CCD detector

G3 Mark II series of CCD cameras are manufactured with two kinds of CCD detectors: OnSemi KAF Full Frame (FF) CCD architecture or OnSemi KAI Interline Transfer (IT) architecture. G3-16200 cameras feature KAF Full Frame (FF) CCD architecture, so we describe the characteristics of this type only below:

G3 cameras with OnSemi KAF Full Frame (FF) CCD architecture. Almost the whole Full Frame CCD detector area is exposed to light. This is why these detectors provide very high quantum efficiency. FF CCD detectors, intended for research applications, are not equipped with so-called Anti Blooming Gate (ABG – a gate, which prohibits blooming of the charge to neighboring pixels when image is over-exposed) to ensure linear response to light through the whole dynamic range. FF CCD detectors used for astrophotography are equipped with ABG to eliminate disrupting blooming streaks within field of view.

“Full Frame” CCD schematic diagram:

Full Frame CCD schematic diagram

Cameras with Full Frame, non-ABG detectors are suitable for scientific applications, where linear response is necessary for photometric applications in astronomy, microscopy etc. High quantum efficiency could be used also for narrow-band imaging, where overexposure is a rare exception, and for imaging of small objects without a bright star in the field of view.

Remark:

  •  Also, G3 cameras with IT CCDs are equipped with mechanical shutter, because electronic shutter does not allow dark-frame exposures, necessary for proper image calibration etc.
  • The price for electronic shutter if lower quantum efficiency (sensitivity) of IT detectors compared to FF ones. Also, all IT detectors are equipped with ABG, so they can acquire images of very bright objects without charge blooming to neighboring pixels.

    Camera Electronics

    16-bit A/D converter with correlated double sampling ensures high dynamic range and CCD chip-limited readout noise. Fast USB interface ensures image download time within seconds.

    Maximum length of single USB cable is approx. 5 m. This length can be extended to 10 m or 15 m by using single USB hub or active USB extender cable. Up to 5 hubs or active extenders can be used in one connection.

    Gx Camera Ethernet Adapter device allows connection of up to four Gx cameras of any type through Ethernet interface and TCP/IP network. Because TCP/IP protocol can be routed, the distance between camera and host PC can be virtually unlimited.

    Camera electronics specifications:

    ADC resolution16 bits
    Sampling methodCorrelated double sampling
    Read modesPreview mode
     Low-noise mode
    Horizontal binning1 to 4 pixels
    Vertical binning1 to 4 pixels
    Sub-frame readoutArbitrary sub-frame
    Computer interfaceUSB 2.0 High Speed
     USB 1.1 Full Speed compatible

    Image download time depends on the CCD chip used in particular camera model. Also the read noise depends on the chip as well as on the read mode.

    • Preview read mode provides system read noise approx. 1 or 2 e- above CCD chip read noise.

    • Low Noise read mode is somewhat slower, but ensures system read noise roughly equal to the manufacturer-specified chip read noise.

    Model G3-16200

    G3-16200 electronics specification:

    Gain0.6 e-/ADU (1 × 1 binning)
     1.0 e-/ADU (other binnings)
    System read noise10 e- RMS (Low noise)
     11 e- RMS (Preview)
    Full frame download9.61 s (Low noise)
     6.77 s (Preview)

    Notes:

    1. Binning can be combined independently on both axes.

    2. Stated read noise is measured on particular CCD sensor, evaluated during camera design. Actual read noise of different sensors varies among various manufacturing batches, but also within single manufacturing batch. The camera read noise is determined by the sensor itself and the camera manufacturer cannot affect it.

    Cooling and power supply

    Regulated thermoelectric cooling is capable to cool the CCD chip from 45 to 50 °C below ambient temperature, depending on the camera type. The Peltier hot side is cooled by a fans. The CCD chip temperature is regulated with ±0.1 °C precision. High temperature drop and precision regulation ensure very low dark current for long exposures and allow proper image calibration.

