NPC Standard Pellicle Frames are stocked in 1",2",3",4",5" and 6" circular rings, plus 5"x7" rectangles. Top surfaces are beveled. The frame is black anodized, then lapped to create a flat at the inner edge.
The membrane is then stretched over the flat and firmly adhered to the beveled area. The machined aluminum rings have two threaded mounting holes on the back.
National Photocolor offers seven (7) standard frames and we routinely mount pellicles on custom frames. Frames, which should be designed in conjunction with NPC, may be supplied by the customer or National Photocolor. Frequently, a frame can be quickly and inexpensively supplied from our large inventory of special frames.
Custom pellicles have been made from 1/16" I.D. to 16" I.D. In addition to circles and rectangles, ellipses and truncated cylinders (tubes cut off at an angle) are used for their ability to pass a circular beam at 45°
