Criterion This is where you specify what Zemax looks at when it does the tolerancing. This difference can be calculated as either a Root-Sum-Square (RSS) change or a Linear Change. A fabrication technician can then use this tolerancing metric with appropriate metrology data to determine if the device will yield acceptable performance. Zemax perturbs each of the specified degrees of freedom in the minimum and maximum direction and measures the change in the criterion you set (discussed below). In each case, a metric can be produced showing the ability of the design to meet performance goals within the specified tolerances. For the second design, fiber-coupling efficiency is tabulated for a biconic lens. Since the fibers are used without the couplers, the intensity of the light received as well as the measurement phase is relatively susceptible to the changes of fibers’ position and orientation during coupling. In the first design, the radius of curvature and conic constant are varied for an aspheric lens, and the change in the spot size is determined. The optical components in the encoder head are bonded together and the core diameter of the multimode fibers employed is 200 m. Two designs are presented with the tolerance analysis results. The goal of the tolerance analysis is to assess the sensitivity of a microlens design to changes in the shape of the lens surface with regard to specific optical performance criteria related to the intended application. R 1 R 2 R, and the distance between the mirrors is equal to the mirror radius, i.e. For the special case when the two mirrors have the same radius, i.e. Axes of channels are predefined or may change. Parameters able to be measured by available metrology tools are assigned tolerances. It can be seen from Equations (1) and (2) that the position of higher order transverse modes strongly depends on mirror spacing, L, and the radii of curvature of the mirrors, R 1,2. radiation of sources, structures of optical elements and detectors.

A method for tolerancing microlenses to ensure operating performance using the optical design code ZEMAX (R) is presented. This paper demonstrates a new tolerancing technique that allows the prediction of microlens optical performance based on metrology measurements taken during the fabrication process.
