Using Your Retiga ELECTRO Camera
Imaging Software
The Retiga ELECTRO cameras comes with a full featured camera control application, Ocular imaging software.
For an up-to date list of other compatible third-party imaging software applications, please visit our website at
http://www.qimaging.com.
The Retiga ELECTRO camera’s image capture capabilities are controlled entirely through your imaging software.
Basic functionalities include control over exposure time, gain state, clearing mode, region of interest (ROI), and
pixel binning. Additional information on camera use and CCD operating is available on the web, please visit:

Basic Camera Parameters
Exposure Time
The Retiga ELECTRO camera’s exposure controls allow you to adjust the integration time for each acquisition.
By increasing the exposure time, more light is captured by the sensor and a better signal-to-noise ratio (SNR)
is achieved. The exposure time should be adjusted to a level that achieves the shortest integration time
possible while still maintaining sufficient SNR.
Gain State
Gain (with regards to cameras) is defined as the conversion factor of captured electrons to a digital signal,
often referred to as a grey value or ADU (Analogue to Digital Unit) and has units of electrons per ADU (e/
ADU). Knowing the gain of a camera allows users to directly compare an ADU value as measured from their
software to the physical number of electrons actually captured by the camera’s sensor. Gain plays a critical
role in many of the camera’s parameters including dynamic range and read noise.
The Retiga ELECTRO camera provides two user-selectable gain states that enable optimal camera
performance for different imaging environments. Refer to Certificate of Performance provided for different
gain states values.
