How to operate a metallographic microscope?

Metallographic microscopes are durable equipment, the optical components are very precise, if operated correctly, then it is as good as other

There is no difference in the equipment. And now the optical microscopic equipment is seely manufactured, the protection measures are very perfect, basically can avoid misoperation. It is important that the operator understands the operation of the corresponding microscope before using it. So today, the small edition of Fulai will introduce the operation of the metallographic microscope.

1. Placement

Because it is an optical instrument and equipment, there are certain requirements for light, and it needs to be in a position with sufficient light, and the place near the window is more suitable. Moreover, optical lenses have requirements for the cleanliness of the surrounding environment, and it is important to keep the environment clean. In addition, the workbench must be smooth, usually the operator on the right side of the metallographic microscope, distance from the workbench side to maintain a position of 4cm-8cm.

Two, clean

The mechanical part of the fuselage should be wiped with a clean soft cloth, and the lens should be wiped with mirror wiping paper. If glue or sticky stains are found, a small amount of xylene can be used to clean it. Be sure to use light hands when cleaning lenses, and you must use professional lens cleaning paper for cleaning.

Three, the lens of the light

Raise the lens barrel to the position of 1cm-2cm away from the stage, and align the low-power lens with the light hole. Adjust the aperture and mirror, use a flat mirror when the light is strong, use a concave mirror when the light is weak, and turn the mirror with both hands. If you are using a microscope with a light source, you need a knob to adjust the brightness of the light.

Four, the focus of the lens

When focusing, first rotate the coarse focusing knob to slowly lower the lens barrel, carefully observe from the side until the objective lens is close to the specimen, then observe from the eyepiece, rotate the coarse focusing knob with the right hand to lift the lens barrel until the specimen image is clear, and then use the fine focusing knob to adjust back to clear. Using binocular eyepieces, the binocular can be shifted relative to each other to adapt to the distance between the operator's eyes. If the observer's binocular vision is different, the visibility adjustment ring can be used to adjust. One thing to note: To understand the critical value of the object distance, the distance between the tube and the specimen should be observed from the side when the tube is lowered; You can't focus directly at high power.

The above is the operation of metallographic microscope introduced by the small edition of Shanghai Fulai Optical Technology Co., LTD. For more product information, you can enter the official website of Shanghai Fulai Optical Technology Co., LTD.
