Steady-State Fluorescence/ Photoluminescence System
 
Fluorescence & Photoluminescence occur when a sample is excited by absorbing photons and then emits them with a decay time that is characteristic of the sample environment. Fluorescence is a term used by chemists when the absorbing and emitting species is an atom or molecule. Photoluminescence is the term physicists use to describe the absorption and emission of light by things such as semiconductors and nanotubes. Regardless of the terminology, when samples absorb photons and then emit them at a different wavelength the resultant light can be dispersed by a spectrograph, the spectrum can be detected by a device such as a CCD, and information can be gleaned about the sample

OmniFluo Photoluminescence(PL) Basic Configuration


OmniFluo Photoluminescence(PL) System can realize the PL/PLE fluorescence spectra measurement. This system solves the energy shortage problem effectively for some experiment using Xenon lamp as the excitation light source. And you can add the sample temperature controllers for ultralow temperature testing condition, which is very convenient for rare earth luminescent material luminous performance research.
