In the research and development and government test range communities, the need for calibrated, scientific-grade infrared cameras has grown because of demanding, leading-edge applications such as plume and missile target signature measurements and analyses. Such IR cameras generally operate in a relatively narrow band of the electromagnetic spectrum, typically 3 to 5 or 8 to 12 μm. The spectral response across these bands is usually not flat (Figure 1). Figure 1. Typical IR camera detector materials exhibit spectral responses in the middle- and long-wavelength infrared band. PtSi =...Read full article

    electromagnetic spectrum
    The total range of wavelengths, extending from the shortest to the longest wavelength or conversely, that can be generated physically. This range of electromagnetic wavelengths extends practically from zero to infinity and includes the visible portion of the spectrum known as light.
