WebJan 1, 2016 · For wedge-shaped hoppers, the width of the slotted outlet must be large enough to prevent a cohesive arch from developing. The same procedure that is used to determine the minimum outlet width to prevent arching in a wedge-shaped mass–flow hopper is followed, except that a flow factor of 1.7 is used. WebThe flatness of an optical flat is measured in fractions of a reference wavelength, 632.8nm. A λ/20 flat will have a maximum peak to valley deviation of 632.8/20 or 31.64nm. We offer several levels of flatness for our single surface flats: λ/4, λ/10, and λ/20. For our dual surface flats, ¼, 1/10 and 1/20 flatness are available.
