The Cytation 5 Cell Imaging Multimode Reader is a fully automated plate and slide reader equipped with an inverted widefield configuration.
This unit is capable of imaging from 4-40x with fluorescence and/or brightfield (mono or RGB). It is equipped with three different excitation LEDs and filter sets (there is a fourth slot which is mainly used for hardware-based autofocus, but which can be replaced by a 4th fluorescence channel upon request).
It is also equipped with an atmosphere control unit for regulating CO2 concentration (for live cell imaging), and capable of setting up for hypoxia conditions also. The multimode detection modules include filter- and monochromator-based fluorescence detection, luminescence, and UV-Vis absorbance detection.

Images coming from the Cytation 5 are not calibrated, even though the system has that information available. In the images' metadata you can find the PixelWidth and the ImageWidthMicrons, and by dividing the latter for the first, you get the Pixel Size to calibrate your images. You can find this information below, per objective and Field Of View (FOV):
Objective | FOV | Image Size (pixels) | Image Size (microns) | Pixel Size (microns) |
