Clear Observation Images with UIS2 Objective Lens

UIS2 objective lenses are selectable from a wide range line-up of various magnification assortments and special applications according to the requirements. Also available is the high performance that has achieved high quality images with wave front aberration control and the fidelity of color neutral to a specimen in visual observation up to digital imaging.

Brightfield Darkfield DIC Fluorescence



This is a Plan Apochromat objective lens series for brightfield observation with chromatic aberration corrected at the highest level. This series guarantees optical performance (wavefront aberration correction) at a Strehl ratio of 95% or more and is also compatible with the AF unit (Olympus U-AFA2M).



This is a series of universal semiapochromatic objective lenses featuring high-degree corrections for chromatic aberrations. The high performance is available in fluorescence, differential interference contrast, and simple polarized observations not to mention brightfield observation. Use the BD series for the purpose of brightfield/darkfield observation.



This is a series of universal objective lenses featuring high-level performance available especially in polarized and differential interference contrast observations.



This is a series of long working distance plan semiapochromatic objective lenses featuring superb corrections for chromatic aberrations. A long working distance is effectively available for a specimen with steps and for keeping the objective lens from bumping against a specimen under observation. Pupil position is unified for magnifications from 5x through 100x, eliminating the need for switching of the DIC prism otherwise necessary when switching objective lenses. Use the BD series for the purpose of brightfield/darkfield observation.



This is a series of plan apochromatic objective lenses featuring sufficient flatness achieved for the field number up to 22. Use the BD series for the purpose of brightfield/darkfield observation.



The risk of damaging a specimen under observation can be reduced thanks to the long working distance. The high-contrast, color blur-free image allows even the observation of the width of a fine line.



This is a series of objective lenses most suited for the observation of a specimen through glass substrates such as LCD panels. Corrections for aberrations are available according to the thickness of glass substrate thanks to a correction ring adopted.
