高放大倍率的變焦透鏡系統，用于機器視覺
這些變焦透鏡機器適合高放大率的機器視覺和成像應用，它們能夠良好地在光學性能和大變焦范圍之間取得平衡。 我們的模塊化變焦透鏡系統包含一個0.7 - 4.5X的變焦鏡頭（6.5X變焦范圍）或一個0.58 - 7X的變焦鏡頭（12X的變焦范圍），0.50X、0.67X、1X、1.33X和2X伸縮套筒以及可選的0.25X、0.5X、0.75X、1.5X和2.0X放大透鏡轉接件。這些元件組合在一起構成6.5X透鏡系統后，放大率為0.09 - 18，放大調節范圍為6.5X，而構成12X系統后，放大率為0.07 - 28，放大調節范圍為12X。在調節放大倍率（變焦）時，只需旋轉透鏡套筒上的旋轉環即可，即便透鏡安裝在V形壓塊中亦可以調節。請注意，每次只能使用一個放大鏡頭附加透鏡。 放大率計算系統的凈放大率M（M=像尺寸/物尺寸）等于放大鏡頭附加透鏡的放大率、變焦透鏡（根據實際設置值）的放大率和伸縮套筒的放大率的乘積。例如，如果在大放大倍率7X時使用12X變焦鏡頭、2X透鏡框和一個2X伸縮套筒，大系統放大率為2×7×2=28。請參看規格標簽了解每個透鏡組合的大和小放大率。 在使用這些鏡頭時，我們也提供C-Mount轉接件（單獨出售），可以兼容我們的C-MountCCD和CMOS相機，或任何其它標準C-Mount相機。我們還提供帶一個F卡口安裝座的2X伸縮套筒。請注意，變焦透鏡必須與一個伸縮套筒一起使用（否則圖像不能被聚焦），而放大透鏡轉接件則是可選用的。另外，使用SM1A9或SM1A10轉接件時，本頁面所出售的可變焦透鏡可以與Thorlabs公司的SM1螺紋光機集成。

a、小可分辨的特征尺寸為閾值線對極限的一半[小特征尺寸=1/(3×NA)µm]
b、匹配像素尺寸指的是疊加在兩個像素上的可允許小特征尺寸[像素尺寸=1/2(特征尺寸×系統放大率)]。如果匹配像素尺寸大于相機像素尺寸，則該系統是“透鏡限制”的。如果匹配像素小于相機尺寸，則該系統是“相機限制”的。
c、請參考透鏡的變焦設置。
d、帶同軸照明端口的MVL6X3Z變焦透鏡*兼容MVL6X15L 1.5X和MV6X20L 2X放大透鏡附件。雖然MVL6X3Z可以與MVL6X025L 0.25X、MVL6X05L 0.5X和MVL6X075L 0.75X放大透鏡附件配合使用，但是會產生一些漸暈。
