Characteristic


▶It can be used as extension tube of CCD camera with different diameter adapter ring (C port adapter is required)

▶Easy to construct multi-component optical system

▶Using multiple snap rings to install several optical elements in the same sleeve

▶Directly compatible with 1-inch lens sleeve with various connectors

▶It can be directly installed with 25 mm optical elements and is compatible with SM1 series interfaces

▶One end of the sleeve protrudes 3mm high, and the thread C port is used for connecting the extended length



Optical commonly used thread size standard


This is the unique thread of Thorlabs in the United States, not the commonly used optical thread. SM is the code for the thread of the sewing machine in terms of thread expression, but this company in the United States uses it to connect the internal and external threads of the optical lens and the sleeve. The nature of the thread is UNS, and the United States has a special thread with a tolerance accuracy of 2A / 2B. The special place of this thread is 40 teeth per inch regardless of the diameter. The specific dimensions are as follows:


 

 

 

Lens tubes are very suitable for building compact optical cage systems. The sleeve can be used to install one or more optical components. With our snap ring, you can easily set the depth of the snap ring to separate and fix the optical components. These stackable lens tubes are compatible with SM1 (1.035"-40) threaded components. Lens tubes with a height of 8mm or more come with a retaining ring (CSA-04/CSA-05 does not ship with a retaining ring, and is mainly used as an extension tube). You can also purchase additional snap rings to build the system.



 

 

One end of the sleeve has an SM1 thread protruding with a height of 3mm. In addition to stacking compatible SM 1 threaded components, it is also compatible with a C-mount adapter, which can be used to transfer a CCD camera interface.

 

Application scenario display

We supply a wide range of optics to create an easy-to-build experimental platform in an optical system.

 

Why do we choose Alcoa 7075 aluminum alloy?

Lighter, stronger, more durable, and superior thermal stability

Because 7075 has better mechanical properties, and has good ductility, high strength, toughness and good fatigue resistance. Under the same material, the 7075 is 64% higher and 58% higher than the 6061, and the tensile strength and strength are 85% and 82% higher, respectively.

Ingenuity, excellence

In the eyes of the refined craftsman, the micron-level gap of the precision thread pair will lead to deviations in the optical test results. Only after dozens of manual grinding and inspections, we are careful and ingenious, only to create a more stable and reliable optical machine product. To help your experiment, teaching and research and development projects go smoothly.
