  • Page 63: Cooling The Array

    Exposure and Signal 7.4 Cooling the Array The detector in the NIRvana-LN is cryogenically-cooled. Although the detector can be operated at temperatures in the range of -175°C to -194°C, pixel gain and offset corrections are optimal when the camera is at its default temperature of -190°C. Generally speaking, the lower the array temperature, the lower the dark current and, therefore, the greater the sensitivity.

  • Page 64: Background Subtraction

    ™ NIRvana -LN System Manual Issue 4 The deepest operating temperature for a system depends on the array size and packaging; and the time required to achieve lock can vary over a considerable range, depending on such factors as the detector type, array type, ambient temperature, etc. Once lock occurs, it is okay to begin focusing.

    Thus, to minimize dark signal effects, the detector temperature should be set for the lowest temperature within the recommended range for the detector. For NIRvana-LN, a default temperature of -190ºC provides the best performance.
