Microscope table: Anti-vibration table, active dampening, Newport ST-series
Laser:

Spectra Physics MaiTai HP

Laser modulation: LaVision BioTec TriMScope I with fixed pre-chirp, optical beam multiplicator and non-resonance mirror scan head
Microscope stand: BX61WIF (motorized upright microscope)
Detection: Single beam mode: filter based detection system; imaging with up to six detectors is possible (three direct PMT detectors (d=25 mm) at the normal PMT port and three GaAsP detectors (Hamamatsu H 7422-40) at the ultrasensitive PMT port with optional exchange of detectors between the ports). One detector port in transmission below the sample stage (usually not occupied). Spectral filtering is performed by manual selection of dichroic mirrors and bandwidth filters in front of each PMT.
Multi-beam mode:

Two highly sensitive Hamamatsu C9100-02 EMCCD cameras with motorized filter wheel (LaVision BioTec FW8-0036) for spectral filtering.

Fluorescent filters available from 380-670 nm in approx. 20 nm and 50 nm bandwidth steps (including corresponding dichroic mirrors).

Microscope stage: Motorized LaVision BioTec intravital X/Y stage.
Incubation system: Life imaging services incubation system CUBE&BOX. Sensor: Pt-100 thin- layer RTD temperature range: +5° C to 50°C Stability: ± 0.1°C at sensor location, Precision: ± 0.3°C at sensor location
Image acquisition computer: Windows 7 Prof. SP1 64Bit system; Intel i7-3770 CPU @3,40/3,41 GHz, 3,19 GB RAM, Nvidia Quadro 410, 30-inch flat screen, LaVision TriMScope control/trigger board, second AD-Board and Hamamatsu C9100 control board.
Image acquisition software: LaVision BioTec Inspector Pro
Others: Classic HBO fluorescent light source (X-Cite120) including light guide, four fluorescent filter cubes, bright field trans-illumination light source (TH4-200) with an aplanatic achromatic 1.4 condenser. Laser safety glasses and IR-viewer.


 
 

 

Olympus FV1000MPE

Microscope table: Anti-vibration table (active dampening) (Newport RS2000-series)

Bandwidth selection by spectral filters and corresponding dichroic mirrors (in a filter cube) in front of each PMT. Internal optical zoom unit.

Microscope stage: Motorized Prior Z-Deck X/Y stage.
Image acquisition computer:

Windows 7 Prof. 64bit system; Intel Xeon CPU E5-1620-0 @ 3,60GHz/3,60GHz, 8 GB RAM with FluoView interface board, 30 inch TFT- monitor.

Others:

Classic HBO fluorescent light source including light guide, two fluorescent filter cubes. CCD camera Olympus XM10 (12 bit monochrome camera, serial #: 51000191) with Cell-P acquisition software. Laser safety glasses and IR-viewer.
