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.
