Description
Biconical FTIR reflectance spectrum of the <25 micron size fraction OREX-800091-102 made by dry-sieving the angular rock OREX-800091-0 of asteroid Bennu was measured using Thermo Nexus 870 FTIR spectrometer with PIKE biconical diffuse reflectance accessory having a gold-coated mirror. The incidence and emergence rays are conically shaped. The incidence and emergence rays are off the plane perpendicular to the sample surface, and they are cone-shaped centering around 30 and -30 degrees from the vertical axis.
