What is a Spectrometer? A spectrometer is an instrument used to measure and analyze light as a function of wavelength. By separating light into its individual wavelengths, a spectrometer can reveal information about the composition, properties, and behavior of...

Raman probes are devices that use fibers to deliver the excitation laser beam to the sample and collect the signal, allowing for more flexibility with the sample holder. Raman probes can be adjusted to have additional probe tips for adjusting working distances as well...

Reflectance probes are fiber bundles designed to deliver the light source to the sample and collect signal that is reflected back. Six or seven fibers in an outer ring are used to illuminate the sample and one fiber in the middle collects the signal. These probes are...

Flow cells are sample cells designed so that liquid samples can be continuously flowed through the beam path. This is useful for samples that can be damaged by the light source. New sample is continually replenished so that the damage does not interfere with the...

Dip probes are a probe that allows you to perform liquid absorbance and transmittance measurements without a cuvette. The probe is dipped straight in the liquid sample and the measurement happens at the gap in the tip. A fiber delivers the light source to the tip and...
