If you purchased the original Microcosmos Microscope, your microscope came with achromatic objectives. Our standard base achromatic objectives are great for microscopy, but due to the nature of the lenses, they display a curved image which results in the edges of the field of view being slightly distorted and out of focus. The plan objectives produce a flat image across the field of view, resulting in an overall sharper image.


This set of plan achromatic microscope objectives fit The Microcosmos Microscope as well as other DIN-standard compound microscopes. With the 10x/18mm widefield eyepieces on the Microcosmos Microscope, these objectives will give you 40x, 100x, 400x, and (with oil immersion) 1000x magnification.

Achromatic Vs. Plan Achromatic Objectives

Achromatic - These objectives work great for people who want to get into amateur microscopy. The image will look great and will be clearly focused in the middle, but because these lenses produce a slightly curved image, the edges can sometimes look slightly out of focus. If you’re just getting into microscopy and aren’t planning on taking a lot of pictures and videos of your samples, these objectives will work great for you.

Plan Achromatic - These objectives produce a flatter image across the entire field of view. This is ideal if you're interested in capturing high quality pictures and videos of the things under your microscope since the center of the image and the edges of the image will all be in focus.

If you decide to upgrade to plan achromatic objectives in the future, we offer a full upgrade set right here.
