Fixed frame rate control
The maximum frame rate which can be selected depends on various values, such
as available bandwidth, pixel format, exposure time, and Region of interest (ROI).
Trigger latency
Trigger latency is the camera specific delay between an incoming trigger and, for
example, exposure start. Trigger latency depends on the input type.
Trigger latency with the opto-isolated input
•
The opto-isolated input has a higher trigger latency than the GPIOs as TTL
input. Consider camera aging. Specification values are typical for a new
camera.
•
Trigger on the rising edge to reduce trigger latency. Triggering on the falling
edge doubles trigger latency.

Absolute quantum efficiency (QE) plots
All measurements were done without protection glass / IR cut filter. With
protection glass or filters, quantum efficiency (QE) decreases by approximately
10%. The uncertainty in measurement of the QE values is ±10.25%. This is mainly
due to uncertainties in the measuring apparatus itself (Ulbricht sphere, optometer,
etc.). Manufacturing tolerance of the sensor increases overall uncertainty.
ON Semiconductor CMOS sensors
The curve in the absolute QE plots shown in this chapter is from the sensor
manufacturer data sheet. The information was correct at the time of publishing.
