Details

Designed to satisfy the exacting parameters of infrared focal plane array detectors, thermal imaging and forward looking infrared (FLIR) systems testing in static and moving scene applications, LumaSense’s M345X Series blackbody calibration sources combine fast slew rates, high emissivity, and unchallenged stability and uniformity. As part of an extensive range of general purpose and primary standards for testing and calibrating a wide variety of IR devices, the M345X Series embodies the accumulated expertise of almost 30 years of specialization in this discipline.

The M345X Series Blackbody Sources are cooled and heated by precision thermoelectric modules (Peltier method) and are available in absolute or differential configurations. The two piece system is comprised of 19 inch rack mount controller and a separate emitter source enclosure.

The sources are available in emitter sizes ranging from 4x4 inch (101x101 mm) up to 12x12 inch (305 x 305 mm) and in standard temperature range of 0.00 °C to 170.00 °C (32 to 338 °F) or 0.00 °C to 150.00 °C (32 to 302 °F) for M345X12).

Typical Calibration Applications

  • Infrared Temperature Sensors
  • Infrared Thermal Imaging Systems
  • Spectrographic Analyzers
  • Radiometers
  • Flux Meters

*Ambient temperature must be ≤20 °C to be able to reach 0 °C emitter radiance temperature.
Inlet ducts may be connected to a cool source of air at the top of the blackbody if necessary.
When operating at ambient temperature of 20C and need to make the setpoint 0 °C, the setpoint must be “walked” down to 0 °C.

  1. Set the set point to 10 °C and wait 2 minutes after it is somewhat stable.
  2. Lower the set point to 5 °C, 3 °C, 2 °C, 1 °C, and then 0 °C with about a 2 to 4 minute wait between set points. This permits the heat sink to remain cool.
  3. To minimize hot exhaust air from looping back to the cool air inlets which will hinder its low temperature capability, it is recommended to add two, 2 foot long hoses connected to either the inlets or outlets.
