Nikon Eclipse Ti microscope
Skirball 2nd floor

Ideal for:

  • TIRF (Total Internal Reflectance Fluorescence) microscopy with an EMCCD camera or sCMOS camera images a defined volume less than 200 nm deep at the substrate. This allows for exceedingly high contrast, high spatial resolution, and high speed imaging of few molecules. Preparations require a #1.5 glass coverslip and aqueous media.
  • Widefield fluorescence microscopy including long time lapse with multiple fields of view. Also, high speed movies with extra wide field of view.
  • Ratio FRET (Förster Resonance Energy Transfer). Using separate color LEDs for excitation and independently addressable filters for emission, ratio FRET can be done on both live and fixed material.

This microscope is for widefield fluorescence, TIRF,simple brightfield, and phase contrast. It has automated focus for Z series and precision stage for tiling large areas or repeatably imaging multiple positions. It may be used for live imaging and for fixed samples.

A few of the specifications:

  • Objectives: Plan Fluor 10x/0.3 Ph1, Plan Apo 20x/0.75 DIC, S Plan Fluor ELWD 40x/0.6 Ph2, Plan Fluor 40x/0.75 DIC, Plan Apo λ 60x/1.4 Oil Ph3 and Apo TIRF 100x/1.49 Oil DIC
  • Widefield excitation by LED at 395, 440, 470, 508, 555, and 640 nm. The 555 nm LED emits in a wide spectral range around 555 nm and may be tailored with narrow pass filters.
  • Emission filters in front of Zyla camera: 435/26; 475/20; 515/30; 540/21; 495/40; 632/60; 700/75.
  • Laser excitation (for TIRF) at 405, 488, 561, 640 nm.
  • Emission filters in front of DU897 camera: 450/50; 525/50; 600/50; 700/75; polarizer.
  • Filter blocks (dichroics): "TIRF-quad"; 86006 CFP/YFP/dsRED; 86012v2 Dapi/FITC/TxRed/Cy5; SRIC (reflection); 89021 GFP/mCherry.

The 60X planapochromat lens is the most versatile for most high resolution imaging. With the Zyla camera it oversamples (the equivalent of a 100X lens). Phase contrast makes it ideal for cell culture imaging. It should be used with a #1.5 coverglass

The 100X lens should only be used for TIRF and other specialized imaging where the sample is within a few um of a #1.5 coverglass.
