title: Electro-optic high-resolution Fabry-Perot spectrometer.
abstract: A single-crystal lithium niobate dtalon suitable for high-spectral-resolution studies has been operated successfully. This étalon with a 5-cm clear diameter and a gap equivalent to 2 cm in air has been found to have very linear response in wave number as a function of voltage. The combined advantages of adjustment-free operation, linearity in operation, and high luminosity in a small size (as a result of the μ(2) gain in the instrumental throughput caused by the large index of refraction of the lithium niobate substrate) make for a rugged instrument that is ideal for long-term unattended field operation.
