Low dispersion infrared glass |
摘要 |
The present invention teaches infrared chalcogenide glass compositions having very low dispersion in the eight to twelve micron range, which are formed as III-V-VI-VII compositions, e.g. 14% (atomic) gallium plus 25% antimony plus 40% selenium plus 21% bromine. The introduction of a group VII component into a chalcogenide glass provides low dispersion, and the group III component compensates for the strong devitrification tendencies of the group VII component and maintains the mechanical properties of the glass.
