A "Kaesemann" Polarizer is simply a more durable polarizer. Select foils, specially prepared optical glass, hermetically sealed. But it is still a regular old polarizer. All of my Heliopan polarizers are "not" Kaesemann polarizers and they "all" have numbers around the rim. This is a Heliopan standard feature. I do have a Kaesemann polarizer, in 82mm. It has no numbers around the rim. Jim At 03:27 PM 2/17/99 -0800, you wrote: >Hi Jim, > >I could be wrong, but I believe the numbering is found on what are called >Kassemann polarizers.
