ST60 High Temp: 300°C & 225°C Options

Features

A specially constructed MEMS based thermopile that will withstand operating temperatures of 300°C with Silicon window and 225°C with coated windows*.  The reduced height (.090” tall cover) helps minimize the thermal path and gradient potential of the package.

Options

  • Package hole size options precisely define active area for applications with FOV and/or spot size requirements.
  • See Thermopile Configuration Table for more options.
  • ST60R version offers a low-cost (20% tolerance) poly-silicon resistor to be used as a PTC thermistor.
  • 225°C operation with performance enhancing energy absorber on active area (limited exposure up to 300°C). Extended 300°C operation without performance enhancing absorber. See specs. below.
  • Package hole size options can customize the active are/FoV per specific application(s), data below is based on .047” dia. opening in cap.
  • Internal compensating die option available for additional gradient compensation.
  • Option with Si+DLC window stable to 300°C. *Common physical/spectral properties of window coatings limit their operational temp to ~225°C.
