Evaluation of photo-stimulation intensity dependence is often a necessary part of neuro-modulation experimentation utilized in optogenetics studies. The inherent stability and quantitative nature of Lumencor’s SPECTRA X Light Engine make it particularly well suited as the pulsed light source of choice for studies requiring pulse width and frequency of stroboscopic illumination analyses. Find more detail regarding this stable, reproducible, well-behaved data and the light engine that produced it, as well as a specific reference in a recent Journal of Physiology publication by authors Kubota, Sidikejiang, and Seki, on Lumencor’s website.
