Introduction:
| The compact MCB-1 is an efficient, easy-to-use inverted type metallurgical microscope. 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 of functions include 35 mm photographing and digital camera photographing |  |
Compact photographing unit
Respective photographing units mounted around lower position of main body are stable 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 are provided as standard. By changing the units, you can easily mount a digital camera (left) or a 35 mm camera (right).

***The Polaroid photographing unit is optional.
Easy-to-operate prefocusing unit
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 high magnification.
Large cross movement mechanical stage with coaxial handle
The ball race type large cross movement mechanical stage is mounted, and its coaxial handle allows easy position adjustment of samples.
Inverted type ideal for inspection of metal samples
The surface of metal sample to be inspected is set downward on the stage, and is immediately ready for observation. Troublesome hand pressing is not required.
Built-in high-intensity lighting unit
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 to permit 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, this Polaroid 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 pattern scale 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 a 10X lens. Magnification of eyepiece: 10X |  |
Object micrometer (for metal) This object micrometer is used to correctly measure the total magnification or the magnification of the objective. It is a kind of standard scale, and 1 mm is equally divided into 100 subsections. |  |
