Characterization of an Acousto-optic tunable filter for development of a near-IR spectrometer for planetary science

Agrawal, Prince; Nandi, A.; Sudhakar, M. +4 more

The development of a spectrometer is being carried out in the Near-Infrared (NIR) wavelength range of 1.0-1.7 µm using an Acousto-Optic Tunable Filter (AOTF). The AOTF is based on Tellurium-di-oxide (TeO₂) crystal that acts as a dispersing medium and is driven by an external Radio Frequency (RF) signal. The characterization of AOT…
