Ocean Optics sampling accessories are designed for fiber optic coupling to the spectrometer or from a light source. Sample accessories range from liquids (standard cuvettes), diffuse or specular reflecting solid materials, cosine correctors (diffusers) and collimation lenses for light sampling (e.g., lighting, plasmas...). If you have a unique application where a simple off the shelf accessory will not work, contact us (via email here, or 651-407-9582).
