CUV-10-4-WAY is a cuvette sample holder with four-side optical access. It integrates four collimators and uses SMA905 fiber interfaces. Coupled with Oceanhood Taiwan’s’ fiber spectrometers and light sources, it supports multiple measurement modes, including absorbance/transmittance, reflectance, and fluorescence. A professional light-tight cap is included to block ambient light and ensure accurate results. Optional filters across different wavelength bands can be installed for fluorescence testing. Filter size requirement: Ø8 mm, thickness ≤ 2 mm.
