Cryogenic refractive indices for S-FPL55, S-LAL8, and S-BAH28 glasses for the HARMONI visible camera
Abstract
This paper reports on absolute refractive index measurements for the S-FPL55, S-LAL8, and S-BAH28 glass materials that are used in the visible channel of the HARMONI integral field spectrograph of the Extreme Large Telescope (ELT). These measurements were carried out by using the world-class Cryogenic High Accuracy Refraction Measurement System (CHARMS) refractometer (located at the Goddard Space Flight Center) in the 0.420−3.5 μm wavelength …
