Objective Lenses
The objective lens is the most complex and the most important component in a microscope. The multi-element design of these lenses works to produce the real image, which is then seen through the ocular lens. With Olympus’ range of microscope objective lenses, we provide outstanding optical performance from visible light to near infrared. The types of microscope objective lenses we have available vary in design depending on your inspection requirements. The MPLFLN-BD has been designed for darkfield observation and the examination of scratches on polished surfaces, whereas the SLMPLN is ideal for electronic assembly inspection. We have a whole selection specifically designed to carry out different inspection tasks across a range of industries. No matter what your requirements, Olympus’ advanced microscope objective lenses have you covered. |  |

Microscope Objective Lenses FAQ
What is the difference between ocular and objective lenses?
The ocular lens is located at the top of the eyepiece tube and is where you position your eye during inspection. The ocular lens has a low magnification, but it works in combination with the objective lens to achieve greater magnification power. It magnifies the magnified image already captured by the objective lens, which is located at the bottom of the microscope. While the ocular lens focuses purely on magnification, the objective lens performs other functions such as controlling resolution and the power of the microscope.
How many objective lenses are on a microscope?
Usually, you will find three or four objective lenses on a microscope, typically consisting of 4x, 10x, 40x, or 100x powers.
What does the objective lens on a microscope do?
Objective lenses are responsible for the primary image formation, determining the quality of the image produced, and controlling the total magnification and overall resolution. They can vary greatly in design and quality.
How do you clean a microscope objective lens?
To clean a microscope objective lens, follow these steps: Remove the objective lens and place it on a flat surface with the front lens facing up. Fold a piece of lens tissue into a narrow triangular shape. Moisten a pointed end of the tissue with cleaner and place it on the lens, then rotate the lens in a corkscrew cleaning motion. Roll up more lens tissue and tear across to create a brush-like end. You should never clean in a circular motion, instead brush across the lens, then use another piece of tissue to remove moisture. Try to avoid using abrasive or lint clothes, and never dry-wipe lenses. This can lead to scratching.
