Overview of Two-Channel Acquisition Unit

The Two-Detectors Unit (TDU) provides automation in the selection of filters and dichroics in front of the two detectors. The fluorescence light is brought to the unit from the confocal head of the microscope by using a multimode fiber (50 - 100 µm diameter) with FC connector.

At the entrance of the unit the light is split by a dichroic filter. A computer-controlled filterwheel mounting up to five dichroic allows for the fast switching between the dichroic. The light is directed into each channel equipped with a five-position filterwheel; a shutter is positioned in front of each detector protected by an overload circuitry. Communication is through the USB protocol.

The unit is used as a stand-alone in custom-built systems or in the FLIM/FFS Upgrade Kits of Laser Scanning Microscopes.

Compatible with Q2, and PL1.