    G3 cameras are available in two variants, differing in the cooling performance:

    • Standard cooling cameras achieve regulated temperature difference up to 45 °C under environment temperature.

    • Enhanced cooling cameras can regulate temperature up to 50 °C under environment temperature. Compared to standard variant, enhanced cooling cameras are somewhat bulkier due to bigger heat sink, slightly heavier and somewhat noisier because of more powerful fans.

     

     

    Comparison of the G3 Mark II standard cooling camera and enhanced cooling version

    The camera head contains two temperature sensors — the first sensor measures directly the temperature of the CCD chip package. The second one measures the temperature inside the camera shell.

    The cooling performance depends on the environmental conditions and also on the power supply. If the power supply voltage drops below 12 V, the maximum temperature drop is lower.

    Chip cooling specifications:

    CCD chip coolingThermoelectric (Peltier modules)
    Standard cooling ΔT48 °C below ambient maximum
     45 °C below ambient typical
    Enhanced cooling ΔT53 °C below ambient maximum
     50 °C below ambient typical
    Regulation precision0.1 °C
    Hot side coolingAir cooling (two fans)
     Optional liquid coolant heat exchanger

    Remarks:

    • Maximum temperature difference between CCD and ambient air may be reached when the cooling runs at 100% power. However, temperature cannot be regulated in such case, camera has no room for keeping the CCD temperature when the ambient temperature rises. Typical temperature drop can be achieved with cooling running at approx. 85% power, which provides enough room for regulation.
    • Camera construction does not allow usage of both air and liquid cooling. Combined cooling (air with the liquid cooling option) is not available, because such cooling does not work effectively enough with air only nor with water only.

    Power supply

    The 12 V DC power supply enables camera operation from arbitrary power source including batteries, wall adapters etc. Universal 100-240 V AC/50-60 Hz, 60 W “brick” adapter is supplied with the camera. Although the camera power consumption does not exceed 40 W, the 60 W power supply ensures noise-free operation.

    Power supply specifications

    Camera power supply12 V DC
    Camera power consumption15 W without cooling
     52 W maximum cooling
    Power plug5.5/2.5 mm, center +
    Adapter input voltage100-240 V AC/50-60 Hz
    Adapter output voltage12 V DC/5 A
    Adapter maximum power60 W

    Warning:

    The power connector on the camera head uses center-plus pin. Although all modern power supplies use this configuration, always make sure the polarity is correct if other than the supplied power source is used.

    Remarks:

    • Power consumption is measured on the input (AC side) of the supplied power adapter. Camera consumes less energy from 12 V power supply than state here.
    • The camera contains its own power supplies inside, so it can be powered by unregulated 12 V DC power source — the input voltage can be anywhere between 10 and 14 V. However, some parameters (like cooling efficiency) can degrade if the supply drops below 12 V.
    • G3 camera measures its input voltage and provides it to the control software. Input voltage is displayed in the Cooling tab of the Imaging Camera control tool in the SIPS program. This feature is important especially if you power the camera from batteries.

    Mechanical Specifications

    Compact and robust camera head measures only 154 × 154 × 65 mm (approx. 6 × 6 × 2.6 inches) for the model with standard cooling. Enhanced cooling increases camera depth by 11 mm.

    The head is CNC-machined from high-quality aluminum and black anodized. The head itself contains USB-B (device) connector and 12 V DC power plug, no other parts (CPU box, USB interface, etc.), except a “brick” power supply, are necessary. Another connector allows control of optional external filter wheel. Integrated mechanical shutter allows streak-free image readout, as well as automatic dark frame exposures, which are necessary for unattended, robotic setups.

    Mechanical specification

    Remark:

    Back focus distance is measured from the sensor to the base on which adjustable adapters are mounted. Various adapters then provide back focal distance specific for the particular adapter type (e.g. Canon EOS bayonet adapter back focal distance is 44 mm).

    Stated back focal distance already calculates with glass permanently placed in the optical path (e.g. optical window covering the CCD cold chamber).
