    • A light source module is disclosed. The light source module includes an emitter having a light emitting surface, a solid integrating optic aligned to accept light emitted from the emitter at an entrance face and deliver light to an exit face, and a lens aligned to receive light from the exit face. The lens has a substantially hemispherical portion having a radius of curvature and the exit face of the solid integrating optic has an exit face diagonal. The ratio of the radius of curvature to the exit face diagonal is greater than 0.7. The solid integrating optic and the lens each have an index of refraction, and the ratio of the lens index of refraction to the solid integrating optic index of refraction is greater than unity.

    • A method for sensing and analyzing topographic properties of an aspheric test element is disclosed. The principle of the measurement technique is to immerse the element under test into a container filled with liquid crystal. A polarized plane wave passes through front and back precisely processed glass plates of the container sandwiched between a polarizer and an analyzer. The two side plates are not transited by the plane wave of light but are deposited with conductive layers in order to generate an electrical field between them. This DC (direct current) external electrical field is supplied to help to align the molecular direction of the liquid crystal. In a thus-induced desired configuration, the molecular direction of liquid crystal is aligned to be perpendicular to the incident plane wave front. As the plane light wave propagates through the liquid crystal in the container, it will be divided into ordinary and extraordinary beams. These two beams will create interference behind the analyzer. In the presence of the aspheric optical element under test, which is not a uniaxial crystal, a compensatory interferogram will be formed. Analysis of the interferogram will allow the user to determine the topographic surface profile of the aspheric element under test.
    • 公开了一种用于感测和分析非球面测试元件的地形特性的方法。 测量技术的原理是将被测元件浸入装有液晶的容器中。 极化平面波通过夹在偏振器和分析器之间的容器的前后精确加工的玻璃板。 两个侧板不被光的平面波转移,而是沉积有导电层,以便在它们之间产生电场。 该DC(直流)外部电场被提供以帮助对准液晶的分子方向。 在如此诱导的期望构型中,液晶的分子方向与入射平面波前垂直。 当平面光波通过容器中的液晶传播时,它将被分为普通和非凡光束。 这两个光束将在分析仪后面产生干扰。 在不是单轴晶体的非球面光学元件的存在下,将形成补偿干涉图。 干涉图的分析将允许用户确定被测非球面元件的地形表面轮廓。
