• Camera Settings Read/Write
Allows the camera to save its current operating parameters to internal,
non-volatile memory within the Camera Controller. A set number is used as an
identifier for the record. The record of saved operating parameters can then be
applied to the camera. Multiple sets of camera parameters can be stored and
retrieved.
• Gain
Controls the gain applied at the CCD. Values are specified in dB. The value can
be written to or read from the camera. Gain values can range from 0 dB to
34 dB with 1024 levels (10 bits).
• Gamma
Defines a relationship between the incoming light level and the output digital
number. Specifying a gamma value is useful to stretch the dark areas of an
image making the information better suited for viewing with the eye.
• Integration Time
Controls the electronic integration period of the camera. It is identified as
shutter under the IIDC protocol. Values are specified in milliseconds. The
integration time value can be written to or read from the camera.
• Strobe Output (Trigger-Out): The strobe output from the controller provides a
trigger signal that can be used to control strobed illumination sources or other
synchronous events. This function specifies whether the strobe polarity is
negative or positive.
• Trigger (Trigger-In): Uses external signals to control when an image is acquired.
The controller provides a variety of trigger modes. Trigger logic can be specified
as negative or positive. Trigger signals can be sourced from the connector on
the rear panel of the controller or when available, through the frame grabber
cable. Software triggers are also supported.
• Cooling Performance: The Nano-XF is an actively cooled high-resolution 11
Megapixel digital camera. It uses Peltier cooling to significantly reduce both
dark noise and thermal drift. The Nano-XF is designed to cool the CCD to +10°C
at ambient temperature of +20°C.
