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.

These 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 make your 4x objective give you 40x magnification, 10x gets you 100x, 20x to 200x, 40x to 400x, 60x to 600x, and (with oil immersion) 100x will net you 1000x effective magnification!

You can upgrade just one or more objective lenses as you like at a time, or get the entire set and replace all four of your microscope's objectives. Mix and match, depending on your needs.
