Peltier Cooled CCD cameras


1: What are the Binning options ?

Downsampling or Binning variations are: 1x1, 2x2, 4x4, 8x8, 16 x 16
Oversampling is also supported.

2: Is the ROI implemented ?

The Region of Interest is not implemented since it does not provide any improvement in readout speed.

3: How is the camera enclosure sealed ?

Sensor’s chamber is hermetic and filled with xenon, but there are no getters or desiccants.

4: Are there different lens mount versions available ?

The MJ042 and MJ081 camera models can be supplied with two mount types: C mount (CS) being the default and M42 mount as optional.
The MJ160 and MJ290 have a special M58 thread with various mount adapters.

5: How many ADCs are present and what frequency and bits are available ?

There are 4 Taps (with 1, 2, 4 options of readout) that offer 52 MHz frequency (including Pixel clock 13MHz, 26Mhz) with 16 bit.

6: What does "Hard AR coated filters" mean ?

It means two things: Hard coating resists mechanical damages and scratches, while AR stands for antireflective coating which improves transmission from ~85% to ~95% in the respective range of wavelengths.

7: How does cooling benefit the camera and sensor performance ?

The dark noise (also referenced as readout noise), which depends on the sensor and electronics noise factors are not relevant in regards to the exposure time.
This is not the same as the dark current, which depends on the sensor leakages (a function of temperature) and exposure time (multiplier).
So, the major benefit of the cooled camera is the lower dark current.
The impact of lower temperature on dark noise (readout noise) is marginal. The improvements in dark current come from CMS (correlated multiple sampling), which in turn makes sense only when the dark current is low enough (below the dark noise).

8: What are the minimum and maximum exposure times that can be set ?

Minimum is 20 us
Maximum is 2147483647us = 2147s = 35m

9: What is the setting range of Sensor Temp and value of the setting step?

Temperature goes down to -10C with steps of 0.5C

10: Is there a Hardware or software trigger possibility ?

Both. Hardware has 1 IN and 1 OUT.
Trigger delays are in nanoseconds range.
The exact values depend on various factors, such as voltage used.
The required voltage levels for the circuitry are High = 2.8V-3.5V and Low = 0V-0.8V
The IO connector is a special one, which will require a specific mating cable with pig-tail end - however, it is not designed yet.
The output can be used to trigger a lighting source, but additional power will need to be provided.
