Resolution and ROI frame rate
ROI frame rate is listed after the specification table. The resulting frame rate from
changing sensor height from full image to a single line. Unless otherwise noted,
sensors do not give an increase in readout speed with a reduction in width.

Resolution and ROI measurements
•
Data was generated using
StreamBytesPerSecond
= 124 Mbit/s (full
bandwidth) and an 8-bit pixel format. Frame rates may be lower if using
network hardware incapable of 124 Mbit/s.
•
ROIs are taken as center image for maximum speed advantage, where feature
OffsetY
= (full sensor height – ROI height)/2.
•
BinningVertical
is horizontal row summing on CCD before readout. The frame
rate for an ROI at the same effective height as binning will be slower because
the CCD still needs to read out the “fast readout rows” in ROI mode.
Important notice before reading the specifications tables
All measurements were done without protection glass or 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.
Monochrome Sony CCD/CMOS sensors
The curve in the absolute QE plots shown in this chapter were calculated from a
single measured quantum efficiency for monochrome sensors. The shape of the
curve is from the sensor data sheet but the values have been adjusted based on
this measured value.
Color Sony CCD/CMOS sensors
The curves in the absolute QE plots shown in this chapter were calculated from
three measured quantum efficiency values for color sensors. The shape of the
curves are from the sensor data sheet but the values have been adjusted based on
these measured values.
ON Semiconductor CCD/CMOS sensors & CMOSIS/e2v CMOS sensors
The curve in the absolute QE plots shown in this chapter is from the sensor
manufacturer data sheet.
