*Clusters with UV LED's are available at higher cost
An OLIS LED7 is an excellent choice for experiments requiring an actinic source or fluorescence excitation.
A pair of LED7 clusters are available to produce the absorbance measurement beam in the CLARiTY VF model.
Each LED can be controlled with sub-microsecond precision (independently) for the duration required, with nearly limitless scripted options possible.
Changing clusters takes moments and no tools, so a given laboratory might own various clusters to support an array of experiments.
A bandpass filter can be used for refinement of the light with any cluster.
For fluorescence, choose an appropriate cluster or filter to obtain the appropriate excitation wavelength(s).
