Q2 for Multiphoton Imaging

Q2 is a laser scanning nanoscope (LSN) that incorporates several measurement modalities for experimental quantitative biology and material sciences applications requiring the single molecule detection sensitivity.


Key Features of Q2 Laser Scanning Nanoscope:

  • Single- and multi-photon excitation on three separate input ports
  • Two channel acquisition
  • One, computer-controlled-aperture, pinhole
  • Fast scanning mirrors
  • Powered by VistaVision, a user-friendly software package for the acquisition of confocal images, FLIM/ FRET, RICS, and FFS (FCS, PCH, scanning FCS, N&B)
  • Excitation Modality
  • Three separate input ports allow for simultaneous alignment of one-photon excitation (laser diodes and supercontinuum laser) or multi-photon measurements (fiber laser, Ti:Sapphire laser).
