The last link in a 3D presentation is 3D glasses. If the glasses are technically correct, and manufactured with reasonable quality, the spectator will better enjoy the presentation. In 1980, we recognized the need to control the quality of the glasses to protect our 3D processes. We invested heavily in special equipment and facilities and soon became the world's largest manufacturer of 3D glasses. It wasn't enough to just make them quickly and cheaply. We understood from the beginning that the technical characteristics of the filters (lenses) was crucial to satisfactory 3D. If the public rejected the presentation because of the glasses, we wouldn't stay in business long. Over the years we have continually studied filter materials (the lenses), searching for improvements in technical as well as cost aspects. Believe it or not, there is a lot more to making "simple paper 3D glasses" than meets the eye. In the case of anaglyphic glasses (cyan/red), the colors of the filters must first spectrally coordinate with the image being viewed. With television, that is the color of the TV tube phosphors. With print 3D, it is the color of the printing inks. Both have severe restrictions. We balance our filters so as to meet specific technical standards. No one in the world has better filters. The filters must also have excellent clarity, and be free of visual defects. After lenses, we consider the paper, printing inks, and glue used in the production of the glasses. Again, over the years, we have achieved an unmatched level of balance between quality and cost. In addition, we insist the component materials must satisfy all U.S. food-safe standards. Quite literally, one can eat our glasses with no concern (except for what your friends might say). Our inks and glue are totally food-safe, and we strictly use virgin, custom manufactured paper stock. To many of our clients, these are not particularly important matters. But to us, it is our business. For all of this care, we are still able to produce a product that is highly competitive. Sure, we have competition. We know who they are, and what they produce, and what they charge. Most of our clients need only compare. Then the truth will be known. We are unique in our production capacity, quality, and price combination. Nobody can approach our capacity. As a matter of fact, many of our "competition" have had their glasses at least partially produced in our facilities. Our quality control is unequaled. Perhaps cheaper glasses can be found - but not with our quantity/quality. Further, no other supplier is actually in the 3D business. We don't work out of post office boxes or a desk in someone else's office. We are REAL and are the only "one stop" source of 3D technology AND 3D glasses. We understand the various processes, and know best what technical specifications must be met. Why else would two major TV networks (ABC/NBC) choose Dimension 3 for 3D at the same time?
There are three basic types of 3D glasses: 2) POLARIZED gray polarizing lenses 3) PULFRICH one "dark", one clear lens
We have also made millions of glasses using special lens materials, including defraction ("holographic") types, and special colors. Usually our clients provide "camera ready art" for printing on their custom glasses, but our in-house art department can aid with the design of glasses using state-of-the-art computer systems. Glasses of any shape, size, color, and, well, you get the idea.
We are so confident of our product, we ask that you come to us LAST! Bring any valid written quote for glasses, and we will do everything possible to meet or beat. We cannot guarantee we will, but we have sold over 350,000,000 glasses by doing something right.
ANAGLYPH
(blue/red)
The primary consideration (as with all glasses) is filter (lens) specifications.
With anaglyph techniques, the (usually) cyan (blue/green) and red filters
must coordinate with the cyan/red of the TV image, printing inks, etc.
It is well known that the anaglyph technique is not perfect. We are constantly
researching dye technologies in an attempt to further refine existing
filters.
Technically the oldest type of 3D viewing glasses (1850's!!!), there is still science to these "simple" things.
We work closely with specialists in developing the colors for our filters. We do not use "off the shelf" materials, as they simply do not work as well. Our current filters are as near to perfection as has ever been achieved in mass production. The key to evaluating 3D filters is to look at a B&W picture. If the filters are properly balanced, the average observer will observe a B&W image. This test is subject to "eye dominance," where the image might look more red or blue, so we use technical equipment to measure this balance. The next key is "cancellation," which is the ability of the red filter to NOT see a red image, and the cyan filter to NOT see the cyan image. This is the weakest aspect of anaglyphs. In the case of TV (and projection), the red image is troublesome. In printed 3D, it's the cyan image that gives us trouble. Except under exceptional circumstances, there is always a little "leakage" where you can see a little of the red image through the red filter, and vice versa for cyan. New video programming produced in NATURAL VISION and viewed with our glasses is an entirely satisfying combination. Other filters will most probably degrade the 3D effect. We can also make glasses using filters of the red/green variety, or other special colors as required.  Our glasses have even found their way into many films and TV shows, including NBC's FRIENDS. POLARIZED
(gray lenses)
Primarily used for projection situations (theatrical 3D movies, special venue displays). These are comparatively expensive to manufacture because of two things--the lens material and the handling of same. The handling of the lens material is very difficult and time-consuming, as it has to be specially cut at an exact angle of 45 degrees, and the material is very sensitive to scratching and humidity. In 1953, polarized glasses cost 10¢ in quantities of millions. Today, over 40 years later, the cost is typically less than 25¢. What other product has held it's price as well? PULFRICH
(dark/clear)
(Pronounced "pul-firk") People look at these glasses and think something is wrong. Most feel 3D glasses should be blue/red. Others think both lenses should look alike, such as with polarized glasses. Our glasses are designed for maximum 3D effect AND viewing comfort. The technical aspects of our lenses are not only compliant to the original Pulfrich specifications, but also maintain eyestrain-free 3D. Watch out for glasses with colored lenses. The Pulfrich illusion is most effective when viewed with glasses having "one dark lens." Colored lenses alter the color perception of the picture. True Pulfrich glasses do not require "colored" lenses, therefore allowing perfect, unaltered program color. OTHER GLASSES Perhaps the most common "outside" lens material is the "holographic" variety. It creates rainbow images of bright lights, such as fireworks. The glasses are often referred to as "fireworks glasses" for this reason. We can use your supplied lens material, or provide custom colors to your specifications. Select TALK TO US on our
