Nikon microscope 3





Screening, slide/tissue scanning, bright field/DIC imaging, fluorescence imaging, fixed and live cell imaging, multi position imaging, imaging of samples on slides, dishes and multi well plates, time series, Z-series.

The system can handle slides, 35 mm dishes and multi well plates. A holder for 4 slides is available.

With funding from the University Equipment Fund this system has been upgraded with Nikons' high content screening module JOBS and a 20x objective in August 2013. The JOBS software is a module of NIS-Elements which allows us to use this microscope as a screening station, using slides, dishes or multi well plates. Recently a further upgrade of JOBS has been installed which allows for automatic tissue scanning on slides.

The Nikon3 microscope is a fully motorized system build on a Nikon eclipse Ti-E microscope. This microscope a LED light source for the wavelengths 365nm, 490nm, 565nm and 635nm for normal epifluorescence microscopy. For fast live cell imaging a dual filter block for excitation with 490 nm and 565 nm has been installed on this system. The system is has an environmental chamber with CO2 and temperature control as well as the Nikon Perfect Focus System (PFS) to keep the samples in focus during long live time imaging experiments.


For fluorescence image acquisition an Andor iXonEM+ EMCCD DU 885 camera is attached to the microscope. This is a 14 bit camera which can operate in both EM-CCD and CCD mode, has a pixel size of 8 x 8 µm and an image size of 1004 x 1002 pixels. Camera Specs.

A Nikon DS-Fi2 colour camera with DS-U3 controller has been installed on Nikon microscope 3 in autumn 2016. This upgrade allows for faster imaging of immunohistochemistry samples. Nikon 3 is now equipped with 2 cameras and the user has to chose which camera to use (Andor EM-CCD or Nikon DS-Fi2) when opening the NIS-Elements software. This purchase was funded by income generated by the ImageJ workshops organized by AIF.
