For bright-field and fluorescence microscopy imaging applications, Olympus Europa Holding GmbH has released the ultraresolution DP73 and DP73WDR digital cameras. The multipurpose microscope cameras leverage the company's expertise in pixel-shift sensors and high-end consumer digital single-lens reflex camera designs to generate detailed and true-color-reproduction images, achieved using 3-CCD mode and fine-detail process technologies. The DP73WDR uses proprietary WiDER (wide dynamic range) technology to ensure that each image area is always optimally exposed, regardless of any differences in intensity. Both cameras include a high-definition live mode that renders sample browsing comfortable and fluid using the monitor. Active Peltier cooling provides high resolution, accurate and vibrant color reproduction, and effective fluorescence performance. An improved sensor chip and a pixel-shifting mechanism produce maximum resolution of 17.28 megapixels.
