Title (EN) NEAR INFRARED RAY ABSORBING GLASS
(FR) VERRE ABSORBANT LES RAYONS PROCHES INFRAROUGES
(JA) 近赤外線吸収ガラス
Abstract:
(EN) Provided is a near infrared ray absorbing glass which enables thinner optical devices and has excellent weather resistance, devitrification resistance, and optical properties. The near infrared ray absorbing glass comprises, in cation%, 10 to 70% P5+, 0 to less than 7% Na+, 3 to less than 31% R2+ (R is at least one selected from Mg, Ca, Sr, and Ba), 0.1 to 20% Mg2+, 2 to 20% Sr2+, and 0.1 to less than 9% Cu2+, and in anion%, 14.5 to 90% F- and 10 to 85.5% O2-, and is characterized by having a thickness of 0.25 mm or less.
(FR) La présente invention concerne un verre absorbant les rayons proches infrarouges qui permet des dispositifs optiques plus fins et présente d’excellentes résistance aux intempéries, résistance à la dévitrification, et propriétés optiques. Le verre absorbant les rayons proches infrarouges comprend, en % de cations, de 10 à 70 % de P5 +, de 0 à moins de 7 % de Na+, de 3 à moins de 31 % de R2+ (R étant au moins l’un sélectionné parmi Mg, Ca, Sr, et Ba), de 0,1 à 20 % de Mg2+, de 2 à 20 % de Sr2+, et de 0,1 à moins de 9 % de Cu2+, et en % d’anions, de 14,5 à 90 % de F- et de 10 à 85,5 % de O2-, et est caractérisé en ce qu’il présente une épaisseur de 0,25 mm ou moins.
(JA) 光学デバイスを薄型化でき、かつ、耐候性、耐失透性及び光学特性の各特性に優れた近赤外線吸収ガラスを提供する。 カチオン%で、P5+ 10~70%、Na 0~7%未満、R2+ 3~31%未満(RはMg、Ca、Sr及びBaから選択される少なくとも1種)、Mg2+ 0.1~20%、Sr2+ 2~20%、Cu2+ 0.1~9%未満、及び、アニオン%で、F 14.5~90%、O2- 10~85.5%を含有し、厚みが0.25mm以下であることを特徴とする近赤外線吸収ガラス。
