† - Spectral response: The response of a device to material or to monochromatic light as a function of wavelength, used to determine the sensitivity of the device. The higher the more sensitive.
‡ - Emissivity: The amount of infrared energy radiated by an object depends on its emissivity and its temperature. The emissivity depends on the material and its surface characteristics. For more accurate readings, adjust the emissivity value for the type of material being measured.
