Paper Abstract

Certain glasses in the As-S and As-Se binary and As-S-Se ternary systems satisfy the challenging combination of optical and physical properties that describe an athermal solid Fabry-Perot etalon. This means that, in the investigated temperature range (roughly 25-35oC), interference fringes undergo very little movement in resonant wavelength as the temperature changes (i.e. < 5 ppm/K). Further, by virtue of their unusual combination of properties, this suite of glasses will occupy unique coordinates in the “glass map” approach used by optical designers to fabricate thermally- and chromatically-corrected lens systems.
