Achromatic objective: This is a common objective lens, and the word "ACh" is often written on the shell. This kind of objective lens can only correct the position chromatic aberration (red and blue) and spherical aberration (yellow and green light) of the point on the axis and eliminate the paraxial point coma. The chromatic aberration and spherical aberration of other colored lights cannot be corrected, and the field curve is very large. The earliest achromatic objective lens was made by Zeiss.
When choosing a microscope objective, it is important to keep in mind that objectives are often designed to integrate with a particular manufacturer's microscopes. Before interchanging objectives, be sure to check the design tube lens focal length and the threading type of the objectives. A full list of specifications for each objective can be found in the Specs tab above. Please note that the performance of each objective may vary from the engraved specifications when integrated with components and systems from different manufacturers. See the Magnification and FOV tab for more information.
