For detection, measurement, analysis and control of infrared radiation
The Servo Corporation of America Model 1350 Thermistor IR detector is recommended for use in general infrared systems, pyrometers and other applications requiring broadband optical response from an uncooled detector. These devices have exceptional stability and reliability.
Model 1350 thermistor IR detectors have been developed to satisfy the requirements of a broad range of applications. Active element size, resistance, time constant, and window material specify the detector. Normal tolerances are ± 10% on active element size, ± 20% on resistance (with a ± 5% resistance match between the active and compensator elements), and ± 20% on the time constant. Please consult our applications group with your requirements for different tolerances or specifications.
Actual Element Size: 1.0 mm x 1.0 mm, ± 10%
Nominal Element Resistance: 2.7 megohms, ± 20 %, (BTL #1 material)
Time Constant: 4. 0 milliseconds, ± 20 % (1 /e)
Responsivity: (600 K, 15 Hz): 500 volts/watt, open circuit
N.E.P.(600 K, I5 Hz, I Hz BW): 6 x 10-10 watts/cpsl/2 (less window loss)
Wavelength Response: 2 to 20 microns
Window Material (STD): Germanium
Operating Bias: Approx. 275 volts/element (specified with each unit)
Packaging: TO-8 hermetically sealed
