  • Zeiss AxioObserver with 780-Quasar (34-channel spectral, high-sensitivity gallium-arsenide phosphide detectors, GaAsP) confocal module & fluorescence correlation spectroscopy (FCS)
  • Environmental chamber for 37°C, CO2, & humidity (35mm dishes or chamber slides); Heater box for body of microscope.
  • Definite Focus nosepiece (fast auto-focus to compensate for focus drift during sample heating)
  • NA 0.55 condenser (dry only) with DIC for 20X, 40X, 63X and 100X lenses
  • Objectives:
    • 10X/0.45 PlanApo (dry, no DIC)
    • 20X/0.80 PlanApo (dry, no DIC)
    • 40X/1.30 PlanNeofluar oil, with DIC
    • 40X/1.20 C-Apo water, with DIC, upon request
    • 63X/1.4 PlanApo oil, with DIC
    • 100X PlanApo oil, with DIC, upon request
  • 7 laser lines available:
    • 405 (diode laser),
    • 458, 477, 488, 514 (argon laser)
    • 561 (solid-state)
    • 639 (diode laser)
  • HXP 100W metal-halide illuminator for wide-field fluorescence
  • Fluorescence filter sets (wide-field; non-confocal):
    • #49 for DAPI, #38 for GFP, #43 For Cy3
  • Latest Zen software to control microscope and confocal
  • Zen software on a separate workstation for image analysis.
  • Download Zen LE software available for desktop computers in your lab
    • Analysis with Volocity, Imaris or ImageJ on our analysis workstations
    • Use LOCI BioFormats to import images into ImageJ

Advantages (over other confocals)

  • Like our LSM800 and LSM880Airyscan, significantly less phototoxicity and photobleaching because high-sensitivity GaAsP detectors allow 10-20x less laser power for the same image quality.


  • Single confocal images or image stacks for 3D viewing
  • FRAP with user-defined photobleach marks
  • Photoactivation at 405 nm of caged dyes and other molecules
  • Colocalization of different fluorescent signals
  • Speed and versatility
  • Quasar “fingerprint” system separates very closely spaced fluorochromes. Example: DPPIV-GFP (Golgi, green) and Albumin-Alexa 488 (ER-Golgi, red)
