Resources and Facilities

As of October 2013.

The Laboratory for Fluorescence Dynamics (LFD) maintains customized facilities for microscopy, spectroscopy, biochemistry, cell culture, and computing.


Highly customized 2-photon laser scanning microscopes operating in non-descan mode are using FlimBox devices and Cambridge Technology mirror scanners, and are controlled by SimFCS software:

  1. M1: Olympus IX81 microscope with Spectra-Physics MaiTai HP laser for GP, FCS, and FLIM.
  2. M2: Zeiss Axiovert 135TV microscope with Spectra-Physics MaiTai HP laser for FLIM and 3D tracking.
  3. M3: Zeiss Axiovert S100TV microscope with with Spectra-Physics MaiTai HP laser (shared with M2) and Becker & Hickel SPC-830 card for FLIM.
  4. M5: Olympus IX70 microscope with Coherent Chameleon-Ultra II laser for 3D tracking.
  5. DIVER: Olympus microscope with Spectra-Physics MaiTai HP deapsea laser and large area detector for deep tissue imaging.

Commercial one/two-photon confocal laser scanning microscopes with added FlimBox devices and/or 3D tracking capabilities:

  1. ZEISS: Zeiss LSM 510 META-Confocor 3 (one-photon) system with Axiovert 200M microscope.
  2. OLYMPUS: Olympus FluoView FV1000 system with IX81 microscope.
  3. LSM710: Zeiss LSM710 system with AXIO Observer Z1 microscope and spectral detectors.
  4. ALBA: ISS Alba FLIM confocal lifetime imaging system with Nikon Eclipse TE2000-U microscope.

Camera based microscopes:

  1. TIRF: Olympus IX81 microscope with TIRFM illuminator and objectives, Photometrics Cascade EMCCD and Lambert Instruments LI2CAM ICCD cameras, and multiple light sources (405, 458, 488, 515, 544, and 594 nm).
  2. iSPIM: Olympus IX71 microscope with inclined selective plane illumination and Photometrics Evolve camera.

Note that many of the microscopes can be used for multiple types of experiments such as GP, FCS, FLIM, RICS, N&B and 3D tracking.



  1. PERKIN: Perkin-Elmer Lambda 40 spectrophotometer.

Steady-State Fluorescence:

  1. FLUOROMAX: Horiba Jobin-Yvon FluoroMax-4 fluorimeter.
  2. PC2: ISS PC1 photon counting spetrofluorimeter.

Time-Resolved Fluorescence:

Computing Resources

As of October 2014.

The LFD maintains more than 70 computers and printers, a computer lab, dozens of networking services, and hundreds of software packages. The computing facilities are regularly used by more than 25 people. The computer lab, data acquisition computers, servers, and printers are networked via a 1 Gbps Ethernet and are organized in a Windows Active Directory. Detailed documentation is available at the LFD Internal Computing website.

Users of the LFD facilities will be provided with a user account and wireless network connections for personal computers. The LFD does not provide any software or support for private computers.
