6. www.magworldwide.com 1) Setup the Camera When selecting a camera for Live Cell Imaging be sure to check for… 1.Sensitivity: Quantum Efficiency at the Spectral Range (Emissions) you will be using. QE: Photon to Electron Conversion Spectral Range e-e- CCD

7. www.magworldwide.com 1) Setup the Camera cont… 2.Linearity: Converting CAPTURED photons into MEASURED gray level. 3.Dynamic range: The number of gray levels in an image or the potential number capable of being recorded by a camera.

8. www.magworldwide.com 1) Setup the Camera cont… 4.Low Noise: System noise refers to electrons in the CCD signal that have their origins in sources other than the object photons. Signal-to-Noise Ratio Object Signal Noise of Surrounding Background =

9. www.magworldwide.com 1) Setup the Camera cont… 5.External triggering: Important for synchronizing your camera with an external device. 6.Full support by the host software: Before purchasing a camera be sure your software package will support it.

11. www.magworldwide.com 2) Set up the Optics & Hardware Important to Note: Hardware controlled via the software means rapid transition between settings. i.e., Motorized filter wheels controlled via InVivo will lower exposure time and save your specimen from harmful light. Keep filter wheel positions close.
