CSM Series CSM2-1 CSM2-2 Lens Tube Connector Tube Adapter Threaded Connector SM2 To SM1 Assembly Tube Optics

Product information

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:

SM1  connector

CSM1-1 is a male threaded connector at both ends of SM1, used to connect two SM1 (1.035"-40) internal threaded components. It has 3.5mm at one end and 9mm at the other end, with a total length of 19.5mm. SM1 external thread is designed for sleeve and The connection between the sleeves, the connection between the sleeve and the cage plate, the connection between the sleeve and the camera, etc. Connect the SM1 internal threaded component to optimize the length and angle of the component attached to it. 9mm one end is equipped Threaded connectors, with locking rings, they make it possible to fix the attached components after the adjustment is completed. So as to limit the depth of the external thread of any SM1 threaded component. It is convenient to adjust and fix when your two components have a biased direction.

SM2 to SM1  connector

CSM2-1 is a connector consisting of one SM2 male thread and one SM1 male thread, and an SM2 locking ring attached. Used to transfer SM2 components and SM1 internal thread components. One end of SM2 has a length of 10mm, and the other end of SM1 has a length of 3.2mm, with a total length of 18mm. Used for connection between sleeve and sleeve, connection between sleeve and cage plate, connection between sleeve and camera, etc. The position and angle of attachment to other components can be optimized. The 10mm end is equipped with a threaded connector and a locking ring is attached. They make it possible to fix the attached components after adjustment. So as to limit the depth of the external thread of any SM2 threaded component, it is convenient to adjust, adapt and fix when your two components have a biased direction.

The external thread of the lens tube adapter is designed for the connection between the SM1 or SM2 internal thread components, such as the connection between the sleeve and the sleeve, the connection between the sleeve and the cage plate, the sleeve and the camera Connection etc. They make it possible to fix the attached components after adjustment. So as to limit the depth of the external thread of any SM1/SM2 threaded component, it is convenient to adjust, transfer and fix when your two components have a biased direction.

The external thread of the lens sleeve adapter is designed for connection between SM1 or SM2 internal thread components. The coupling adapter is threaded onto the lens sleeve and clamped together to allow the assembly to engage while rotating. They allow the attached components to be fixed after adjustment is completed. This limits the depth of the external thread of any SM1/SM2 threaded assembly, making it easy to adjust, transfer, and secure when your two assemblies have an offset direction.

Description:

(1) Provide 3 kinds of external thread connectors for connecting SM1/SM2 internal thread components.

CSM1-1 is a SM1 male threaded connector at both ends, used to connect two SM1 (1.035"-40) internally threaded components. It has 3.2mm at one end and 11.6mm at the other end, with a total length of 19.4mm. 9mm end with threaded connector, included Lock the ring.

CSM2-1 is a male threaded connector with one SM2 male thread and one SM1 male thread, used to transfer SM2 components and SM1 internal thread components. One end of SM2 has a length of 10mm, and the other end of SM1 has a length of 2.5mm, with a total length of 18mm. The 10mm end is equipped with a threaded connector and a locking ring is attached.

CSM2-2 is a SM2 male threaded connector at both ends, used to connect two SM2 (2.035"-40) internal threaded components. One end is 3mm long, the other end is 17.7mm long, and the total length is 23.9mm. With lock ring.

(2) The coupling adapter is screwed to the lens tube and clamped together so that the components can be joined while rotating. Used for connection between sleeve and sleeve, connection between sleeve and cage plate, connection between sleeve and camera, etc. The position and angle of attachment to other components can be optimized.

(3) Each connector comes with a locking ring, which makes it possible to fix the attached components after adjustment, thereby limiting the depth of the external thread of any SM1/SM2 threaded component. When your two components have a preferred relative orientation, it is convenient to adjust and fix.
