[Adv.] OpTest's OpTiSurf
We have been talking about OpTest's "OpTiSurf" for some time now, for we think it is the a "signature instrument" representing all the good innovations by the fine folks at OpTest. OpTest's "OpTiSurf" is indeed a new way to measure surface roughness. According to OpTest, "The OpTiSurf revolutionizes the measurement of surface roughness of paper. Using advanced optics and algorithims, it quickly quantifies the optical roughness of entire sheets. OpTiSurf correlates with traditional air leak tests but has greater precision and speed, with less maintenance." And I would emphasize that no air is required. Answer to last week's riddle: Robert Peeler -- the terms are "Peelers" and the more familiar "bobbies"
