DESCRIPTION
This triangular cell is used for measuring stray light when filled with concentrated Rhodamine 101, which is effectively used as a filter for stray light measured at 240 nm and 300 nm. Stray light can be broadly defined as light which is present in the beam of wavelengths other than those chosen by the user. One of the biggest potential sources of stray light is white light which is generated by the intense xenon source (either pulsed or continuous) which "steeps" past the excitation monochromator and manifests itself as stray light. This can cause spectral artefacts, such as small shoulders or similar features on spectra.
