Description
UV-Vis cuvette holders are essential optical sampling accessories used in absorbance, transmission, and fluorescence spectroscopy systems. These holders enable stable positioning of standard cuvettes while coupling spectrometers and light sources through SMA 905 fiber-optic connections for accurate liquid-sample analysis across UV, visible, and near-infrared wavelength ranges.
The Ocean Optics cuvette holder family includes multiple configurations optimized for different spectroscopy workflows, including standard 1 cm absorbance measurements, long-pathlength transmission analysis, fluorescence spectroscopy, and compact fiber-coupled OEM integration. Designed for compatibility with miniature fiber-optic spectrometers and spectroscopy light sources, these holders support flexible laboratory and embedded optical measurement setups.
The CUV-UV model supports standard 1 cm cuvettes for UV-Vis absorbance measurements of aqueous and chemical samples, while the CUV-UV-10 extends optical pathlength to 10 cm for low-concentration absorbance and gas-transmission applications. For fluorescence workflows, the CUV-FL-DA direct-attach holder enables highly compact measurement configurations optimized for relative absorbance and fluorescence experiments over a broad 200–2000 nm wavelength range.
The SQ1-ALL Square One cuvette holder adds additional flexibility through integrated collimators, filter holders, and multi-port optical access for more advanced spectroscopy experiments. Optional mirror screw plugs further enhance fluorescence signal collection by redirecting excitation and emission energy back into the optical path.
These UV-Vis cuvette holders are suitable for a wide range of spectroscopy applications including chemical analysis, life-science measurements, fluorescence detection, optical sensing, environmental testing, and OEM spectrophotometric system integration.
