Tüüpiline neeldumisspekter (küvett läbimõõduga 1 cm - võrdluseks vesi temperatuuriga 35 oC) lainepikkus (nm) ... neeldumistegur ...
Vähemalt 10% valgusläbivus 310 nm juures (küvett läbimõõduga 1cm - võrdluseks vesi temperatuuriga 35 oC).
Glass face-plate with a diagonal measurement from the outer edge to the outer edge of 80,9 cm (± 0,2 cm]and having a light transmission of 80% (± 3 %) by a reference thickness of the glass of 11,43 mm.
It is relatively simple to have high light transmission as with a glass window, or to have high insulation as with a fiberglass-insulated wall, but it is difficult to combine these two desired characteristic.
