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.

The FL 8500 fluorescence spectrometer uses a high-performance continuous wave excitation source with PerkinElmer optics for high sensitivity measurements at scan speeds up to 60,000 nm/min. The FL 8500 is the choice when sensitivity and/or scan speed is most important. The FL 8500 solution can be configured for a range of applications including: material characterization, industrial dye, printing, and tracing manufacutring and R&D, and environmental analysis of LEDs, solar cells and organic electroluminescent materials. The FL 6500 fluorescence spectrometer uses a pulse excitation source with variable power settings desigend for samples susceptible to photo bleaching. The FL 6500 system can be configured for a range of applications including cell biology, molecular biology, immunology, enzymology and protein analysis and thin coatings. Together, these instruments create a comprehensive fluorescence portfolio enabling customers to tackle most application challenges.
