Description: The PerkinElmer LS 55 Luminescence spectrometer offers flexibility, versatility, reliability and ease-of-use. Based on years of experience in Luminescence spectroscopy, the LS 55 spectrometer includes a host of automated accessories and software to address a wide range of bioresearch applications. The monochromator based LS 55 uses a high energy pulsed Xenon source for excitation. The variable slit and holographic gratings provide flexibility with very low stray radiation. A reference signal system has been added to provide users with much more control over signal dynamics. This is particularly useful for samples with widely differing intra-sample signal size.


  • The LS-55 is a fluorescence/luminescence spectrophotometer with pulsed high pressure Xenon source. 
  • It is equipped with monochromators on both the excitation and emission sides and is capable of both excitation (200-800nm) and emission (200-900nm) scans. 
  • Possible to measure thin films, powders or liquids
  • The sample mount does not have any temperature control capability.
