Flat field semi complex achromatic lens , Achromatic Objective Lens
SPECIFICATION:
Why does the longer the objective lens, the larger the magnification, the darker the view?
The longer the objective lens of ordinary optical microscope, the larger the magnification, so the distance between the lens and the glass specimen is smaller. Less scattered light is reflected from above, so the field of vision is dimmed, and if the microscope has its own light source, it will not appear.
According to popular one, the larger the magnification, the closer the objective lens is to the loading plate, the less light entering the microscope, and the darker the field of vision.
First, the larger the multiple, the closer the mirror is to the object. Knowing that, when the light is fixed, the smaller the area, the darker of course it is. Conversely, the brighter it is.
If you think about it, when you're using a microscope, and you turn down the magnification and then you turn up the magnification, and you worry that the lens is going to crush the glass, that the lens is going to be longer when you turn up the magnification. The visual field will darken because there is less light coming in.
