Concentric Arrays of Ring Shaped Apertures as Neutral Density Filters
Keywords:
Curves, Neutral Filter
Abstract
Neutral density filters with flat transmission curves find extensive use in optical instruments, but really neutral filters i.e., with flat transmission are rather difficult to fabricate. A new method of making neutral filter has been discussed here from the oretical as well as practical aspect.
