Lauretta, The OSIRIS-REx Visible and InfraRed Spectrometer (OVIRS): Spectral Maps of the Asteroid Bennu, Space Science Reviews, 2018, submitted The OVIRS instrument paper. OVIRS Spectrometer The OSIRIS Visible and near-IR Spectrometer (OVIRS) is a point spectrometer with a 4-mrad field of view (FOV) that provides spectra over the wavelength range of 0.4 – 4.3 μm to map the visible and near infrared characteristics of the surface of the asteroid (101955) Bennu. It employs wedged filters (also called a linear variable filter) to provide the spectrum. A wedged filter is a two-dimensional spectral filter in which the wavelength of transmitted light varies in a well-defined fashion with position along one of the spatial dimensions.
