Descripción
For the Visible Light Imager and Magnetograph (VIM) a high-resolution
filtergraph is under design. The system takes advantage of a lithium
niobate (LiNbO3) crystal which can be used as a scanning filter using
high voltage for tuning. We have undertaken first studies to qualify a
lithium niobate wafer of 70 mm aperture size for deployment and use in
space. We show the results of the mechanical mounting and vibration and
thermal cycling tests as well as stability tests under fast voltage
tuning in vacuum. Although these tests have all been very successful,
further environmental testing is necessary to fully space-qualify the
filter for the Solar Orbiter mission.
