Ultra low noise light source from Prizmatix

by Kathrin Beckstein

In many scientific applications, very small changes in measured parameters are of great importance. For example, tiny changes in fluorescence may be evidence of significant changes in a biological system.

So in order to detect the tiny changes in the optical signal, the light source must be a “Low Noise” source, making sure that the signal change seen is not due to variations in the illumination, but a real change of the system observed.
Prizmatix has developed Ultra Low Noise light sources, based on the fiber-coupled Silver-LED. These Ultra Low Noise light sources achieve a Relative Intensity Noise (RIN) as low as 0.007% in peak-to-peak consideration and even 0.0008% when considering the root mean square of the noise.
