          Live-Cell Imaging: Enabling 4D Fluorescence Confocal Microscopy

          The Opterra II swept-field confocal microscope utilizes proprietary one-dimensional pinhole array technology to combine the resolution of traditional confocal systems with the speed typically associated with wide-field imaging. 


          With its short acquisition times and cell-protecting minimization of photobleaching and phototoxicity, Opterra II is ideal for advanced live-cell imaging.

          Benefits That Spinning Disk Confocal Simply Cannot Match

          Keep highly sensitive specimens alive, and maintain their cellular function very close to natural biological conditions. Opterra II is ideal for studies ranging from protein localization and trafficking to nuclear, microtubule, and vesicle dynamics.

          Flexibility in Speed, Resolution, and Fluorescence Intensity

          Optimize experimental conditions across an array of life science applications. Opterra II utilizes a unique scanner design that contains both pinholes and slits, which enables flexible adjustment between speed, resolution, and intensity.

          Field Uniformity for Quantitative Analysis of Acquired Images in All Dimensions

          Perform quantiative measurements of fluorescent intensities across and between images. Opterra II's guaranteed field uniformity works with multiple dichroics and provides unmatched quantitative performance right out of the box.

          Low Phototoxicity/Bleaching for Time-Lapsed Volumetric Studies

          Control the dose of excitation light by minimizing exposure time and delivering light to specific locations only when needed. Opterra II enables research on highly sensitive samples, keeping specimens alive and maintaining cellular functions close to biological conditions.

          Ultrafast Imaging at the Speed of Life

          Capture rapid physiological processes in real-time without missing fast transient events. The enhanced swept-field confocal scanning technology of the standard Opterra II allows for high-speed imaging at hundreds of frames per second. With an appropriate camera, over a thousand frames per second can be achieved
