The core provides service in optical measurements in solution and solid form. The Core has several state-of-the-art spectroscopic instrumentation.

In 2012, the lab installed a unique fluorometer designed for research in Vis-NIR spectral range (300-1600 nm). The instrument was purchased from funding provided by NIH (S10 Shared Instrumentation Grant). This custom-designed system built by Horiba Jobin Yvon Inc. is one of the most sophisticated fluorescent spectrophotometers in the world.

In 2015, the lab installed a new imager in shortwave infrared
