<\/p>\n

The Isotech<\/a> Oberon R is a high\u2011temperature blackbody source designed for the realization and maintenance of ITS\u201190 blackbody fixed points. Covering a range from 450 \u00b0C to 1100 \u00b0C and offering an emissivity of >0.995, the Oberon R provides an exceptionally stable and uniform radiation field for calibrating infrared thermometers, thermal imagers and radiometric sensors.<\/p>\n

Sodium heatpipe for exceptional isothermy<\/h3>\n

At the core of the Oberon R is a sodium heatpipe, engineered to deliver extremely low thermal gradients along the furnace core. Once the heatpipe reaches conduction temperature, the inner wall becomes highly uniform, creating ideal conditions for blackbody radiation. The design prevents thermal expansion stresses between the inner and outer walls, and the working fluid is permanently sealed within a plasma\u2011arc welded enclosure for long\u2011term reliability.<\/p>\n

Designed for high\u2011temperature fixed points<\/h3>\n

The Oberon R is ideal for realizing:<\/p>\n

    \n
  • > Aluminium fixed point<\/li>\n
  • > Silver fixed point<\/li>\n
  • > Copper fixed point<\/li>\n<\/ul>\n

    These primary blackbody fixed\u2011point cells are available as options and, combined with the Oberon R, form a highly accurate reference for advanced IR calibration.<\/p>\n

    Blackbody operation from 450 \u00b0C to 1100 \u00b0C<\/h3>\n

    Beyond fixed\u2011point realization, the Oberon R functions as a variable blackbody source across its full temperature range. The 50 mm diameter, 300 mm deep cavity provides a long, uniform radiating column suitable for demanding optical setups.<\/p>\n

    Stable performance and precise control<\/h3>\n

    The Oberon R delivers:<\/p>\n

      \n
    • > Stability: \u00b10.05 \u00b0C<\/li>\n
    • > Emissivity: >0.995<\/li>\n
    • > Display resolution:<\/li>\n<\/ul>\n
        \n
      • > 0.1 \u00b0C up to 999.9 \u00b0C<\/li>\n
      • > 1 \u00b0C from 1000 to 1090 \u00b0C<\/li>\n<\/ul>\n

        The furnace reaches operating temperature in approximately 4 hours, consistent with the thermal mass required for a stable radiation field.<\/p>\n

        Robust construction and modern interfaces<\/h3>\n

        The Oberon R includes:<\/p>\n

          \n
        • > a clear digital display<\/li>\n
        • > PC interface for monitoring and data export<\/li>\n
        • > a powerful 3 kW heater<\/li>\n
        • > a durable 30.5 kg enclosure<\/li>\n<\/ul>\n

          It operates from 110 V, with optional transformers for 230 V or isolation.<\/p>\n

          Options and accessories<\/h3>\n

          Available accessories include:<\/p>\n

            \n
          • > Aluminium Primary Blackbody Fixed Point Cell<\/li>\n
          • > Silver Primary Blackbody Fixed Point Cell<\/li>\n
          • > Copper Primary Blackbody Fixed Point Cell<\/li>\n
          • > Gas Flow System<\/li>\n
          • > 230 V \/ 110 V transformer<\/li>\n
          • > 110 V \/ 110 V isolating transformer<\/li>\n<\/ul>\n

            The Isotech Oberon R is a highly stable, accurate and robust high\u2011temperature blackbody source. With its sodium heatpipe core, high emissivity and precise control, it is an essential instrument for laboratories requiring traceable infrared calibration and ITS\u201190 fixed\u2011point realization at elevated temperatures<\/p>\n
