🔩 Opto-Mechanical Modules by Yighen

Integrated Optical Systems for Imaging, Laser & Sensing Applications

🔧 What Are Opto-Mechanical Modules?

Opto-mechanical modules are complete assemblies that integrate optical lenses, mirrors, filters, or lasers with precision mechanical structures such as lens barrels, mounts, housings, and motion systems. These modules are essential in ensuring alignment stability, environmental protection, and performance consistency across varying conditions.

At Yighen, we go beyond single optical components—we deliver application-ready optical subassemblies, from concept to production.
