I was looking at the curve from this different brands and saw that so particular curve on swarovski binos !
Allbino stated that : "What’s more, its transmission decreases very quickly at extremes of the visible spectrum – such a strong decline hasn’t been observed in any of the Swarovski’s serious competitor."
His argument is a non sense because noone will see beyond Infrared.....(maybe the autor :-O, or with an IR device).
But that's not the point : Do you think swaro did it to minimise infrared transmission to retina ?
