TECH NEWS: New innovation could mean more compact phones and optical gear

Scientists at Harvard University on Monday (Jan 1st) unveiled a metalens that has the potential to shrink the size of any device that uses a camera while at the same time improving performance.

While traditional lenses are made from glass, metalenses use a flat surface peppered with nanostructures to focus light. One problem with metalenses has been their inability to focus the full spectrum of light.

That’s not the case any more, however, as a team at Harvard’s Paulson School of Engineering and Applied Science have developed a metalens that can focus the entire visible spectrum of light — including white light — at a focal point, with high resolution.

    Hmmmm I see!
    Evidence is being brought forward…. knowledge is being increased both physically and spiritually but this is still not the end. More will come, but the question i always ask is, how about you? What is your decision? While the world moves forward are you increasing your knowledge in both worlds? Or are you just looking?
    What more do we need to believe?
    The dead cannot praise God. It must be done here and now! I am not looking for popularity or to be liked. I already know that i will be disliked because many who speak against these words know that they are true!
    It is just a matter of time….One day we will wake up somewhere but i pray God it will not be too late.
    Please people,be prepared!
    Praise the name of Jesus.
