Laboratory of Hybrid Nanophotonics and Optoelectronics

 

Photocor Complex are based on the static and dynamic light scattering(photon correlation spectroscopy). This technique is ideal for measurements of nanoparticle size, diffusion coefficient, and molecular weight of polymers in solutions. A traditional design of the Photocor Complex is optimal for a wide range of applications: from simple industrial tests to the most advanced research tasks. Measurement procedure and powerful software are suitable for any level of users.
