With small working distance, it allows to use lenses with large numerical apertures and thus to collect a maximum of signal very suitable then for very small samples (even for individual nano-objects as in the article) or samples that give a weak signal.
A collaboration between BETSA® and the UCBL
A NEW "NANO" Membrane Diamond Anvil Cell is available,
to achieve a new objective, a minimal working distance, a lightness and a maximized angular opening.
This NANO MDAC has been developed by the UCBL and now available in partnership sign with BETSA® Company.

spectroscopy microscope and an ultraflat diamond anvil cell, allowing us to quantitatively investigate the high-pressure optical extinction spectrum of an individual nano-object. A large tuning of the surface plasmon resonance of a gold nanobipyramid is experimentally demonstrated up to 10 GPa, in quantitative agreement with finite-element simulations and an analytical model disentangling the impact of metal and local environment dielectric modifications. High-pressure optical characterizations of single nanoparticles allow for the accurate investigation and modeling of size, strain, and environment effects on physical properties of nano-objects and also enable fine-tuned applications in nanocomposites, nanoelectromechanical systems, or nanosensing devices.
