The CUV-FL-DA cuvette holder attaches to Ocean Insight light sources and couples via optical fiber to our spectrometers, creating a small-footprint system for fluorescence and relative absorbance experiments. The CUV-FL-DA is optimized for the 200-2000 nm range, holds 1 cm pathlength square cuvettes and eliminates the need for a fiber from the excitation or illumination source. A few simple adjustments allow you to use the CUV-FL-DA for absorbance.

The CUV-FL-DA is well suited for fluorescence, thanks to UV-enhanced, aluminum-coated mirrors that enhance signal reflection within the sample compartment. That increased signal reflection, combined with greater signal intensity resulting from direct attachment to the excitation source, provides CUV-FL-DA users with much greater fluorescence intensity than is possible with most cuvette holders.


  • No excitation or illumination fiber – sample cell attaches directly to light sources
  • Enhanced fluorescence – optical design increases signal collection
  • Versatile – simple adjustment converts from fluorescence to absorbance accessory
