Overview:

Santa Barbara Infrared's Infinity Series of Differential Blackbodies (DB Series) are designed to support the most critical IR testing requirements. The Infinity blackbodies offer the best performance available. Fast, stable, uniform, accurate and reliable, these blackbody systems provide performance enhancements and features that set them apart from previously available systems. A key feature is the new iProbe from SBIR. This intelligent temperature sensor is calibrated independently of the blackbody system. To re-calibrate the system you need only exchange the probe with a recently calibrated one. No special equipment is required thus minimizing downtime. Our blackbodies are designed for use as flood sources for non-uniformity correction or sensor calibration, and as differential sources for MRT, MTF, SiTF and other standard IR sensor characterization tests.

Features:

• Intelli-Probe (iProbe)
  The iProbe from SBIR is an intelligent temperature sensor that is calibrated independently of the blackbody system. To re-calibrate the system you need only exchange the probe with a recently calibrated one. No special equipment is required thus minimizing downtime.
  
  
• Accuracy
  
  Ultra-stable, highly responsive iProbes are used to provide very precise control and accurate system performance. The iProbes are calibrated to an accuracy of under 0.010ºC. System uncertainty including calibration and stability is +/- 0.01ºC or +/- 0.1% of set delta T whichever is greater.
  
  
• Uniformity
  The Infinity blackbody incorporates design and construction features that maximize spatial uniformity and minimize convection influences resulting in typical surface uniformity of > 98% of set differential temperature or 0.01ºC, whichever is greater over 90% of the emitting surface area.
  
  
• Emissivity
  
  A surface treatment is used to create a spectrally flat emissivity of greater than .970 for 2µ to 14µ.
  
  
• Milli-Kelvin Temperature Stability
  
  SBIR has developed unique temperature measurement and analog-to-digital conversion circuitry with integrated control logic that results in extremely responsive temperature control. True set point and accurate milli-kelvin control have been achieved allowing for precision testing at contrast levels of 1 milli-kelvin.
  
  
• Multi-Function Controller
  
  The controller features a touch screen display and supports remote computer control over Ethernet or RS-232. The controllers are also available with an optional IEEE 488 GPIB Interface.
  
  The controller will also operate all of the SBIR peripherals: target wheels, visible illuminators, pulsed laser diodes, range slides, source slides and filter wheels.
  
  
  
• Automatic Radiometric Compensation
  
  Attenuation caused by optics, differences in emissivity, ambient temperature change, and waveband of interest result in system output that is not radiometrically correct. When operating the controller in the radiometric mode, compensation for these factors is automatically applied, adjusting the blackbody as required to maintain the proper system output.
  
  
• IRWindows™ Advanced EO Test and Analysis Tool
  
  The Infinity Series is optimized for seamless integration with the SBIR IRWindows™ test system. IRWindows™ is an advanced software tool that automates the setup, execution, data collection and results analysis for industry standard performance testing of infrared, visible and laser sensor systems.
  
  
• Configurations
  
  The Infinity Differential Blackbody system includes a temperature controller (19” rack mount or desktop configuration), blackbody head, interconnect cable, power cable and manual. The blackbody heads are available with emitting surface sizes including 4”, 6”, 8” and 12” square. Standard and optional temperature ranges can be viewed in the Specifications section.

Options:

• IEEE Std. 488 Interface (GPIB)
  The thorough implementation of the ANSI/IEEE Std. 488.1-1987 allows for computer control of all blackbody, calibration, illuminator, and target wheel functions.
  
  
• Radiometric Differential Temperature
  Differential temperature errors due to optical attenuation or emissivity differences can be corrected with this feature.
  
  
• Illuminator
  A visible alignment light moves into and out of the optical path to backlight the target. The illuminator position is controlled from the front panel or via the computer interface options. Light level luminance is preconfigured and adjustable at 10 various intensity set points. This feature is very useful for visible alignment of the system. IR-to-visible boresight tests can be made with uncompromised accuracy because the target is stationary during IR to visible transition.
  
  
• Targets
  Many standard and custom infrared targets are available. These targets can be supplied with either emissive or reflective coatings. See the Target section for details.
  
  
• Target Wheels
  Multiple targets can be rapidly and precisely positioned in front of the blackbody. Target position can be set from the front panel of the controller or via the computer interface. For details on the full line of target wheels see SBIR’s Target Wheel section.
  
  
• Rack Mounting
  The blackbody controller is designed for bench-top or standard 19 inch rack use. Rack mounting ears come standard with the instrument. A rack slide kit is also available.
