  • Super-Corrected 60× Objective

HAMBURG, Germany, April 13, 2010 — Olympus Europa Holding GmbH has introduced the PLAPON 60×OSC objective lens with an NA of 1.4, offering high levels of chromatic aberration correction for life sciences imaging applications. This super-corrected objective is designed for fluorescence imaging down to 405 nm. It is suitable for use in cell biology and neuroscience, as well as in any applications requiring lasers for inter- and intracellular imaging of biological specimens.

The lens provides 0.1 to 0.2 µm of chromatic aberration when working with lasers from 405 to 650 nm. Because 405-nm light is used for a variety of scientific imaging applications, this advanced chromatic aberration enables users to perform multicolor imaging with high color fidelity, even at shorter wavelengths. Reliable colocalization and 3-D microstructure studies can be successfully carried out.

It achieves good optical performance and flatness, and even fine lines are clearly defined, reducing the occurrence of shadows at the periphery of the image. Users obtain bright, crisp images from edge to edge. The objective provides good near-infrared fluorescence imaging at up to 850 nm, with a significant reduction in chromatic and other aberration types.

With a working distance of 0.12 mm and a field number of 22, the objective incorporates proprietary technology to enhance point spread function for confocal imaging at low ultraviolet wavelengths. With enhanced flatness and improved brightness at the periphery of the field, the objective is designed for use with an appropriate cover glass and immersion oil. It also can be adapted for use with differential interference contrast.

The lens is constructed using proprietary lead-free ECO glass materials. Signal-to-noise ratios have been enhanced by the specially developed lead-free materials, which reduce the autofluorescence of the components, allowing detection of even the faintest fluorescent signals.
