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.

Centring Accuracy
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
棱镜的光束偏差定义了其最大范围，根据“进入光束应等于出口光束”的原理。梁偏差越小（以角度为单位测量），直接反射的信号强度越大。返回的信号质量定义了测量的最大范围。

寿命
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.

测量精度
Measurement errors occur frequently at close ranges when prisms without anti-reflex coating are used, as the front of a prism always directly reflects a certain percentage of a signal. Errors occur in the use of prisms without copper coating on the back side when moisture droplets accumulate or the prism becomes foggy. Leica Geosystems therefore uses either the stated reflective coating or a patented system for the prevention of fogging and condensation.
