By utilizing LightPath's molded lens technology it is now possible to manufacture lens arrays with high precision. Unlike etched lens arrays, where there is a great deal of non-uniformity from array to array, molding will consistently produce the same structure and performance from prototype to large production builds. Consistent focal lengths and form ease the manufacturing requirement for the end user. The molding technology also allows optical designs that require greater sag (lens thickness) such as high numerical aperture collimators for laser diode arrays. Lens arrays can be produced for direct coupling (finite conjugative) or collimating applications. Pitch tolerances are typically less than one micron and lenses can also be placed with varying pitches across the array.
