When you need a glass of wine, a new invention from a Harvard professor could save you
- by admin
Glasses and glasses of wine are an iconic part of our modern lives, and the world is slowly starting to change its attitude toward them.
Harvard’s Robert Califf has developed an entirely new form of glass, called the pulis.
He explains the idea in this interview.
“If you look at the world around us, it seems like everybody is wearing glasses,” he says.
“I want to see if there’s a way to make glasses that don’t need glasses.”
Califf, a professor of electrical engineering, has invented the pulisphere, which uses a metal plate to absorb light, and he’s worked on it for over a decade.
His invention works by using a “tear” on a glass plate, which allows light to pass through the plate, instead of the glass itself.
When you look through the lens, light passes through a thin layer of material, called a microlens, which acts like a diffuser to filter out any unwanted light.
When the glass is placed on top of the microlenses, the light passes freely through the glass.
“It works very well because the micro-lens has a large amount of light and a small amount of reflection,” Califf says.
The idea of the puli is that instead of taking a picture of a glass, the micro lenses will absorb light and send it out.
This is what Califf is referring to when he says that he has invented a new kind of glass that has a micro lens that acts like the micro lens of a microscope.
“You can get a picture with this, and it will give you an idea of what the object is,” Calff says.
The puli uses a simple method of manufacturing: a sheet of plastic and metal are combined to make the lens.
Then, a micro-optical sensor on the microsensor, which has a tiny lens on it, captures light from the micro sensors and sends it to the micro lens.
A lens with a tiny micro-sensor inside of it is what gives the puliwes its unique appearance.
Califf says the pulislife is already used by companies to make custom glasses for the military, but the pulios are a completely different kind of thing.
“The idea is that it is the lens of an instrument,” Califfs said.

We are trying to build a new technology that doesn’t have the problems of using glass,” he added.
