Product Announcement from StellarNet, Inc.

For Color Transmission & Absorbance Measurement-Image

CUV1 Fiber Optic Cuvette Holder for UV-VIS - NIR

• 190 nm-2200nm Spectral Range- effective for color, transmission and absorbance measurements
• Standard 1 cm pathlength- holds 1 cm plastic, glass, and quartz cuvettes
• Fluorescence measurements- using the 90 degree pickup port and the black anodized cover (not shown)
• Flexible design- can use up to 4 fiber optic ports or a low cost option with only 2 collimators


  • The CUV1 is used for transmission, absorbance,fluorescence, and color measurements in liquids.
    Includes 2 UV grade collimating lenses.
  • The CUV2 is the same as the CUV1 but we’ve added another collimating lens.
  • Typical applications include concentration measurements, color CIELAB measurements, kinetics studies, enzymatic reactions, spectral identification, and much more.
  • Recommended spectrometer for UV-Vis measurements are: EPP2000C concave grating spectrometer 190-850nm or UVN-SR composite grating spectrometer 200-1100nm. Also works with the SL5 Deuterium + Halogen light source.
