Multi-photon optimized objectives include:

  • 5xÌýNA0.10; MPLN5X-1-7 air, WD 20 (mm)
  • 10xÌýNA0.60; XLUMPLFL10XW-SP water immersion, WD 3.3 (mm);Ìýaka 'The Super 10' (this is a special order lens)
  • 20x NA0.45; IR LCPlan N with correction collar, WDÌý8.93 - 8.18Ìý(mm);ÌýAir, Glass or Silicone
  • 25xÌýNA1.05; FV30-AC25W truResolution water immersion, WD 2.0 (mm) with motorized correction collar (Auto CORR)
  • 60xÌýNA1.10;ÌýLUMFLN60XW LWD water immersion, WD 1.5 (mm)
  • Two non-descanned high-sensitivity GaAsP PMTs
  • Two non-descanned increased-sensitivity multi-alkali PMTs

This microscope is housed in an independent, secured room with significant light mitigation and isÌýinside a custom-made dark box. This microscope is excellent for simultaneous multi-color, deep, in situ imaging of excised or live samples, including tissues and whole animals under anesthesia.
