Olympus FV1000 Confocal Microscope

Confocal Mode

  • Olympus BX61 upright with motorized stage
  • Transmitted light, DIC and epifluorescence (DAPI, FITC, TRITC filters)
  • Simultaneous laser stimulation and imaging via SIM (SIMultaneous) Scanner
  • Fast scanning at 2 microseconds/pixel (16 fps at 256×256, bi-directional scanning), highly customizable scan sequences with a time controller
  • High-speed spectroscopy, FRET, FRAP, uncaging
  • Objectives: 10x dry and water, 40x oil and water, 60x oil and water
  • 3 Laser units with filter configuration providing the following:


Excitation wavelengths (nm) Emission Filters
405 425-475
488 500-550
515 525-565
559 575-625
635 650 Long Pass




  • 3- Dedicated PMT for laser lines
  • Diffraction gratings allow tunable wavelength selection for PMT1 and PMT2 and spectral scanning (lambda scan, up to 100 nm/ms, up to 1nm resolution)
  • 1-DIC PMT (transmitted light detector)
  • A high resolution high sensitivity Infra red camera (18 MP still images, full HD at 30 fps video) to allow visual observation of the sample and electrode under IR light

Two-Photon Mode

  • Ti-sapphire pulsed laser with pre-chirping tunable from 690 to 1020 nm
  • PMT for a green channel

Equipment for Physiological Recordings

  • Siskiyou MX7600 motorized 4-axis micromanipulator and a rotary motion controller
  • Warner Instruments PC505B patch amplifier, and pClamp data acquisition and analysis software
  • Perfusion chamber with associated equipment for oxygenating and heating. A two-channel, DC-powered, low-noise peristaltic pump for circulating solution.
  • Light stimulation system includes two computer controlled calibrated LEDs 528 nm or 475 nm with 500 nm and 455 nm interference filters (FWHM 10 nm). A full field light stimulus is directed to the sample via the condenser. The 455 blue LED allows simultaneous 2-photon imaging and light stimulation.
  • Dissection equipment including dissection microscope with IR illuminator and IR converters.
  • The microscope and related equipment are enclosed in a custom built Faraday cage providing light tight, low noise environment for the optical and electrophysiological recordings.
