Amin和Amax是使用锁环时其它透镜套管到透镜安装单元后部的最小和最大距离。

特性

  • 延长的外螺纹，可用于调节已安装光学元件的位置
  • 可选调节范围：0.31英寸(7.9 mm)或0.81英寸(20.6 mm)
  • 夹持Ø1/2英寸(Ø12.7 mm)光学元件
  • 光学元件的最大厚度为0.43英寸(11 mm)
  • 包含一个卡环和锁环
  • 真空兼容版本的可调范围是0.31英寸(7.9 mm)

这些长度可调节的SM05(0.535"-40)透镜套管允许将Ø1/2英寸的光学元件沿着透镜套管系统的光轴精确定位。操作时，利用附带的包括SM05RR在内的卡环将光学元件安装在长度可调节的透镜套管中。然后将长度可调节的透镜套管旋入兼容的SM05螺纹透镜套管或透镜安装座上，直至光学元件抵达所需的位置。此时，可利用附带的锁定环将光学元件固定就位。这些可旋转调节长度的透镜套管是对透镜套管系统中第一个和最后一个透镜进行微调的理想解决方案。尽管透镜套管可连接在长度可调节的透镜套管前面，只有当光学元件的位置固定以后才可以连接，因为如果光学元件的位置改变，就需要旋转和平移该透镜套管。

SM05V05和SM05V10可调透镜套管包含一个SM05RR卡环。对于手够不到锁定环的应用，我们提供SM05NT1开槽锁定环和SPW502扳手。该锁定环包含的槽口用于扳手的3/4英寸一端。

SM05V05V可调透镜套管是SM05V05透镜套管的真空兼容版本，但是额外具有沿螺纹直达两端的通风槽。在抽真空时，这些通道可将滞留在安装光学元件之间的空气排出。这种透镜套管包含一个SM05RRV卡环和SM05NT1V锁环。所有组件使用6061-T6铝制造，所有这种可调透镜套管兼容最低10-6 Torr的真空。

螺纹规格

以下内容为螺纹概述。更多有关规格和尺寸的详细信息，请查看机械手册(Machinery's Handbook)，此手册可在书店购买。

螺纹特性
螺纹具有三个重复的特性：牙顶(crest)、牙侧(flank)和牙底(root)，见右图。通过牙顶或牙底中心绘制垂直线时，除特殊情况外，螺纹具有以相等角度倾斜的对称侧面。相邻螺纹上对应点之间的距离称为螺纹的螺距(pitch)。牙侧角(flank angle)定义为牙侧与从螺丝轴绘制的垂直射线所成的角度。除非另有说明，一般螺纹的牙侧角为30°，因此牙侧之间的总角度为60°。以上每个特性都显示在右侧图中。

大径(major diameter)取自螺纹的牙顶，而小径(minor diameter)取自螺纹的牙底。对于大多数螺丝，牙顶和牙底并非为尖点，因此大径和小径的定义包含了牙顶和牙底截断值。中径(pitch diameter)的端点大约处于大径和小径端点的中间。

螺纹牙型
螺纹牙型(thread form)表示一组规则，用于定义特性之间的比例。常见的螺纹牙型包括在美国使用并以英制单位测量的统一螺纹牙型，以及在世界许多地方使用并以国际单位制测量的ISO公制螺纹牙型。由定义平牙底轮廓的UN或定义圆形牙底轮廓的UNR指定的统一螺纹标准中有许多螺纹牙型。这些牙型可以通过附加更多字母来进一步描述。例如，具有平牙底轮廓的极细螺纹被指定为UNEF。那些未被统一螺纹系统标准化的牙型被指定为UNS。

螺纹系列
大多数螺丝可通过它们的螺纹系列来识别。螺纹系列由螺纹的大径和密度表示。统一螺纹以每英寸的螺纹数来指定密度，而公制螺纹由螺距指定。例如，在统一命名法中，1/4"-20带帽螺丝的螺纹直径为1/4英寸，螺距为每英寸20个螺纹(TPI)。在公制命名法中，M4 x 0.7带帽螺丝的螺纹直径为4 mm，螺距为每0.7 mm 1个螺纹。术语M4 x 0.7通常简称为M4。

  • 等级越高，公差越宽松。带下划线的等级用于螺纹啮合的正常长度。

螺纹等级
螺纹系列的公差由螺纹等级给出。统一螺纹等级为由1到3的数字开始的字母数字标识符，其中1是最宽松的公差，3是最严格的公差，A表示外螺纹而B表示内螺纹。

公制螺纹具有一种稍复杂的公差方法，它使用由数字3到9表示的公差等级；以及由字母e到h表示的公差位置。等级提供了公差本身的度量：数字越小，公差越严格。位置表示公差与中径的距离。大写位置字母表示内螺纹，小写位置字母表示外螺纹。

机械手册(Machinery's Handbook, 29th Edition, p. 1885)中说：“为了指定公差等级，首先需显示中径的等级和位置，然后是外螺纹的大径或内螺纹的小径，即4g6g表示外螺纹，5H6H表示内螺纹。如果等级和位置两个符号相同，则不必重复使用符号，因此单独的4g代表4g4g，单独的5H代表5H5H。"

Thorlabs的SM系列螺纹
我们的SM螺纹规格用于我们的透镜套筒和笼式系统组件，如下所示，因此您可以加工匹配组件以满足您的应用。大多数SM系列螺纹采用非标准统一螺纹牙型，由字母UNS表示，牙侧角为30°，螺纹等级为2A和2B。我们的SM30系列螺纹是个例外，它是一种公制螺纹牙型，牙侧角为30°，公差为6H/6g。我们还提供带C-Mount和RMS螺纹的产品，这些螺纹的规格请参考下表。请注意，其他制造商可能具有不同的C-Mount和RMS螺纹公差。如需此处未列出的螺纹规格，请联系技术支持techsupport-cn@thorlabs.com。

Does the adjustable lens tube allow rotation of the optic independent of translation? The 2D hatched section view looks like it might, but the 3D CAD model does not, showing it as a single body.

Thank you for your feedback. Besides the included locking nut and retaining ring, the SM05V05 is a single body. The tube itself will not rotate the optic without translation.

Hello, the locking ring SM05NT does not fit in between 16 mm cage construction rods (it cannot be rotated then - locked/unlocked). We bough one to tune the position of the lens to collimate the fiber within cage assembly. Could you decrease its diameter?
YLohia  (posted 2018-07-03 10:14:36.0)
Hello, thank you for your feedback. I have posted this idea in our internal engineering forum. Reducing the diameter would indeed make this compatible with the 16mm cage system.

How can I couple this SM05V10 to a c-female thread? In other words, I would like a c-mount coupler to my 1/2'' lens. What can you offer? Best Regards, César

Thank you for contacting Thorlabs. We have a C-mount to SM05 adapter part number SM05A1 which can adapt the SM05V10 to a c-mount threaded camera using another SM05 lens tube.
