The CUV-UV test tube holder can be used with 10-cm optical path length test tubes, and can be coupled via SMA-connector fibers to Ocean Optics high-sensitivity miniature fiber optic spectrometers and light sources, forming a miniaturized spectrophotometer system for absolute absorbance measurements of various aqueous solutions and gases. This compact test tube holder is optimized for UV-VIS-NIR (~200 nm-2 µm) applications. Using the 10-cm test tube holder is simple: connect two collimating lenses to SMA-connector fibers respectively, one fiber—the illumination fiber—coupled to a fiber-output light source, and the other—the read fiber—connected to the spectrometer. In some cases, you can adjust the collimating lenses to precisely position the fibers at the focal point of the lens. "Z" Dimension: The "Z"-direction dimension of all test tubes and test tube holders provided by Ocean Optics is 15 mm. User Tips: The 74-series collimating lenses are very common components for test tube holders and can be unscrewed from the holder and used independently for any device requiring free-beam coupling into a fiber, such as in-line transmission or reflection measurements.
