[Denglas Technologies Inc] A registered trademark (2006) for a nonreflective coated Glass. Denglas® antireflective glass has a sol-gel coating that eliminates glare and provides better UV protection than uncoated glass. Denglas® sheets have a slight purplish color. The coating can be damaged by cuts and abrasion. Denglas® is used as a matte glass for glazing paintings.
As of 2022, no websites were found for Denglas, but the Trademark company (Denton Vacuum) still makes optical thin films.
