Designs were developed of arrays of small-diameter (2-4 mm) unity-power telescopes to be used with nonlinear optical materials in the protection of the eyes against tunable lasers. A ray-tracing program (Super-Oslo(TM)) was used to design lenslets and predict the performance of four-lens telescopes (quads). Lens types adjudged most promising were aspheres, curved graded-index (GRIM) and kinoform (diffractive) combined with spherical. Variables included lenslet diameter, f-number, quad length, and optical gain. Packing configurations utilized square, round, and hexagonal quads. Properties evaluated included resolution, field of view, aberrations, tolerances, and overall usefulness as components in compact, lightweight goggle elements. Commercial arrays of lenslets were evaluated and found unacceptable. Bi-aspheric lenslets were designed and injection-molded. Lenses from the first supplier were unacceptable, but high-quality lenses were obtained from a second source. An array of 76 lenslet elements, constructed for evaluation of visual characteristics, showed fair optical quality.
