-
Figures are typical unless otherwise stated.
-
Quantum efficiency as supplied by the sensor manufacturer.
-
Coolant temperature must be above dew point.
-
Linearity is measured from a plot of Signal vs. Exposure Time over the full dynamic range.
-
Software Exposure Events provide rapid software notification (SDK only) of the start and end of acquisition.
-
The Sona connects to your control PC using a USB 3.0 connection. This may also be referred to as USB 3.1 (Gen 1). Andor provide a USB 3.0 card and cable, and recommend that these are used to ensure optimum performance.
