Olympus Water Immersion Objectives offer low to high magnification with extremely high numerical apertures and long working distances. By using water in place of oil, you can effectively overcome common problems with aberrations. Similar to oil immersion objectives, these water immersion objectives are useful for thinly cut tissue sections and living cell imaging, along with other neuroscience applications. Olympus Water Immersion Objectives feature excellent transmission in the IR region, making these lenses are suitable for IR-DIC and fluorescence applications. High numerical apertures also provide superb image quality in combination with most confocal laser microscopes.
