SCHOTT-Desag B270 Crown Optical Glass
The Formatt Hitech HD ND 0.9 Glass Filter, made with SCHOTT-Desag B270 Crown optical glass, has been specially formulated as a result of extensive research into applications for molecular A.C.T. dyes. The filters give more of a neutral gray without the specular effects from the particulate coatings of the current neutral density and neutral density graduated filters, which allows the user more precise control.
