Pre-aligned optical axes
Four rods define the axis, so every element threaded onto them starts square and centred.

SM1 Lens Tube
Zolix SM1 lens tube is normally used to fix Ø25.4 mm optics and create light-tight beam paths to avoid the affection from the ambient light.

Application context
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Four rods define the axis, so every element threaded onto them starts square and centred.
Build a relay, filter block or launch module that can be moved between setups intact.
Package an optical train into a rigid unit for OEM and portable instruments.
System integration
Use these checks to connect CSSM1-50B to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
Technical FAQ
Thread: SM1. Match the thread standard and hole pitch before ordering. Metric and imperial hardware interchange only through an adapter, and a thread that is nominally similar is not necessarily the same pitch.
Material: 6061 Aluminum Alloy · Surface Processing: Black Anodized. Aluminium moves about 23 ppm per kelvin and stainless about 16. In a path where thermal drift is already budgeted, the material of the mount belongs in that budget rather than in the appearance of the part.
Size: 50 mm. Use the stated geometry and mass to fix beam height, clearance and the load carried by whatever this part is bolted to. These are the numbers that decide whether adjacent components physically collide.
Model selection
Compare CSSM1-50B with the closest available models in the SM1 Lens Tube family. Confirm option-dependent values on the final configuration before ordering.

Before you specify
Engineering context for choosing this class of component, with the tradeoffs worked through on real specifications.
Opto-mechanicsVibration, thermal drift and mechanical integration are one problem. Budget the motion at the sample, then specify the table, the isolation, the mounts and the beam height that budget asks for.
