Photometrics QV2 - Four-Channel Simultaneous-Imaging System
OVERVIEW
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.
SPECIFICATION
- Number Of Channels: 4
- Sensor Type: CCD
- Wavelength Range: 400 - 750 nm
Applications
• Fluorescence resonance energy transfer (FRET) imaging
• Multicolor single-molecule fluorescence (SMF) imaging
• Multiwavelength total internal reflection fluorescence (TIRF) imaging
• Fluorescence in situ hybridization (FISH) imaging
• Multichannel confocal microscopy when used in conjunction with a spinning-disk confocal
• Two-color polarization/anisotropy studies
• Simultaneous calcium and pH studies with indo-1 and SNARF
• Three-color fluorescence and DIC
• Polarized FRET analysis
• Simultaneous 3D imaging when lenses are used in place of emission filters
KEY FEATURES
• Simultaneous acquisition of up to four images
• Images 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
• 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*
