IdealPhotonics' cage-like system is a modular optical architecture based on standardized metal rods (such as SM1/30mm) and coaxial sleeves. Through precision mechanical interfaces, it enables rapid alignment, stable fixation, and flexible expansion of optical components (lenses, mirrors, etc.), providing a highly rigid and repeatable integrated solution for complex optical paths.Using a coaxial rigid frame as its core, it is compatible with standard parts, enabling calibration-free coaxial assembly of optical components and millimeter-level modular expansion, combining vibration resistance and experimental repeatability.
