Optical Retaining Ring (Lens Tube Locking Ring)
This product is a thin, circular optical retaining ring (locking ring) with a matte black finish, designed to secure lenses, filters, mirrors, windows and other round optical elements inside lens tubes, optical mounts and optomechanical assemblies. The ring features small spanner-wrench notches on its inner edge, allowing it to be easily tightened or removed with a compatible spanner wrench. Its low-reflectivity black surface helps suppress stray light in optical paths, making it suitable for precision optomechanical systems in laboratories, imaging devices and laser setups.

A solid-state laser is one of the most common and reliable laser types used in modern industry, medical equipment, and scientific research. Unlike gas or fiber lasers, it uses solid materials as its gain medium to generate stable, high-brightness laser beams. Thanks to its high precision, long lifespan, and compact structure, solid-state lasers have become a mainstream solution for high-precision laser processing and optical systems.
Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
In photonics and laser technology, devices that manipulate optical signals via the electro-optic effect form the backbone of precision optical systems. Electro-optic phase modulators and electro-optic deflectors are two prominent examples of this device category. As a critical hardware solution for high-speed, high-accuracy laser beam direction control, electro-optic deflectors are widely deployed across industrial and research settings. Below is a detailed overview of their core structure, key performance drivers, and primary use cases.
