BMS C2, Operation Instruction Manual

MICROSCOPY 

1. Lamp 

illumination 

Turn the brightness control dial forward to achieve the desired 

brightness. 

2. Specimen 

Mounting 

Mounting with the cover glass facing upwards. 

3. Focusing with 10X Objectives 

Choose the objective 4X or 10X. Turn the coarse focusing 

knob to get the objective focused on the slide and then turn 

the fine focus adjustment knob to get the image sharp and 

clear. 

4.Interpupillary Distance Adjustment 

Adjust the interpupillary distance of binocular until the 

right-left field of view can be composed one.   

5. Eyepiece Diopter Adjustment   

Firstly, observe at right tube with right eye, adjust coarse-fine 

focusing knob to image clearly. 

Secondly, observe at left tube with left eye, adjust the diopter 

control 1 to image clearly. 

6. Objective Selection   

Rotate the revolving nosepiece to the desired objective 

magnification, assuring it click-stops into position. 

7. Aperture Diaphragm Adjustment 

(This diaphragm is designed for numerical aperture 

adjustment, not brightness.) 

General, a good image of sufficient contrast can be achieved 

with the aperture diaphragm stopped down to approximately 

70-80% of the objective’s numerical aperture. To observe the
