  • Emissivity Correction for a Radiometer
    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, reflectance r, and transmittance t. For a Lambertian type surface they are related by Kirchoff 's law.
  • Microwave Radiometer Systems: Design and Analysis, Second Edition
    Microwave Radiometer Systems: Design and Analysis, Second Edition. Written by leading experts in industry and academia, this authoritative resource offers a solid understanding of radiometer systems and explains how to design a system based on given specifications, such as technical aspects
  • Variations in Calibrations of Radiometers Using Cut-on Optical Filters
    The spectral bandpass of infrared radiometers using thermopile detectors are often controlled with a 6 um cut-on filter. These filters normally have a cut-on tolerance of +1 um and the cut-off wavelengths are determined by the substrate transmission, which is usually germanium or silicon
  • A Simple DC Radiometer
    One of many applications of the thermopile detector is the remote measurement of temperature. In this Application brief we explain the basic principles of remote temperature measurement. Every object at temperature T (above absolute zero - 273.15 C) emits electro-magnetic radiation. The total
  • Temperature Compensation of a DC Radiometer
    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. The later is usually difficult to implement in an instrument because of size and weight requirements.
  • Spectral Selectivity vs. Spectral Error: Shedding Light on ISO 9060:2018
    In late 2018, the ISO 9060 standard for solar radiometers underwent a remarkable update that brought significant changes on the classification of solar radiation measurement quality. At first glance, ISO 9060:2018 appears to be mainly a renaming of radiometer classification launched in the original
  • Ventilation Case Study in Finland
    Kipp & Zonen radiometers were used for a case study in Finland on the effects of different types of ventilation units on keeping pyranometers clean, especially in the winter conditions of snow and rain showers, freezing rain, frost and other situations. This initial review of the case study results
  • Thermal Response Characteristics of Marine Grade Radome Composites Designed for use on Spruance Class Naval Destroyers
    FLIR radiometers. The front face surface temperature of the sandwich structure was measured with a cooled shortwave (3-5 um) radiometer (Merlin MWIR ). The corresponding response of the sandwich composite's back face was measured with a Thermacam 290. Additionally, K type thermocouples were bonded
