Abstract

An optical system is designed to form real images of both its field and aperture stops 21 and 22 at the two window boundaries 13 and 14 of the path through a cell 11. This dual stop imagery permits control of both size and shape of the illuminated space. If this space is made cylindrical, its volume equals the exact fundamental minimum required to transfer the available light flux over a given path length, without reliance on wall reflections. A marginal concentric clearance of the cell bore around the illuminated space serves to avoid interferences from the wall and any adjacent perturbed liquid layer. The embodiment shown is an analytical apparatus for detection of optical absorption in liquid chromatography and cell 11 is tubular and has an entrance 15 and exit 16 for flowing liquid. Hemispherical and hyper - hemispherical lenses may be used. <IMAGE>
