From this Article:
Dexter Research offers a wide variety of package hole sizes and internal apertures which can be used to modify the Field of View (FOV) of single element detectors or minimize cross talk in...
(Temperature Sensing)
From this Article:
The selection of encapsulating gas in a thermopile detector package affects four important performance parameters: the output voltage, responsivity, signal-to-noise ratio (SNR) and time constant....
(Temperature Sensing)
From this Article:
The radiant power received by a radiometer is not only a function of the measured target temperature, but also the optical properties of its surface. These properties include absorptance a,...

From this Article:
All solid bodies that have temperatures above absolute zero (0 Kelvin, -273°C) emit electromagnetic waves. The thermal radiation portion of this energy is called infrared radiation. Wien's...

From this Article:
Dexter Research Center is a leader in the manufacture of stable, high quality, high output radiation sensing thermopile detectors with a linear dynamic range from the UV to long wave IR. Thermopile...
(Temperature Sensing)
From this Article:
The thin film thermopile detector like its forefather, the wire thermocouple, requires either a reference junction temperature measurement or a constant temperature sink for its reference junction....
(Temperature Sensing)
From this Article:
To make a radiometric measurement with thermopile detectors, you will need to approximate the thermopile's cold junction temperature. Dexter offers optional externally mounted thermistors for all...
(Temperature Sensing)
From this Article:
The benefits and advantages of thin film detectors vs. silicon detectors....
(Temperature Sensing)
From this Article:
The time constant of thermopile detectors can be determined by several methods depending on the specific waveform of the radiation used to excite the detector. If the detector is subject to a step...

From this Article:
The spectral bandpass of infrared radiometers using thermopile detectors are often controlled with a 6µm cut-on filter. These filters normally have a cut-on tolerance of +1µm and the cut-off...
