为了寻找最佳材料，隐形眼镜的研发团队需要对多种柔性聚合物材料进行测量。被测材料需要在测量时，浸入盐水中。由于隐形眼镜极容易被测量所影响，所以必须采用非接触式测量方法。由于众多光学测量方法无法测量浸入液体中的塑料结构，传统的穿透类激光传感器也无法准确区分样本和周围的液体，视觉相机又非常依赖于周边的光线条件。米铱公司提供的光幕千分尺则非常适合本案例。

In their quest for better materials, Research and Development teams at contact lens manufacturers have a need to conduct  various material tests on clear, flexible polymer samples. The material samples must be submerged during testing in a saline solution for hydration, as they have completely different properties in their dry state as in their hydrated state. The challenge is to find a way to measure dimensional changes in the samples while stretched, heated, etc. while inside small hydration enclosures. Since contact sensors could easily influence the measurements, a non-contact method is preferable. Also, since the plastic is almost invisible when submerged, most optical measurement technologies would fail in this application.
