Customer Testimonial

Sophinese Iskander-Rizk first obtained the degree of electronics engineering at the American University in Cairo and then joined Delft University of Technology to pursue a master’s degree in biomedical engineering. She then joined in 2014 the biomedical engineering department at Erasmus MC, university medical center in Rotterdam to pursue a doctoral degree on biomedical imaging. Her research topic is photoacoustic imaging for cardiovascular application.

I have used an OPOTEK Vibrant tunable laser to perform a wide range (410 nm to 1000 nm) photoacoustic spectroscopy on tissue. This resulted in very nice images, which are published in:

One of the most practical features of this laser is its optical energy output, pulse duration, which make it suitable for photoacoustic imaging, as well as the capability of control via MATLAB, and external triggering and delaying functionalities which make it easy to integrate in an experimental setup.
