14、00 O003404 b m SECTION II MEASUREMENT PROCEDURES The spectral response curves were obtained using Leitz (or equiv- alent) double monochromators. rChree instruments, equipped with calcium fluoride, sodium chloride, and cesium iodine prisms, cover the spectral region of 0.3 to 40 microns, These instru
15、ments have proven convenient to use and relatively inexpensive, and the scattered light at the third slit is very small. (With one millimeter slits and a sensitive lead sulfide detector placed at the exit slit, no scattered energy is detected beyond the long wavelength cutoff of the detector,) Each
16、instrument is equipped with an optical bench which is securely attached to the base of the instrument, in line with the exit slit. This bench supports several optical elements and a radiation thermocouple which is used as a reference detector, A first-surface plane mirror is arranged 60 that it can
17、be alternately introduced or removed from the optical path. The instruments are also equipped with entrance optics, tungsten or Nernst glower sources, and 90 Hz and 10 HZ choppers. Both choppers are placed in the entrance beam. The 90 Hz chopper is used f.or the detector channel and the 10 Hz choppe
18、r for the therinocouple channel, The complete optical ar- rangement is shown schematically in Fig, 1. (Those mirrors not common to both the reference source and the device under test must be of such quality so as not to affect the spectral transmission.) The detector electronics consist of a cathode
19、 follower mounted in the detector enclsure, a preamplifier, and a narrowband tuned amplifier having a 5 Hz bandpass and a center frequency of 90 Hz, The thermocouple signal is amplified by means of a second narrowband tuned amplifier with a center frequency of 10 Hz and bandpass of 1 Hz, St is found
20、 convenient to operate both choppers simultaneously during the measurement. The relative spectral response of the detector is calculated from where Sd-(A) = the signal from the detector. St(h) = the signal from the thermocouple, Rt.(X) = the relative spectral response of the thermocouple, The ideal
21、reference detector would have a flat spectral response, good linearity and stability, high detectivity, and a fast response time, Lacking a reference detector with these characteristics, it.is common practice to use a radiation thermocouple whose spectral characteristics have been experimentally det
