了解精密定位中的誤差源
定位設(shè)備中所出現(xiàn)的誤差可規(guī)劃為兩類：不（可預(yù)測(cè)誤差）以及不精密（隨機(jī)誤差）。了解這些誤差的源頭以及重要性能夠協(xié)助您制定一些策略以防止與糾正誤差，同時(shí)也可使人們更加信賴系統(tǒng)的性能。以下為有關(guān)用于描述定位誤差的重要規(guī)格的詳情圖1：說(shuō)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(nèi)對(duì)小距離改變的衡量。雖然分辨率在定位應(yīng)用中是個(gè)重要特點(diǎn)，但卻無(wú)法衡量度或精密度，因?yàn)榉直媛适莻€(gè)計(jì)算值。分辨率的計(jì)算是依據(jù)控制器、電機(jī)以及機(jī)械結(jié)構(gòu)組件的規(guī)格，而因?yàn)閆aber™裝置使用備有微步進(jìn)電機(jī)驅(qū)動(dòng)器的步進(jìn)電機(jī)，因

使用柱面透鏡時(shí)的注意事項(xiàng)
大多數(shù)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(jīng)過(guò)精密處理的（彎曲）光學(xué)表面。典型的柱面透鏡具有一個(gè)柱面和一個(gè)平面，增加了制造和測(cè)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(huì)進(jìn)行進(jìn)一步的處理。表面精度由表面不規(guī)則度和表面質(zhì)量決定，這兩種規(guī)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(jié)構(gòu)，因此還具有其他的規(guī)格，包括準(zhǔn)線和母線（圖1）。這些軸線用于定義平面之間的角度。這些規(guī)格要具體問(wèn)題具體分析。圖1:柱面透鏡的母線和準(zhǔn)線。以下規(guī)格需根據(jù)目標(biāo)

如何選擇正確的均勻化柱狀導(dǎo)光管
就像光纖一樣，均勻化柱狀導(dǎo)光管利用全內(nèi)反射(TIR)，將光線從導(dǎo)光管入口透射到導(dǎo)光管出口?；恼凵渎适怯绊憣?dǎo)光管臨界角的*因素，該折射率定義全內(nèi)反射發(fā)生時(shí)的接收角。導(dǎo)光管專為具備高數(shù)值孔徑、標(biāo)準(zhǔn)數(shù)值孔徑和低數(shù)值孔徑的光源設(shè)計(jì)，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(guò)使用方程式1計(jì)算得出。在使用N-BK7導(dǎo)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(huì)發(fā)生全內(nèi)反射，光線會(huì)在導(dǎo)光管透射（圖1）。由于光線以不同入射角進(jìn)入導(dǎo)光管，則導(dǎo)光

清潔光學(xué)產(chǎn)品
在購(gòu)買(mǎi)光學(xué)元件后，行之有效的保養(yǎng)可保持其質(zhì)量并延長(zhǎng)其使用的壽命。選擇合適的清潔產(chǎn)品和使用適當(dāng)?shù)姆椒ㄅc清潔元件本身同樣重要。不當(dāng)?shù)那鍧嵎椒赡軙?huì)損壞如光學(xué)透鏡，反射鏡，過(guò)濾器或光柵等使用的光學(xué)產(chǎn)品拋光的表面或?qū)I(yè)膜，降低幾乎任何應(yīng)用的性能。另外，在清潔光學(xué)產(chǎn)品時(shí)，請(qǐng)注意您的衣服和您的環(huán)境；襯衣的拉鏈、鈕扣可能劃傷您的光學(xué)產(chǎn)品，同樣骯臟或有灰塵的環(huán)境中不適合光學(xué)應(yīng)用。清潔產(chǎn)品可使用的一些清潔產(chǎn)品和清潔方法視要清洗的光學(xué)產(chǎn)品類型和護(hù)理需要性質(zhì)而定，從除塵到表面涂抹。如拾物工具、鑷子、手套、壓縮空氣、棉
