Optical lens sleeves are commonly used to secure Ø25.4mm optical components or for light path shielding, preventing ambient light from affecting the system. The combination of lens sleeves can be extended in length, facilitating the rapid assembly of compact optical systems. By positioning the retaining ring at the required location inside the lens sleeve using a retaining ring wrench, separation and fixation of optical components can be achieved.
