1. Figures are typical unless otherwise stated.
2. Edge pixels may exhibit a partial response.
3. Cooling is provided by the use of an external mains driven power supply. Minimum
temperatures listed are typical values with ambient temperature of 20°C. Systems are
specified in terms of minimum dark current achievable rather than absolute temperature.
4. Based on horizontal pixel readout rate of 3 MHz and a vertical shift speed of 13 μs.
Achievable spectral rates will vary with selected trigger mode. Due to the nature of the
Open Electrode sensor, the minimum Vertical Shift Speed (VSS) available is 25.7 µs, which will
produce a lower maximum spectral rate compared to other models in the series.
5. Readout noise is for the entire system. It is a combination of CCD readout noise and
A/D noise. Measurement is for Single Pixel readout with the CCD at a temperature of -80°C
and minimum exposure time under dark conditions. Noise values will change with
readout mode.
6. Linearity is measured from a plot of counts vs exposure time under constant photon flux up to
the saturation point of the system.
7. Vertical speeds are software selectable. All sensors are designed to give optimum Charge
Transfer Efficiency (CTE) at 16 μs vertical pixel shift, some decrease in CTE may be observed
at faster shift speeds.
8. The graph shows typical dark current level as a function of temperature. The dark current
measurement is averaged over the CCD area excluding any regions of blemishes.
9. Quantum efficiency of the sensor at 20°C as measured by the sensor manufacturer
10. The chart shows the maximum possible readout rates available when using Multi-track mode,
each track being defined as 20 rows. Crop mode is a specific single-track readout method
