Abstract

An improved apparatus for diffuse re-flectance spectroscopy having a specular con-trol device. The specular control device has at least a first surface divided into an even--numbered plurality of reflecting sections (112, 114) and open or transmitting sections (116, 118). The number of reflecting sections is equal to the number of open sections. Each reflecting section is situated between a pair of open sections and opposite to another reflect-ing section. Similarly, each open section is situated between a pair of reflecting sections and is opposite to another open section. In one preferred embodiment, the total surface area of the reflecting sections is equal to the total surface area of the open sections. In an-other embodiment, the total surface area of the reflecting sections is unequal to the total sur-face area of the open sections. In another pre-ferred embodiment, opaque spacers (111, 113) are provided on the borders between adjacent sections to improve the detecting definition be-tween source and reflected beams, and to se-lectively provide (115, 117) for decreasing sur-face area of one or more selected sections.
