Sources lumineuses avec filtre de verre en terre rare. Il existe [...] des instruments pour lesquels l'utilisation des raies de deutérium n'est pas valable. Aussi quelles autres options existe-t-il? Une des possibilités les plus simples est d'ajouter un filtre standard constitué de verre en terre rare, par exemple de la silice mélangée avec un oxyde terreux. On utilise en général l'holmium qui donne des bandes d'absorption comprises entre 241 et 637 nm, ou le didymium (573 à 803 nm). 1, record 1, French, - verre%20en%20terre%20rare

Positioning of the SOFIA telescope is based on spherical sensors(position sensitive devices, PSDs), located at the bearing, and an high resolution inertial three laser gyro system, which is updated regularly by the focal plane tracker camera. The gyros were specially developed for SOFIA to provide extremely low drift rates and noise. Each of them includes 3km of glass fiber providing an angular increment of 0. 0008". 2, record 3, English, - angular%20increment
