Reflectors

The range of a prism results from, among other things, its coating and the glass geometry. A number of Original prisms from Leica Geosystems have a special coating on the reflective surfaces – the Anti-Reflex Coating, and a copper coating on the reverse side. Without these, the range of distance measuring, ATR and Powersearch would be reduced by up to 30%. The workmanship and the durability of the copper coating are decisive for a long life. The glass dimensions, the position in the holder and with it the areal orientation, are important for measuring accuracy.

核心准确性
如果未使用原始的棱镜持有人，则会发生测量错误。替代品未根据Leica Geosystems标准进行配置，并且经常在Prism，Holder和Recording Pin之间表现出位移。持有人和棱镜构成了一个单元，该单元定义了核心和重复精度。玻璃棱镜或支架上的几何形状的最小维度变化可能导致与中心轴的偏差，从而造成测量误差。

范围
The beam deviation of a prism defines the its maximum range, according to the principle "entering beam should equal the exiting beam". The smaller the beam deviation (measured in angle seconds), the greater the directly reflected signal strength to the sender optic. The returned signal quality defines the maximum range of a measurement.

Lifetime
In contrast to many conventional prisms, the reflective copper coating on the reverse side of Original prisms consists of a support coating, a vacuum-metallised copper coating, a protective coating and an overlying coat of lacquer. The special adhesive lacquer protects the underlying layers from corrosion and detachment. Working together, the copper coating and the lacquer increase the life of the prism significantly. An additional anti-reflex coating on the sensitive front surface of the prism provides a tough resistance to scratches. The production process of these coatings is so complex that only a very few manufacturers worldwide meet the requirements of Leica original prisms.

Measurement Accuracy
当使用没有反射涂层的棱镜时，测量误差经常发生，因为棱镜的前部总是直接反映了一定百分比的信号。当水分液滴积聚或棱镜变成雾时，在后侧使用棱镜而出现错误。因此，Leica Geosystems使用规定的反射涂层或获得专利的系统来预防雾化和凝结。
