The current trend toward refinement in the optical inspection sector presents dual challenges to the adaptability and stability of core inspection components. Industrial machine vision manufacturers must purchase uniform-light sources separately for camera calibration; research institutions require custom-built optical inspection integrating spheres for material transmittance/reflectance testing; and aerospace entities need to replace large-aperture calibration equipment for remote-sensing payload calibration. Procuring multiple dedicated devices not only increases testing costs but also introduces inconsistencies across measurement results due to inter-device accuracy variations—a longstanding, industry-wide pain point in optical inspection.
To address this industry challenge, Jingyi Optoelectronics has launched the JY-FOIS84 Universal Optical Inspection Integrating Sphere. Leveraging breakthroughs in both modular design and proprietary coating technology, this device achieves full-scenario optical inspection coverage with a single unit. As the core component for optical homogenization and field conversion, an optical inspection integrating sphere’s fundamental value lies in transforming incident light—regardless of its original form (e.g., highly collimated laser beams, divergent LED surface illumination, or chaotic ambient scattered light)—into a spatially uniform, spectrally consistent light field via multiple diffuse reflections off its inner wall. Its performance thus directly determines the upper limit of optical inspection accuracy.
The JY-FOIS84 features a fully modular port-design system, enabling users to rapidly swap functional accessories according to immediate testing needs—without redesigning or re-manufacturing the sphere body itself. Equipped with the optional light-source module, it serves as a broadband uniform light source for calibrating cameras and remote-sensing payloads; integrated with a spectral detection module, it enables precise measurement of laser power and spectral distribution; and fitted with a sample-holding module, it supports direct transmittance and reflectance measurements for thin films, coatings, and other materials—delivering true “one-sphere, multi-function” capability. For users requiring customization, port size and position can be flexibly adjusted to accommodate unique optical-path layouts within self-developed optical systems—eliminating the need to revise existing test protocols solely for hardware compatibility. Overall, its return-on-investment ratio exceeds that of specialized integrating spheres by more than 50%.
The performance ceiling of an optical inspection integrating sphere is largely determined by the diffuse-reflective coating applied to its inner wall. Many users have experienced significant accuracy degradation after just one to two years of use—due to yellowing or peeling of the coating. Jingyi Optoelectronics’ proprietary high-stability diffuse-reflective coating—specifically engineered for this universal integrating sphere—not only exhibits excellent Lambertian characteristics and <0.3% spatial uniformity deviation, but also maintains >97% reflectance across the full 350–2500 nm spectral range. Furthermore, it withstands rigorous reliability testing—including 1,000 hours of intense light aging and thermal cycling across extreme temperature ranges—with zero yellowing or coating delamination. Long-term operational accuracy remains firmly aligned with factory specifications. Notably, many users overlook how minute differences in coating reflectance can trigger amplified performance effects. Due to the integrating sphere’s inherent “sphere multiplication effect,” every 2% increase in coating reflectance boosts final output radiance by over 40%; in the near-infrared band (>1400 nm), this amplification exceeds 200%. Jingyi’s high-reflectance coating maximizes this advantage—ensuring robust, usable optical signal strength even under low-light or infrared conditions, and improving overall measurement accuracy by more than 20% versus industry-standard integrating spheres.
The JY-FOIS84 Universal Optical Inspection Integrating Sphere is already deployed across multiple sectors. In industrial machine vision, it delivers uniform light fields with brightness and color temperature regulation accuracy of ±0.5%, fully satisfying international standards for flat-field correction, linearity testing, and dark-noise evaluation of industrial cameras—improving test efficiency by 60% compared to conventional calibration approaches. In aerospace R&D, large-diameter ports can be customized to meet diverse remote-sensing payload testing requirements, achieving <0.2% spatial uniformity deviation—meeting the stringent accuracy demands of on-orbit remote-sensing calibration. In materials testing, a single unit covers transmittance/reflectance measurement, laser power quantification, and spectral analysis—reducing total testing cost by over 40% versus purchasing multiple specialized integrating spheres.
As optical inspection evolves toward intelligence and integration, Jingyi Optoelectronics continues advancing integrating sphere technologies. The current JY-FOIS84 series already incorporates reserved interfaces for intelligent control modules, enabling seamless future integration with automated test systems and facilitating unattended batch inspections—offering the entire industry a higher-value, cost-effective core component for next-generation optical inspection.
