Photometrics DV2™ Datasheet HIGH PERFORMANCE EMCCD & CCD CAMERAS FOR LIFE SCIENCES Dual-Channel Simultaneous-Imaging System The Photometrics® DV2™ utilizes a single-beamsplitter design to split the emission light from a microscope into two independent channels. Each channel is projected onto half of the CCD at the same time. Simultaneous multichannel imaging is essential for FRET and other emission ratiometric applications. • Simultaneous acquisition of two emission channels • Emission can be separated by wavelength, polarization, or amplitude • Easily mounts to most microscopes • Improved adjustment control enables easier image alignment • Redesigned aperture adjustments ensure apertures are parallel • Uses standard 25-mm-diameter emission and polarization filters Ratio (Green/Red) • Bypass mode permits no-hassle, full-field imaging • Exchangeable filter cube allows multiple applications to be run with minimal realignment • Integrated, adjustable CCD mask minimizes ghosting • Works with many Photometrics® and QImaging® cameras* *Please contact your local representative to verify compatibility with specific cameras.
