Ocean Optics modular spectrometers and accessories can be configured for absorbance, transmission, reflectance, fluorescence, emission or scattering applications. In many setups, sampling accessories collect light or excitation energy that interacts with the sample and is transmitted to the spectrometer. Sampling accessories also include fixtures such as collimating lenses that provide specific sampling geometries. We offer nearly 500 sampling accessories for free space measurements, solid sampling and liquid sampling. Probes and accessories for Raman analysis are also available.
