Circularly polarized luminescence (CPL) is vital for emerging technologies in optics and display design, but generating it with both efficiency and full-spectrum color remains a challenge. Quantum dots provide tunable brightness across the visible range but emit unpolarized light. Chiral cellulose nanocrystals (CNCs), by contrast, offer a structured, bio-derived platform for controlling light polarization. When combined, they form a system capable of transforming color-rich emission into precisely polarized output.

Cholesteric-superhelix films have captivated scientists and engineers with their ability to manipulate light in precise and tunable ways. Their complex internal architectures, defined by a hierarchy of helical structures, offer exciting potential for applications ranging from optical sensing to secure data storage. Yet, truly understanding such intricate materials requires a method that can reveal their hidden chiral features without altering or damaging them. Circularly polarized luminescence (CPL) from upconversion nanorods provides a practical method for examining the films’ internal helical formations in detail, offering new insight into how these materials function and respond.
Metasurfaces function through carefully patterned nanostructures, each smaller than the wavelength of light. These engineered features are designed to manipulate light in precise ways, influencing properties such as phase, polarization, and spectral response. Unlike traditional optical components, metasurfaces provide this level of control in a compact format that can conform to varied shapes and structures.
Because of their precision and versatility, metasurfaces are being developed for a wide range of applications, including imaging, sensing, filtering, and display technologies. As designs become more advanced and performance requirements increase, it is essential to comprehend how these structures interact with light at the microscale.
To support this understanding, microscale metasurface characterization focuses on analyzing the optical behaviour of the structures themselves. Detecting subtle variations in performance, often across individual or closely spaced features, requires high spatial resolution. Specialized tools provide the level of precision needed by capturing fine structural detail alongside localized optical effects, enabling researchers to determine how fabrication results align with intended design.
Curved optical components are central to modern optical systems. They enable wide fields of view, compact lens assemblies, and precise control over light paths. But their geometry introduces a unique challenge: verifying that antireflection (AR) coatings perform consistently across the entire surface.
Unlike flat optics, curved surfaces vary in both angle and shape. As the geometry changes, so do the conditions under which light interacts with the coating. This can lead to shifts in reflectance, inconsistencies in thickness, and localized performance deviations that aren’t visible using conventional measurement tools.
Microspectroscopy makes it possible to characterize these coatings in detail. It provides localized spectral and material data, offering a clear view of how the coating behaves at each microscopic point across the surface. With the right microspectrometer, you can move beyond assumptions and measure AR coatings where they matter most — in the form they’re used and under the conditions they face.
