Photometrics QV2™ Datasheet HIGH PERFORMANCE EMCCD & CCD CAMERAS FOR LIFE SCIENCES Four-Channel Simultaneous-Imaging System The Photometrics® QV2™ allows simultaneous acquisition of up to four emission channels in a single exposure. The QV2 uses a series of beamsplitters to split the emission light from a microscope into four separate channels. All four channels are projected onto the CCD at the same time. Simultaneous multichannel imaging is critical for quantitative analysis of emission ratiometric data. Features • Simultaneous acquisition of up to four images • Images can be separated by wavelength, polarization, or amplitude Molecular Probes Alexa Fluor® 350 Molecular Probes SYTOX® Green Molecular Probes Alexa Fluor® 594 Color Overlay • 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 • Bypass mode with bypass filter cube 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.
