CSA2 Series CSA2-1 Ø2" Lens Tube Stacked Tube SM2 Threaded Shading Tube Cage Coaxial Lens Tube Frame Optical Experiment

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:

Parameter: 

(Multiple specifications are available)

Characteristic:

►SM2 (2.035"-40) threaded hole for mounting Ø2" (Ø50.8 mm) optical components;

►The protruding thread is 3.0mm, with a stacked design;

►The stackable design can build a multi-element optical system;

►Compatible with our 60mm cage assembly system;

►It can be used as lens tube shading element to shield the light path and provide opaque solutions;

Description:

(1) Build an optical cage experiment platform.

(2) Drawing display.

(3) The lens tube is very suitable for building compact optical components. The Ø2" lens tube is used to install one or more optical components (shown in the schematic diagram of the beam expander). The optical components are separated and fixed by a snap ring, which is positioned at the required depth in the lens tube (1 snap ring is included, if you need more snap rings, you need to purchase additional snap rings separately).

(4) The lens tubes are externally SM2 (2.035"-40) threaded. These Ø2" stacked lens tubes can quickly and easily build compact optical components. They have a stackable design and can directly join all SM2 (2.035"- 40) Threaded components help to flexibly build complex optomechanical components.

(5) Compatible with our 60mm cage assembly system; in the cage system, it can be used as a lens tube shading element to shield the light path and provide an opaque solution;
