The ocular lens is located at the top of the eyepiece tube where you position your eye during observation, while the objective lens is located closer to the sample. The ocular lens generally has a low magnification but works in combination with the objective lens to achieve greater magnification power. It magnifies the magnified image already captured by the objective lens. While the ocular lens focuses purely on magnification, the objective lens performs other functions, such as controlling the overall quality and clarity of the microscope image.

Polyester film supports are highly birefringent, therefore easily identified by interference patterns (i.e. rainbow colours) that are produced when the film is viewed through polarizing filters.

To clean a microscope objective lens, first remove the objective lens and place it on a flat surface with the front lens facing up. Use a blower to remove any particles without touching the lens. Then fold a piece of lens paper into a narrow triangular shape. Moisten the pointed end of the paper with small amount of lens cleaner and place it on the lens. Wipe the lens in a spiral cleaning motion starting from the lens’ center to the edge. Check your work for any remaining residue with an eyepiece or loupe. If needed, repeat this wiping process with a new lens paper until the lens is clean. Important: never wipe a dry lens, and avoid using abrasive or lint cloths and facial or lab tissues. Doing so can scratch the lens surface. Find more tips on objective lens cleaning in our blog post, 6 Tips to Properly Clean Immersion Oil off Your Objectives.
