We introduce a new type of drop-in technique used to passively and accurately center lenses in optical mounts. This lens mounting method is called edge contact mounting and uses the edge at the intersection of the cylindrical and optical surface of the lens as the mounting interface. By providing a spherical mounting seat for the lens on a simple standard threaded ring, it is possible to center accurately lenses of different geometries, diameters, and radius of curvatures. The method allows relaxation of some manufacturing tolerances compared with rim contact drop-in and is not subject to a minimum clamping angle as for the surface contact mounting. This innovative lens mounting method allows extension of the centering accuracy offered by passive lens centering methods to a next level without compromise on cost and complexity.

使用边缘接触安装实现高精度镜头对中

我们介绍了一种新型的插入式技术，可用于无源且准确地将光学装置中的镜头居中。这种透镜安装方法称为边缘接触安装，并且使用透镜的圆柱面和光学表面相交处的边缘作为安装接口。通过在简单的标准螺纹环上为镜头提供球形安装座，可以精确地将不同几何形状，直径和曲率半径的镜头居中。与轮辋接触件插入相比，该方法允许松弛一些制造公差，并且不像表面接触件安装那样受到最小夹紧角的限制。这种创新的镜头安装方法可以将被动式镜头对中方法所提供的对中精度扩展到一个新的水平，而不会影响成本和复杂性。
