Hamamatsu Photonics New High Sensitivity Single Element Thermopile Sensor for Infrared Detection


10/5/2011 11:02:48 AM

October 05, 2011 -- Hamamatsu Photonics have developed a brand new series of thermopile infrared detectors, to meet the demand for low cost sensors with high S/N for gas analysis applications.

The T11262-01 is a high sensitivity thermopile sensor with a D* of 1.3x108. The sensor is housed within a compact TO-18 package with a high transmittance window in the 3-5┬Ám band. The T11262-01 also benefits from a low element resistance and low temperature coefficient of element resistance (TCR).

Thermopile sensors are created by connecting a number of thermocouples in series, where a thermocouple is a junction between two different metals that produces a voltage related to a temperature gradient across the junction.

The T11262-01 output is proportional to incident radiation (DC coupled) and the detector features very low impedance compared to a pyroelectric sensor. This allows for simplified associated circuitry for the thermopile and less affects from extraneous radiation and electrical noise.

With the addition of a bandpass filter the T11262-01 is an ideal sensor for use in a wide range of gas analysis applications as well as in process control and security applications.
