Optical window assemblies

摘要

Optical window assemblies are provided. An example apparatus includes a first fixture defining a fluid flow passageway. The example apparatus also includes a second fixture defining an aperture. The second fixture is coupled to the first fixture. A first optical window is disposed in the aperture. The first optical window has a first end and a second end. The first end is to be in contact with fluid in the fluid flow passageway, and a cross-sectional size of the first optical window decreases from the first end toward the second end along a portion of the first optical window.

主权项

1. An apparatus, comprising:
a first fixture defining a fluid flow passageway; a second fixture defining an aperture, the second fixture coupled to the first fixture, the aperture having a tapered shape extending between a first portion of the aperture adjacent the fluid flow passageway and a second portion of the aperture positioned to receive a fiber bundle, the second portion having a smaller cross-sectional size than the first portion; a first optical window disposed in the aperture, the first optical window having a first end and a second end, the first end to be in contact with fluid in the fluid flow passageway, wherein a cross-sectional size of the first optical window decreases from the first end toward the second end along at least a portion of the first optical window such that a tapered shape of the first optical window fits the tapered shape of the aperture and thus blocks removal of the first optical window in a direction toward the fiber bundle while enabling force applied to the first optical window via the fluid to be transferred to the first fixture; a second optical window in optical communication with the first optical window via the fluid flow passageway; and a third fixture defining an aperture to receive the second optical window, the third fixture coupled to the first fixture.
