Abstract
A transmission cell apparatus for in-process spectroscopy comprising symmetric compound parabolic light concentrators (4, 5) terminating optical transmission fibers (8, 9) and abutting windows (2, 3) defining the sample cell.
Claims9
An apparatus for transmitting light through a sample comprising:
- a) a housing supporting a pair of parallel windows with a space therebetween in which said sample is placed;
- and
- b) a pair of symmetric light concentrators with narrower and wider ends disposed such that (I) said wider ends each abut one of said parallel windows opposite said sample space and (ii) said narrower ends each terminate an optical transmission fiber.
