Magnification : 1. If you are vicuins 9 slide using the 4x obsetive lens then the total Magnification of the object will be 40x 2. If you're viewing a slideusing the look objective lens, the total magnifiction will be 1000x Light Brightness: 1 when you have a lower Power lens in place, I would need less light. 2. when you use a higher power lens, I would need to inclease the amount of light I'm using. Light Intensity: 1. you need to adjust the diaphragm So it can help you enhance the contrast and the resolution of the image. Adjusting Focus: 1. The coarse adjustment knsb 2. Coarse adjustment knob 3. Fine adjustment knob 4. Fine adjustment knob you should never use the course focus knob with the 40x or loox lenses because this could break the lens.
