Title (EN) CHALCOGENIDE GLASS MATERIAL
(FR) MATÉRIAU EN VERRE DE CHALCOGÉNURE
(JA) カルコゲナイドガラス材
Abstract:
(EN) Provided is a small-diameter chalcogenide glass material which exhibits excellent weather resistance and mechanical strength and is suitable as an optical element in an infrared sensor. The chalcogenide glass material is characterized by being a columnar chalcogenide glass material with an unpolished lateral face and a diameter of 15 mm or less, having a composition including 40 to 90% S+Se+Te in mol%, and having no striae 500 μm or longer present in the glass material.
(FR) L'invention concerne un matériau en verre de chalcogénure de petit diamètre qui présente une excellente résistance aux intempéries et une excellente résistance mécanique et qui est approprié en tant qu'élément optique dans un capteur infrarouge. Le matériau en verre de chalcogénure est caractérisé en ce qu'il s'agit d'un matériau en verre de chalcogénure colonnaire présentant une face latérale non polie et un diamètre de 15 mm ou moins, présentant une composition comprenant 40 à 90 % de S + Se + Te en % en moles, et ne présentant pas de stries de 500 µm ou plus présentes dans le matériau en verre.
(JA) 耐候性、機械的強度に優れ、赤外線センサの光学素子として好適な小径のカルコゲナイドガラス材を提供する。 側面が未研磨で、直径15mm以下の柱状のカルコゲナイドガラス材であって、組成として、モル%で、S+Se+Te 40~90%を含有し、ガラス材中に長さ500μm以上の脈理が存在しないことを特徴とするカルコゲナイドガラス材。
