这是一款在标准光学窗口基础上，集成了长方形、圆角、台阶三种设计特征的特制光学元件。它选用 K9光学玻璃作为基底，因兼具优异的光学性能和针对特定应用的机械结构优化，非常适用于对安装精度和密封性有较高要求的场合。

圆角设计：窗口的四个角被处理为圆角。这不仅是出于美观， 重要的是消除了直角处的应力集中，能显著降低窗口在安装或受压时（尤其适用于高压或真空环境）的破裂风险。同时，圆角也 便于与O型密封圈配合，提升密封性，并能避免尖锐边缘划伤安装夹具或密封材料。

台阶结构：在窗口边缘加工出一个或多个台阶。这种结构主要为满足 的机械定位和安装需求而设计。台阶可以充当限位和固定的作用，有助于在激光系统、光学传感器或真空系统中实现 的安装重复性和密封效果。台阶面通常只做精磨处理，而通光面则进行精密抛光。
