It is a known fact in the lenticular extruding industry today, that the current traditional method of supplying lenticular extruding cylinders consists of applying a soft copper base plating onto a steel green base cylinder surface, which is then diamond turned and engraved. After the lenticular engraving, a post chrome thin-flash plating is applied on top of the copper engraved plating, only to help protect the soft copper finish underneath from oxidation and staining. The post chrome plating does very little to protect the copper lenticules from damage or wear while extruding.

NOTE: The following schematics and explanations illustrate the numerous advantages of the new patented and patent pending LentiClear aspheric/elliptical lenticular lens, versus the typical industry standard cylindrical lenticular lens that uses prior art and much older technology.
As you can see from the above illustration, the industry standard lenticular lens uses a cylindrical shape. (Note: The print material is located to the left of the lens and the view is located to the right. For best performance, all of the light rays exiting the lens should be parallel or collimated). Due to a spherical aberration, only the rays in the central portion of the lens exit in this desired manner, while the rays farther from the center begin to significantly change from the desired direction. As the light rays reach the outer portion, the light can be seen to internally reflect, which ultimately returns the highly defocused light to the print material. This reduces the overall light output, brightness and contrast of the image when viewed through the lenticular material.
The new LentiClear lens (see above illustration) overcomes the shortcomings of the standard lenticular lens by utilizing an optimized aspheric/elliptical shaped lens that effectively collimates the light from the printed material. The light is well collimated, no light is internally reflected, and the full aperture of the lens is used. The enhancement in contrast, clarity, and brightness afforded by the new LentiClear® lens brings sensational improvements and added opportunities to the entire lenticular industry.
Now, compare images projected from several points on the printed material by the industry standard cylindrical lenticular lens versus the new LentiClear® aspheric/elliptical lenticular lens. The excellent performance of the LentiClear® lens clearly demonstrates that the light from the points is essentially collimated and forms well-defined and separated beams. On the other hand, the performance of the industry standard cylindrical lenticular lens illustrates that light is poorly collimated and the light from different points on the printed material is intermingled. This causes the projected images to have dramatically less clarity and contrast than images produced using the new LentiClear® high performance lenticular lens.
The new LentiClear® lenticular lenses also provides a much wider field-of-viewing angle, as well as providing brighter, clearer and better contrast images than the typical cylindrical lenticular lenses.

Prismatic V-Grooved Patterned Engraved Casting Cylinder. The photo shown is one of our diamond turning machining centers, taken with a camera flash which illustrates its brilliance in reflective optical properties. The optical pattern features a shallow 0.0005" (5/10 thousandths of an inch) into a diamond turned mirror-finished optical grade copper plated roll. The cylinder will yield high quality uv resin casted high reflectivity thin-lens film used for integration into cell phone and display monitor screens. The technology can be used for other light control management applications.
75 lpi Lenticular Production Cylinder. Here's an actual 75 lpi lenticular production cylinder engraving close up image of JacoTech's ultra-precision 360 degree circumference step and repeat diamond turned engraving. The secret to an essentially perfect defect free lenticular lens sheet is first having a properly manufactured engraving. The mold tolerances must be consistent and repeatable over the entire roll face. Assuming a roll face width of 66" x 75 lines per inch = 4,950 lenticules, during engraving production the diamond tool travels 475 miles, if measured in driving distances.
JacoTech provides new Custom Light Pipes for plastic extrusion processing of thin-gauge volumetric lens sheet & roll manufacturing. These transparent polymeric lens/foils are used as light guides to direct light and scatter rays as desired for end lighting products. The optically functionalized light pipe lenses structure are typically made of acrylic and PMMA resins by large area hot-embossing. JacoTech's new offering allows the extrusion process to fabricate the light pipes in thin-gauge to save money and increase production, thus lowering overall product costs of lighting companies.
