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.
