LentiClear Lenticular Lens, Inc. (dba) Jacobsen Lenticular Tool & Cylinder Engraving Technologies Company ("JacoTech") is at the forefront of advanced complex machining techniques and provides the global plastics-processing sector with scientific solutions, from research and development to full turn-key production of optically-based cylindrical polymer/plastic roll and sheet materials processing, including the in-house manufacturing of micro-structured optical-quality roll-surface mold component parts used for the managed control of light. The focus of JacoTech’s custom optical micro-machining engraving business is ultra-precision, computer numerical control (CNC) diamond turning, milling, drilling, fly-cutting and laser ablation processing of cylinders, drums, rolls, mandrels and flat plate molds used to extrude/emboss/cast or calendar plastic and polymer based sheet and roll films and structured light shaped materials. These optical-grade engraved cylinder/flat plate processing molds contain simple to complex geometrical patterns designed to perform a number of complicated light management control functions. By using its custom-designed, precision large-scaled machining centers sized at 2 and 3 meters wide, JacoTech engraves complex circumferential, circular, and angular, plus other custom hybrid shaped optical patterns into machinable materials such as copper, aluminum, electrolytic and electroless nickel alloys, beryllium copper, brass, gold, and alloys. Diamond mechanically and laser machined geometries can include plano, spherical, parabolic, general aspheric, toroidal, hyperbolic, elliptical and other exotic cylindrical shapes, including vertical, horizontal, angular and circular patterns or custom hybrid combinations of various structured shapes. JacoTech also produces cylindrical and flat plate optical molds for (non-imaging) applications such as OLED displays, 3-D & 4-D display monitors, image projection, retroreflective prismatic road/traffic control signs, and custom lens systems for structured lighting devices used with automotive and aerospace to outer space lenses. Fabrication of these in-line direct-machined complex optical molds is intricate but they can be manufactured quickly, usually within 4/5 weeks or less.
