The use of incidence at grazing angles in combination with a reduced metal thickness and incidence with a high index dielectric prism forces an impedance matching between the grating and the medium outside widening the transmit bandwidth.
Under such conditions, higher altitudes are favored to achieve higher minimum grazing angles.

This means that users may collect data at the convenient 37 [degrees] angle or select "slices" from the cone, collecting only those electrons emitted at a near-normal angle of 67 [degrees] or a grazing angle of 7 [degrees].
To get a sense of the range of nitrogen oxides (NO.sub.X.) and nitric acid produced by an extraterrestrial body in the most recent calculations, Prinn and Bruce Fegley, also at MIT, considered two kinds: a comet imparting much of its energy to the atmosphere as it comes in at a grazing angle, and an iron asteroid, which heats up less of the atmosphere as it falls nearly vertically toward the surface.
The illustrations depicting range ambiguities within the main beam footprint and tables and graphs showing grazing angles and the dependence of the clutter backscatter coefficient on the grazing angle present a picture of the complexity of this subject.
Now, two new attachments, the Grazing Angle Objective and the ATR Objective, from Spectra-Tech Inc., Stamford, CT, eliminate many of these sampling restrictions.

If the sample is oriented so photoelectrons are detected as they leave the sample at a grazing angle along the surface, then these electrons most likely originated in atoms in the top atomic layer.
