Refractive and Diffractive Microoptic Solutions

Gray Scale Technology

Gray scale technology allows for the creation of a wide variety of shapes allowing for the best optical performance achievable. Traditional binary optics rely on a "stairstep" shaped approximation of the ideal surface shape. Gray scale can actually create that ideal shape. Curves, ramps, torroids, or any other shape is possible.

Nano-Optics

The wide range of micro and nano optical applications requires optical elements with typical structure sizes beginning at several nanometers and ending in the range of millimeters. In the case of diffractive optics, it is known from the grating equation that the feature size is proportional to Lambda/NA, which implies for applications in the UV-wavelength range to typical structure lateral dimensions in a range between 1 µm down to 100 nm and below. The fabrication of products with minimum features sizes down to the sub-micron range requires high-resolution lithography techniques.
