Nikon/Andor Ti-TuCam microscope

Profile: Twin-camera system that allows for the simultaneous detection of two signals in widefield.
A digital micromirror device (DMD) from Nikon for photoactivation and photoconversion experiments is also available.


The Nikon/Andor TuCam system is a fully automated Nikon Ti2-microscope with an adaptor that holds two cameras on one port, allowing to image two wavelength at the same time. These cameras are the new Andor Neo sCMOS models with 2560 x 2160 (5.5M) pixel sensors, a pixel area of 6.5 x 6.5 μm and a well number of 30,000 electrons. They can be cooled down to -40°C and offer a sustained readout rate of 30 frames per second (100 fps burst rate).

DMD Module

The DMD module enables photoactivation and photoconversion of a user-specified pattern and position(s), whereas the conventional FRAP unit only enables photoactivation of a single, manually-positioned spot. The DMD illumination shape, size, position and number can be freely customized using the NIS-Elements software. This capability allows researchers to optically mark a subset of cells or protein populations within a single cell or multiple cells to track their behavior. The DMD module is also optimally suited for optogenetics experiments in which highly customized ROIs can be used to optically induce functional changes in subsets of cells or protein populations. On the Ti-TuCam the DMD module is used with LED illumination.
