Olympus Microscope Objective Lenses

Products

MPLAPON

Our MPLAPON plan apochromat objective lens series provides our highest level of chromatic correction and resolution capability, along with a high level of wavefront aberration correction.

MPLAPON-Oil

Our MPLAPON-Oil objective is a plan apochromat and oil immersion lens that provides our highest level of chromatic correction and resolution capability. The numerical aperture of 1.45 offers outstanding image resolution.

MXPLFLN

MXPLFLN objectives add depth to the MPLFLN series for epi-illumination imaging by offering a simultaneously improved numerical aperture and working distance.

MXPLFLN-BD

MXPLFLN-BD objective lenses add depth to the MPLFLN series for epi-illumination imaging by offering simultaneously improved numerical aperture and working distance.

MPLN

Our MPLN plan achromat lens series is dedicated to brightfield observation and provides excellent contrast and optimal flatness throughout the field of view.

MPLN-BD

Our MPLN plan achromat lens series is designed for both brightfield and darkfield observation and provides excellent contrast and optimal flatness throughout the field of view.

MPLFLN

The MPLFLN objective lens has well-balanced performance with a semi-apochromat color correction, a fair working distance, and a high numerical aperture. It is suitable for a wide range of applications.

MPLFLN-BD

The MPLFLN-BD objective lens has semi-apochromat color correction and suits a wide range of industrial inspection applications. It is specially designed for darkfield observation and examining scratches or etchings on polished surfaces.

LMPLFLN

Our LMPLFLN lens is part of our plan semi-apochromat series, providing longer working distances for added sample safety and observation with increased contrast.

LMPLFLN-BD

Our LMPLFLN-BD brightfield/darkfield objective lens is part of our plan semi-apochromat series, providing longer working distances for added sample safety and observation with increased contrast.

SLMPLN

The SLMPLN plan achromat objective lens offers an exceptionally long working distance and the image clarity that you expect from the Olympus UIS2 optical system. It is ideal for electronic assembly inspection and other similar applications.

LCPLFLN-LCD

The LCPLFLN-LCD objective lenses are optimal for observing samples through glass substrates, such as LCD panels. The adoption of optical correction rings enables aberration correction according to glass thickness.

LMPLN-IR/LCPLN-IR

Our LMPLN-IR and LCPLN-IR plan achromat lenses have a long working distance and are specifically designed for optimal transmission in the near-infrared region (700–1300 nm wavelengths).

White Light Interferometry Objective Lens

This objective lens is designed for the Mirau style of white light interferometers and maintains a high level of temperature tolerance. The optimized numerical aperture of 0.8 provides improved light gathering, with a working distance of 0.7 mm.

What’s the difference between ocular and objective lenses?

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.

How many objective lenses are on a microscope?

Many microscopes have several objective lenses that you can rotate to view the specimen at varying magnification powers. Usually, you will find multiple objective lenes on a microscope, consisting of 1.25X to 150X.

What does the objective lens on a microscope do?

Objective lenses are responsible for primary image formation, determining the quality of the image produced and controlling the total magnification and resolution. They can vary greatly in design and quality.

How do you clean a microscope objective lens?

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.
