Currently most of people not especially knowledgeable in the matter of optics think that Porro prisms binoculars are outdated and roof prisms models are modern. It would be difficult to agree with such a statement because first roof models were launched almost precisely at the same time as Porro instruments; we owe former of them to the German Moritz Hensoldt & Sons company which already in 1905 showed first models of that type calling them Dialyt.
The golden age of Porro binoculars lasted several dozen years and started right after the World War II. Among many models the 8x30 devices were undoubtedly the most popular ones. Zeiss factories, moved to Oberkochen, started their production from that model exactly; Leica were still manufacturing the Binuxit model, launched before the war, and Swarovski showed their Habicht 8x30W on the market at that time as well.
An optical system of almost every contemporary pair of binoculars consists of three parts: an objective lens which gathers the light, a prism assembly, inverting the image and an eyepiece, decisive when it comes to a magnification ratio and a field of view.
It’s difficult to say when exactly the first pair of binoculars was created. An idea to put two telescopes together was perhaps not exactly difficult to come with; it most probably occurred not later than at the beginning of 17th century, with the usage of the first refractors.
We haven’t published any spotting scopes tests on the Optyczne.pl/Allbinos.com site yet although we have been thinking about doing so several times. Unfortunately conducting such tests is not an easy task – in fact it is far more complex than testing binoculars.
The Sky-Watcher BKP 150750EQ3-2. Not the most romantic name, to tell you the truth but if you are one of these people who feel a bit lost amid the jungle of telescope offers and different astronomical- observatory optics, this piece of equipment should definitely interest you.
We are continuing the history of Polish Optical Industries. Let’s just remind here that the first part of the article encompassed the beginning and a very quick development which was stopped all of a sudden by the onset of WWII.
We’ve already featured series of articles describing the history of such companies as Canon, Leica, Nikon, Olympus and Sony (available only in Polish on Optyczne.pl). Many people have been asking us afterwards to publish next parts, with the history of others foreign optics producers.
Adrian Warwas - Head of Export Non Hunting Channels Question: Let\'s start with some history. When and how did the Steiner binoculars\' history start? When were the first models launched and what were their parameters? Answer: The pioneer Karl Steiner established the STEINER-Optik GmbH STEINER 1947 in Bayreuth.
While discussing our tests we’ve met several times with controversial statements about the colour rendering different binoculars or lenses offer. More particularly these doubts concerned why we assess the white rendering of older Russian, Polish, Romanian and Czech products so low, including also the binoculars which were produced by Zeiss in Jena.
Left: Arkadiusz Olech (Editor-in-chief: Allbinos.com/Optyczne.pl). Right: Anthony Proper (Alpen Optics Vice President of Sales) Question: How the history of Alpen Optics binoculars has begun? When the first Alpen binoculars have appeared on the market and what parameters they had? Answer: Alpen Optics was established in December of 1996.
Binoculars tests, published on Optyczne.pl/Allbinos.com are conducted by a group of great optics enthusiasts with a lot of experience under their belts. We’ve handled about 500 pairs of binoculars so far plus several dozen of spotting scopes, telescopes, many eyepieces and plenty of other optical devices as well.
Apparently binoculars seems to be a poor optical instrument. Any average astronomical telescope can gain higher magnification and thanks to a big lens is able to gather more light. Fortunately, considering binoculars, magnification is not the most important thing.
A binoculars consist of three main optical parts: front lenses, prisms and eyepieces (oculars). Lenses conduce to gather as much light as possible. Eyepieces are essential to magnify the image and direct it into our eyes as a parallel light beam.
Most trappers asked for the typical and classic binoculars destined for night-hunting will point at model with 8x56 lens so equipment with 56 mm objective diameter and 8x magnification. Others will probably add 7x50 and 9x63 and that’s the end of suggestions.
