  • Patent number: 5526194
    Abstract: An optical element support for supporting optical elements adjacent to a lens of a camera. The support comprises an optical element holder assembly which is mountable to the camera lens housing. The holder assembly includes at least one stack of discrete holder members configured so that adjacent ones of the holder members together define grooves therebetween to hold a desired selection, by number and dimension, of optical elements. The holder members are removably connectable and further configured such that a rearrangement of the holder members in the stack permits variation in the number and/or width of the grooves and the accommodation in the grooves of optical elements of different number and/or thickness.
