Claims
- 1. 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.
- 2. The apparatus of claim 1 wherein said housing provides ingress and egress ports in fluid communication with said space between said parallel windows f o r circulation of sample fluids there through.
- 3. The apparatus of claim 2 further comprising at least one circumferential channel for facilitating said circulation.
- 4. The apparatus of claim 1 further comprising a fitting for a heating element.
- 5. The apparatus of claim 1 wherein said symmetric light concentrators are compound parabolic concentrators.
- 6. The apparatus of claim 1 wherein said symmetric light concentrators are conical concentrators.
- 7. The apparatus of claim 1 wherein said windows are zinc selenide.
- 8. The apparatus of claim 1 wherein said windows are barium fluoride.
- 9. The apparatus of claim 1 wherein said windows are diamond.
