了解精密定位中的誤差源
定位設備中所出現的誤差可規劃為兩類：不（可預測誤差）以及不精密（隨機誤差）。了解這些誤差的源頭以及重要性能夠協助您制定一些策略以防止與糾正誤差，同時也可使人們更加信賴系統的性能。以下為有關用于描述定位誤差的重要規格的詳情圖1：說明度與精密度之間的差異分辨率分辨率指的是在可要求的范圍內對小距離改變的衡量。雖然分辨率在定位應用中是個重要特點，但卻無法衡量度或精密度，因為分辨率是個計算值。分辨率的計算是依據控制器、電機以及機械結構組件的規格，而因為Zaber™裝置使用備有微步進電機驅動器的步進電機，因

高性能調整架系統
高性能調整架專為滿足要求苛刻的應用的需求而設計。借助合適的調整架和支架適配器，您可輕松地將相機、鏡頭、顯微鏡和燈管等安裝到成像系統。此外，高性能調整架還可為重載提供支撐和穩定。每個支架均有基座、垂直接桿、鎖圈和*的調整臂。支架適配器可與所有調整架兼容。推薦成像應用使用調整架系統。圖1:連接調整架和附件要將標準安裝座和?"接桿適配器連接到任意調整架：擰下光滑的黑色陽極氧化鋁旋鈕，將適配器頂部細端插入調整架上的安裝孔，然后裝上旋鈕。白色塑料鎖定臂將壓到適配器上并可用固定螺絲擰緊（圖1）。可調安裝座沒

使用柱面透鏡時的注意事項
大多數情況下，柱面透鏡由圓柱形玻璃制成，其中柱面透鏡的圓柱面是經過精密處理的（彎曲）光學表面。典型的柱面透鏡具有一個柱面和一個平面，增加了制造和測試的靈活性。與球面透鏡非常相似，圓柱面受表面精度的影響，在精拋光后會進行進一步的處理。表面精度由表面不規則度和表面質量決定，這兩種規格與球面透鏡相同。而與球面透鏡不同的是，由于柱面透鏡擁有*的幾何結構，因此還具有其他的規格，包括準線和母線（圖1）。這些軸線用于定義平面之間的角度。這些規格要具體問題具體分析。圖1:柱面透鏡的母線和準線。以下規格需根據目標

如何選擇正確的均勻化柱狀導光管
就像光纖一樣，均勻化柱狀導光管利用全內反射(TIR)，將光線從導光管入口透射到導光管出口。基片的折射率是影響導光管臨界角的*因素，該折射率定義全內反射發生時的接收角。導光管專為具備高數值孔徑、標準數值孔徑和低數值孔徑的光源設計，而如果所使用的基片相同，則接收角相同。臨界角(θc)可以通過使用方程式1計算得出。在使用N-BK7導光管的情況下，587.9nm氦D線的折射率為1.517，θc為41°。若入射角大于θc，則會發生全內反射，光線會在導光管透射（圖1）。由于光線以不同入射角進入導光管，則導光
