Abstract
A spectrophotometric system includes an optical device for providing an optical path from a radiation generating means to a radiation receiving means. The optical device includes a substantially opaque layer which defines first and second coplanar face regions having different optical functions.
Claims11
A spectrophotometric system comprising:
- photometric optics including means for generating photometric radiation;
- radiation receiving means is spaced relation with said radiation generating means;
- an optical device, interposed between said radiation generating means and said radiation receiving means, for providing an optical path from said radiation generating means to said radiation receiving means, said optical device comprising;
- a substantially opaque layer, said layer defining at least first and second coplanar face regions, said face regions having distinguishable optical functions being arranged in a predetermined geometrical relationship;
- means for supporting said layer, said means being a rigid substrate;
- a film bonding agent, between said layer and said rigid substrate means, for permanently maintaining said predetermined geometrical relationship, and
- means for mounting said optical device for movement between different operative positions to selectively interpose said face regions between said radiation generating means and said radiation receiving means.
