What is a Cosine Receptor?

A cosine receptor (sometimes called a cosine corrector) is a type of light receptor that is used for radiometry and photometry. It collects all light in a 180 degree field of view, making it suitable for measuring light from a planar surface or light from multiple...

What is a Spectroscopy Blank?

A blank is a sample that contains everything except for the analyte of interest. For example, if you are doing a UV-vis experiment to measure concentrations of Green Fluorescent Protein, the protein has to be dissolved in a solvent. The blank is a sample of just the...

What are Raman Probes?

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...

What are Reflectance Probes?

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...
