Introduce
Achromatic objective lens is a common objective lens, which is
composed of several groups of positive and negative glued lenses
with different curved radius. It can only correct the axial color
difference of red and blue light in the spectral line. At the same
time, the spherical aberration of the point on the axis and the
smart aberration of the point near the axis are corrected. This
objective can not eliminate the secondary spectrum. It only
corrects the spherical aberration and chromatic aberration of the
yellow and green wave areas, but does not eliminate the residual
chromatic aberration and the spherical aberration and chromatic
aberration of other wave areas, and the bending of the image field
is still large, that is, only the clear image in the middle range
of the field of view can be obtained. When in use, yellow green
light should be used as the lighting source, or yellow green filter
should be inserted in the optical path. This kind of objective lens
is simple in structure, economical and practical. It is often used
with Fugen eyepiece and correction eyepiece. It is widely used in
medium and low power microscopes. In black-and-white photography,
green color filter can be used to reduce the residual axial color
difference and obtain photos with good contrast.
