How polarized3Dglasses work

Another European company, Leica has two production plants, one in Germany and another in Portugal. All of their products including their binoculars are all designed, manufactured and assembled in one of these two plants. They did have a plant in Canada for a while but the Canadian production was taken over by the plant in Portugal.

Ultimately, prices should lower as more and more top brands outsource to cheaper producing countries like China. The technologies and skills acquired due to the high standards demanded by these top brands should continue to lower production costs and hopefully improve quality. Which should be good news for us, the consumers.

Since the company first began trading in 1996, KOMZ-Baigish a Russian company specialising in binoculars, monoculars, visual tubes, endoscopes etc, have become a regional leader. Exporting to more than 20 countries, they are the most popular Russian binoculars in today’s market.

Pulsar Optics is a company formed in Belarus in 1995. Specialising in night-vision technology, pulsar is part of the same group as Yukon and Newton Sports Optics. Which has a head office in Lithuania , they have subsidiary companies in Latvia, Ukraine, China, Russia, Belarus, and Lithuania.

Most of the components used in the manufacture of binoculars are imported from the Chinese mainland. This is because labour costs and the cost of materials are cheaper in China. Many are made to high specifications, in fact that’s the point.

The Swarovski binoculars first made an appearance in 1935 and it was 14 years later that Swarovski Optik was formed. All parts of the production and manufacturing processes are completed in-house making Swarovski one of only a handful of brands that use all Austrian materials and labour.

Bushnell is an American based company but many of its products and/or components are produced and imported from other parts of the world. Including Japan and China.

You can find examples of polarised light in many places. When light is reflected off a surface at a steep angle, such as sunlight off the surface of water or an automobile windscreen, it becomes polarised. The glare from such reflections is greatly reduced by polarised lenses in sunglasses.

Since the manufacturing boom began in China in the early 1990s, nearly all of the branded binocular manufacturers have turned to China for their parts and assembly. It’s safe to say that at least 90% of all binoculars come from somewhere between 10 to 20 factories, with more than half of these situated in mainland China.

The glasses worn by the audience in modern 3D films are polarised so that each eye has a lens that is oriented 90° from the other (like figures A and B). Thus each eye sees slightly different images, which the brain interprets as 3D. The article Depth perception has more information on how we perceive 3D.

Polarised sunglasses look like regular sunglasses, but they are able to filter out the glare from automobile windscreens and the surface of water. The glasses you wear when watching a three-dimensional (3D) film work because the lens of each eye is polarised in different directions.

Steiner is an old established German optical equipment manufacturer.In the 1980s they produced binoculars for the U.S. Army (72,000 pairs) and have continued to be involved with supplying binoculars to military customers in Europe and beyond. They predominantly produce all of their own binoculars but some of their cheaper models are outsourced (we don’t know where to).

The screens of many smartphones, tablets and some computers contain polarising filters so that the light that comes out of the screen is polarised. If you look at a cell phone while wearing polarised glasses, you will notice that, as you turn your cell phone from vertical to horizontal, at some angle, the screen will appear to turn black. The polarised light from the phone is filtered out by the polarising filter of the glasses.

Headquartered in Beaverton Oregon, Leupold employs over 700 staff but does not manufacture binoculars at this site. All of their high-end models are manufactured in Japan with their more affordable models being manufactured in China.

Another European brand, Zeiss, have been producing hand made binoculars for more than 150 years and have production plants in Germany and Hungary. Whilst most production is completed in-house, they do use imported glass from a Japanese based glass manufacturer, Ohara to make prisms and lenses.

All Nikon premier binoculars are made in-house in Japan however, the compact models are usually manufactured in China. Due to the fact that entry-level and less expensive models don’t need such an intricate manufacturing process or such high quality components, they can be mass produced at much lower costs in China.

If a pair of binoculars costs below £75.00 it is most likely manufactured in China and binoculars costing up to around £150.00 will have a high proportion of optics manufactured and/or assembled in China. In many cases it is too difficult to distinguish between original Chinese brands and original equipment manufacturers.

