OAP提供无障碍孔径的优点,使系统设计中的焦平面可以访问。这确保轴上的纯衍射图案,没有由“蜘蛛”引起的尖峰或其他障碍物。如果正在进行MTF和类似的测量,这一点尤为重要。离轴抛物面镜由于其完全消色差特性而特别适用于宽带和多波长应用。
应用包括:
•准直仪
•扩束器
FLIR测试
•大功率激光束聚焦
•目标投影
MTF参考表面
•机读旅行证件测试系统
•光谱镜

说明: off-axis paraboloids

可根据要求引用较小的机械和光学公差。镜子直径为125mm或更大的通常用后面“平行”制成前面如上图所示。如果需要可以将楔形物施加到背面,使得它垂直于光轴。 我们还将在镜子空白中引用各种定制的凹口,槽,单位或其他加工形状。我们强烈建议所有镜子按照安装方式进行订购 - 根据要求详细说明。然后,您将有信心将镜子保持在无应力状态。涂层和安装后可提供中间照相。
