Opera Glasses " Much More Than Just Small Binoculars
If it wasn't for the Dutch optician Hans Lipperhey, we might not have had either binoculars or opera glasses today. He first started manufacturing simple binoculars in 1608. These were not much more than two telescopes connected by a central bridge, but they led to many further modifications and improvements. His early binoculars had a magnification capability of x3. Within less than a year the Italian mathematician and inventor Galileo Galilee made another drastic stride forward by increasing the magnification ability of telescopes to x30.
Binoculars of the time had one major disadvantage: Despite offering a much wider field of view than a telescope, they made use of convex lenses - which resulted in the image being inverted! It wasn't before more than 100 years later that Anton Schyrle for the first time manufactured binoculars with an extra lens that re-inverted the image. And it took another--1 years before John Dollond of England solved another big problem that binoculars had - color distortion. He started using achromatic lenses (color free lenses) and thereby solved this problem permanently.
The next step forward was made when an Italian gunnery officer by the name of Ignazio Porro developed prismatic binoculars during the '50s. These offered an even wider field of vision than earlier binoculars and also a drastically improved magnification ability.
We don't find any mention of opera glasses in the printed media before the 1730 - in London. These rather primitive opera glasses were not binoculars - they were mini-sized Galilean telescopes. People used them for decorative purposes as much as to watch opera. The bodies were mostly highly decorated with numerous gems, enamel, mother of pearl and ivory.
We find references to binocular opera glasses for the first time in Vienna during 23. They were still really not much more than two tiny telescopes connected by a bridge. You had to focus the telescopes individually by expanding the tubes.
They proved to be very popular, however, and quickly became items of high fashion. The designs were so elaborate that one often would find both a painter and a goldsmith working on the end product. They were used as much to impress people as to watch opera - not to mention scrutinizing other opera goers to see if their opera glasses were perhaps more fashionable than yours!
The design was further improved substantially when it became possible to adjust both lenses at the same time using a small wheel in the center. This made opera glasses even more popular and soon everyone who was anyone had to have one. They were highly regarded as gifts - as one can clearly see when you study the inscriptions on many of these glasses dating back to the 17th century.
Nowadays there is a wide array of opera glasses available. You can get them in virtually any color you want. They come in many different styles and materials. Strangely enough, monoculars are still popular, as are opera glasses with handles or reading lights. You even get them fitted with a jealousy glass - so you can watch another person in the audience without being seen! - 18780
