The Device that Spurred the Creation of Optical Systems
Thursday, August 20, 2015
The team at Greenlight Optics
designs, manufactures, and tests prototypes of multiple optical products on a
daily basis. But this team wouldn’t be able to regularly work on these
optics-related products without one of the pioneers that led human beings to
where we are today. While this pioneer isn’t necessarily a person, it did help stir up ideas to create more optical systems,
instruments, and products.
Imagine the only part of the night
sky you could see was the part you saw when you simply looked up. Besides many
people needing some form of corrective lenses, what can you see? Not much other
than the white light from a few stars (in comparison to the thousands of millions
astronomers have discovered), right? What if observers of space had never discovered the other planets in our
solar system, or even that the earth revolves around the sun — and not the
other way around? They wouldn’t have been able to without this optical
instrument, the telescope.
Coming in a wide range of sizes
that can have different magnifying capabilities, the telescope has been around
for a great deal of time. Well, its earliest known working form has been, anyway. Its first appearance dates
back to 1608, but there is still a dispute of which man among three rightfully
invented the optical instrument. That, however, is a subject for a rainy day.
What is
important to the Greenlight Optics team is that optical systems have
been improved, and the technology advanced to pave the way for the devices
people use today.
Though the first known working telescope dates back the 17th century, the manufacturing of
lenses can be dated back to the 10th century. But, it would take just a bit longer to have convex and concave
lenses work together in an optical system that would aid humans in seeing
faraway, extremely faraway.
This telescope that the three
inventors disputed over who was the first and true inventor, was specifically a
refracting telescope, a telescope that uses lenses to magnify the image a
person is looking at. After this 17th century optics invention had been
patented, other optical telescopes have been invented, and thus, improved upon.
There are also reflecting telescopes, which are telescopes that use mirrors for
magnification, and catadioptric telescopes. This last type of optical telescope
is an optical telescope that combines the best of both worlds the ideas
of both reflecting and refracting telescopes: a catadioptric telescope uses both lenses and mirrors to
form an image. They are, though, specifically shaped lenses and mirrors for
this purpose.
Though it’s still unclear which of
the three inventors first created this optics device, other scientists,
engineers, astronomers and the like would come forth in the years following to
help make this latest optical instrument a better gadget — two of whom happen
to be the subject of upcoming blog posts.