If you have one polarising lens (such as a pair of polarised sunglasses), you can test whether another pair of lenses are polarised by looking through two lenses and rotating one. At some position in the rotation, the polarisation of the two lenses will be perpendicular, and at that point, almost no light will pass through.

The exception to this in-house policy are their Terra series binoculars. The manufacture of some of the Terra series is done in China with the pocket models produced in Japan.

In all fairness, even though the quality of Japanese and European made binoculars are the best, the Chinese have got significantly better in recent years. Probably due to the demands of top quality brands for better components from their cheaper sourced Chinese companies.

Although China is also responsible for some of the top quality optics used by the best precision optical equipment companies with famous brand names, sadly some of the not-so-good binoculars available worldwide are also made in China.

If the slit is turned so that it is perpendicular to the wave, as shown in figure B, the wave is greatly reduced. If the wave is at some other angle relative to the wave, as shown in figure C, only a portion of the wave will make it through the slit.

There appears to be only a handful of brands that do not use Chinese components. Back in the 1970s and 1980s the majority of binoculars sold worldwide were produced in either Japan or Germany.

Consider the person in these images. In the first part of the image, he is moving the ropes up and down, creating vertical waves. In the second image, he is moving the ropes from side to side, creating horizontal waves. However, light waves come out of a light source waving in all directions – horizontal, vertical and all angles in between – as shown in the third part of the image.

Pentax is a Japanese company with around 10 manufacturing sites in countries like Japan, Hong Kong, Vietnam, Taiwan and The Philippines.

The other option is the lowering of quality worldwide as all brands start to cut corners to compete with cheaper imported models. That would be a bad thing for the binocular industry and us binocular users. The way trends seem to be heading is, the top companies that keep all production and manufacture in-house, will continue to command a greater price for their superior products.

Vortex has their headquarters in Wisconsin USA and is one of the largest manufacturers of sport optical products. Most of their products are outsourced to Japan, The Philippines and China to keep production costs low. Today most of their affordable binoculars are produced and manufactured in China.

Light waves are represented in figure D. The pattern on the left represents a light wave moving in many different orientations (directions). When it has passed through the polarising filter, one specific orientation passes through easily – represented by the red line – and the other orientations are greatly reduced.

Light travels from one place to another as a wave. In some ways, it is like a wave on a lake. Light travels out in all directions from a source, much like a water wave travels away from a rock dropped into water. In a wave on a lake, the water moves up and down while the wave travels across the surface perpendicular to the motion of the water. A light wave is similar in that something is moving up and down in one direction while the light travels in a direction perpendicular to that motion.

One method of polarisation is by the use of a special polarising filter or lens. To understand how a polarising lens works, let’s go back to our rope example. If you make vertical waves on a rope that go through a vertical slit, shown as in figure A in the image below, the waves would travel through the slit easily because the orientation of the slit is the same as the orientation of the wave.

Low quality binoculars are often made in the same factories as top quality optics. The difference is the specifications set in place by the respected companies. Many others are assembled in their home country but using parts made in China.

To understand polarisation, picture a wave on a rope. If you make a series of up and down motions while holding onto a rope, a series of waves will move from your hand along the rope, transferring the motion down the rope. The rope moves up and down while the wave (and its energy) travels along the rope perpendicular to the motion of your hand. You could also move your hand side to side and create a wave that, rather than moving up and down, moves from side to side. In both of these examples, waves behave the same way – the rope moves in one direction while the wave moves down the rope. The difference is the orientation of the waves.

However with ever improving cheaper imports coming in from the far East, how long before the top brands are priced out of the market? And what happens then?

Swarovski have been producing crystal glass and high end optics for more than 125 years in Europe. More specifically their headquarters are in Absam Austria. Since it was founded in 1895, the Swarovski company has been a family business. Founded by Daniel Swarovski as a crystal cutting company using a glass cutting machine that he developed and patented in 1892. Before that all glass for binoculars was hand ground which was a slow and difficult process.
