Abstract

The infrared reflectance of water at incidence angles of 70° and 75° has been measured in the spectral region between 2 and 25 µm. We have used the measured reflectances of polarized radiant flux to determine the real part of the refractive index from the Fresnel equations. The imaginary part of the refractive index can be accurately determined from reflection measurements alone only in regions of strong absorption; in other regions we have used values based on measurements of transmittance. We give values of the optical constants in tabular form and compare them with recent determinations by other investigators.

  10. Tests show that the normal-incidence reflectance of uncoated aluminum mirrors from commercial sources gradually increases from 0.94 at 2 µm to 0.975 at 15 µm. Small absorption bands were noted at 8.5 µm for commercially aluminized mirrors.

  12. In the course of their work, Pontier and Dechambenoy relied on the use of amplifier-gain steps in measuring R and made no corrections for polarizer leakage and spectrograph discrimination. Because the angles of incidence used in the studies of polarized flux were close to Brewster's angle, the latter two corrections were unnecessary.
