Light is all around us, and scientists are always finding new ways to study it. Recently, they've made a big step forward with tiny lenses that can do what big, bulky machines used to do. These tiny lenses, called metalens arrays, can now look at light in a way that tells us a lot about its properties.

The new tech uses a special material called TiO2 to make these tiny lenses. They are arranged in a pattern that looks like a hexagon. This setup lets them focus on six different parts of light at the same time. This is a big deal because it means they can give us a complete picture of light's behavior in just one look.

But how well does it work? The system can figure out light's polarization state with a tiny error margin of just 4. 64%. It can also measure how light's phase changes, with a maximum of 1. 75 rad/μm. This is important because it means the system can accurately describe complex light patterns, like those seen in radially or azimuthally polarized vortices and diverging wavefronts.

The best part? This new tech is compact. It can fit in small spaces, making it perfect for use in tight spots where big machines can't go. This could be a game-changer for fields that need to study light's properties, like adaptive wavefront control and quantum optical characterization.

But it's not just about the tech. It's about what it can do. This system could open up new possibilities for studying light in ways we've never seen before. It's a big step forward in the world of optics, and it's all thanks to these tiny lenses.
