Optical thin-film coating technology is used in an extremely wide range of applications and touches nearly every aspect of modern daily life and industrial technology. From everyday mirrors, luxury accessories, automotive components, and eyewear to smartphones, cameras, optical telescopes, flat-panel displays, security surveillance systems, and high-performance lighting, advanced optical coatings play a critical role. At ROCOES Electro-Optics Co., Ltd., our specialized expertise lies in precision optical thin-film deposition and custom optical filter manufacturing. A key overview of our application fields is outlined below:
Infrared cutoff filters (IR-Cut Filters) for digital cameras and mobile camera modules, professional photographic filters (CPL polarizers, ND filters), dynamic stage lighting color filters, water fountain/aquatic show color presentation, architectural feature illumination (bridges and skyscrapers), gaming arcade screen filters, retail display window illumination, fiber-optic light guide systems, museum UV-blocking protective filters for artifact preservation, high-CRI LED lighting optics, anti-reflective display protective windows (AR Glass), and LCD/DLP projector optical engine modules.
Image intensifier tubes and optics for night vision devices (NVDs), high-intensity searchlights, long-range infrared (NIR/SWIR) night surveillance optics, optical gun sight reticles/visors, laser rangefinders, and electro-optical defense sensors.
Retail and logistics barcode scanners, laser leveling instruments, cross-line alignment lasers, photomicrography systems, cold-light (green/blue) surface defect inspection light sources, LED testing and measurement instruments, UV curing and UV printing systems, automatic welding helmet protective filter plates, analytical instrument optical filters, and Automated Optical Inspection (AOI) machine vision systems for Industry 4.0 production lines.
High-throughput optical bandpass filters for dental light-curing devices, fluorescence excitation and emission filters for biomedical diagnostics (DNA sequencing and qPCR instruments), minimally invasive surgical endoscopes, and precision medical imaging optics.
At ROCOES Electro-Optics (established in November 1992), we continuously refine our Physical Vapor Deposition - Electron Beam Gun Evaporation (PVD-EBGE) coating processes and expand our comprehensive product lines to deliver world-class optical performance that meets international standards. Whether you are developing a next-generation optical system, seeking specialized spectral filtering solutions, or optimizing existing optical components, we welcome you to contact our engineering team. Beyond supplying precision optical filters and mirrors, we are eager to collaborate with you to explore and pioneer new applications of light.
