Lot of miscellaneous optics, filters, for laser (?)

I have no clue what these are for.
I got this stuff years ago at a flea market. Seems to be a bunch of Optical items.
My friend says they are laser filters and splitters(?). Theres about 30 or more pieces in general.
I recognize lenses, in the little pouches. Theres a lot of little things wrapped in tissue paper.
I figured i'd better leave them wrapped up, instead of unwrapping them for pictures.
