Description

(1) The CSM05-T series lens sleeve has an adjustable SM05 (0.535 "-40) external thread length at one end, allowing the Ø 1/2-inch optical element installed in the sleeve to rotate and translate along the optical axis of the sleeve system until the optical element reaches the desired position. Then, use a locking ring to secure the optical components in place. These rotatable adjustable length lens sleeves are an ideal solution for fine-tuning the first and last lenses in the lens sleeve system.

(2) The depth of the threaded hole inside the casing is 13.5mm, which is compatible with the installation of optical components up to 1/2 inch and up to 11.7mm thick. The sleeve contains a CSK05 snap ring, which is used to install the optical element into the threaded hole section during operation.
