FIELD: physics.
SUBSTANCE: coated substrate composition comprises part of glass base and part of dye for glass. The latter comprises total content of iron varying from 0.04 to 0.28 wt %, CoO content making 32 to 90 ppm, Se content varying from 1 to 5.5 ppm. Note here that CoO-to-Se content in terms of ppm equals or exceeds 6. In compliance with one version, 0.223 inch-thick glass substrate features chromacity coordinates a* varying from -3.5 to +2.5 and b* varying from -1 to -15, and radiation transmission in visible spectrum varying from 40 to 80%.
EFFECT: glass to be used in isolating blue double-glased window with thermal transmittance less than 0,40.
