Imaging technologies spur 3D viewer design upgrades

Suppliers of 3D viewers are enhancing models to cater to the growing number of stereoscopic products.

Aiming to keep up with the latest video and print entertainment technology, China suppliers of 3D viewers are creating models suited for different media. Among the variants offered are anaglyph glasses, linear polarized glasses and circular polarized glasses.

Kingwell's paper 3D viewers adopt 0.2mm thick PET lenses.

The products are designed to adjust a user’s vision when looking at stereoscopic images. A 3D figure generally consists of two pictures superimposed onto the same area via two opposing polarizing filters. The latter helps separate and define light waves into particular beams.

The 3D viewers, in turn, select and block the kind of light coming in through each eye. The right will notice a slightly altered perspective from the left. When combined, the resulting image provides the illusion of depth.

The simplest manner of achieving this effect is through complementary-colored lenses. Anaglyph glasses, in particular, are red on one side and either green or cyan on the other. Based on the tristimulus theory, wherein humans detect light in three basic shades, the red lens is designed to accept only reds. Cyan and green counterparts allow just blues and greens to enter.

Anaglyph variants, however, permit a limited range of hues and are generally low-end, promotional items for one-time use. Red-and-cyan viewers can be utilized for 3D-ready movies, TV shows, games, pictures, books and magazines. Those with green filters are suited for watching fireworks.

In contrast to complementary-toned releases, polarized glasses enable wearers to see in full color, making them popular for 3D films. The lenses may be either linear or circular, depending on the orientation of the image projector.

The first deals with light waves traveling in straight beams. It interprets stereoscopic figures shown through orthogonal polarizing filters that cast pictures at a 45 to 135-degree angle.

The linear polarized glasses are also fitted with different filters per lens. This allows each side to absorb only the corresponding polarized light and block the rest. But because the products rely on linear vision, users must keep their heads at a level position. Tilting may cause the images to bleed and even lead to some discomfort.

Circular polarized glasses, meanwhile, do not limit movement and provide a wider viewing angle. The models filter coil-shaped light waves by identifying their handedness or turning direction. To illustrate, polarized light traveling counterclockwise can only pass through left-handed analyzers.

Such stereoscopic glasses, however, are more complex to produce and are therefore costlier. Releases require quarter-wave retardation plates to convert straight beams into spirals. But despite the higher expense, output for these pairs is larger given the growing popularity of 3D movies.

Products & prices

China’s 3D viewer selection is mainly differentiated by the materials adopted, particularly for the frames and the lenses. The first component accounts for the bulk of unit cost.

Paper frames contribute about 50 percent to product expenses. A popular choice is 180 to 250g cardboard that may be printed with colorful patterns. Models can come in two-leg, handheld or bind-in styles. Although polarized glasses are offered, most releases are anaglyph kinds for promotional or single use.

Plastic frames comprise 30 to 50 percent of outlay per pair. The glasses are made of ABS, PC, acrylic or acetate, with the first dominating yield because of lower costs. The releases are available in two-leg, clip-on and wraparound designs.

In terms of lenses, the selection is available in PET, TAC and acrylic. PET is the most common choice as it is the least expensive. Those used in anaglyph viewers are typically 0.15 to 0.2mm thick. Finished items are between $0.03 and $0.06.

Linear polarized glasses with ABS frames often have 0.23mm PET lenses, while circular polarized glasses utilize 0.3mm filters in the same plastic. They are priced at $0.20 to $0.45 and $0.35 to $0.65, respectively.

TAC lenses are more commonly employed in polarized glasses. Pairs that adopt 0.7mm thick versions usually exceed $2. Acrylic lenses in similar dimensions are available as well.

Adding treatments such as anti-UV, -glare, -dust and -scratch coatings raises quotes.
