Description:
- Achromatic or flat field achromatic objective lenses can correct the positional chromatic aberration (red and blue), spherical aberration (yellow green light), sinusoidal aberration, and eliminate near axis point coma.
- Semi apochromatic or flat field semi apochromatic objectives can correct the spherical aberration and chromatic aberration of red and blue colors.
- The apochromatic and flat field apochromatic objective lens can not only correct the chromatic aberration of multiple colors such as red, green, and blue, but also create images on the same focal plane, achieving the effect of eliminating "residual chromatic aberration" (also known as secondary color spectrum), while correcting the spherical aberration of red and blue colors. It has a larger numerical aperture, resulting in higher resolution, better image quality, and higher effective magnification. The performance of the apochromatic objective lens is very high, and its depth of field is smaller than other types of objectives, so it is more expensive than other types of objectives.
