphery of
the field of view and a high eye-point
eyepiece with a wide field of view
permits prolonged microscopic
observation without fatigue. A wealth offunctions include 35 mm photographingand digital camera photographing.
* Digital camera is optional.

Compact photographing unit

Easy-to-operate prefocusing unitRespective photographing units mounted
around lower position of main body arestable and easy to operate. Two types of units
with a 4X Camera Lens for a 35 mm camera
and a 0.7X TV Lens for a digital camera areprovided as standard. By changing the units,
you can easily mount a digital camera (left)or a 35 mm camera (right).

The stage moves vertically by the coarse
adjustment handle and stops at a fixed
position that has been adjusted as a focusing
point. The objective lens has the same focal
point at respective magnifications, permitting
quick change from low to highmagnification.

Inverted type ideal for
inspection of metal samples
The surface of metal sample to be inspected
is set downward on the stage, and isimmediately ready for observation.
Troublesome hand pressing is not required.

35 mm camera

The ball race type large cross movement
mechanical stage is mounted, and its coaxial

The Polaroid photographing unit isoptional.

The stage, which measures
150 mm x 160 mm, moves
30 mm in the X and Ydirections.

The transformer is built into the base. The
reflected illumination unit is a Koehler
illumination type with an aperture and a field
diaphragms.

A variety of options useful for material inspection
35 mm Camera Attachment
The 4X Camera Lens for a 35 mm camera
comes with Asahi K Mount as standard topermit an Asahi Pentax to be mounted directly.
Select separate mounts to attach other cameras.
Magnification on film surface: Magnification of
objective x 4

3"x4" Polaroid photographing unit
A 10X photographing lens and a shutter are
built into the unit. After the photographing
unit is removed from the microscope, thisPolaroid unit is inserted.
Magnification on film surface:
Magnification of objective x 10

Eyepiece for measurement of austenite grain size
This is used to measure the size of austenite
grains in steel. The grain size patterns
corresponding to grain sizes No.1-No.8 are
drawn within the field of view, and a microscopic
image is seen through the vacant center.

Transmitted illumination unit
Observation with transmitted light is possible by attaching this unit
to the back of the stage bracket of the microscope. This is effective
for observing fine powder and transparent samples. An 8V, 15W
tungsten lamp is adopted.

Eyepiece for nonmetallic inclusion test (JIS G0555)
This eyepiece has a point-counting grid patternscale that conforms to JIS. Two types of scales,for Method 1 and Method 3, are provided. The
scale for Method 3 is used together with a 40X
lens, while the scale for Method 1 is used with a10X lens.
(Magnification of eyepiece: 10X)

0. 40mmObject micrometer (for metal)
This object micrometer is used to correctly measure
the total magnification or the magnification of theobjective. It is a kind of standard scale, and 1 mm isequally divided into 100 subsections.
