In the optoelectronic testing industry, many laboratories and small-to-medium manufacturers face a common challenge: to conduct three distinct optical experiments—camera calibration, material transmittance testing, and laser power measurement—they must purchase three specialized laser integrating spheres. This not only incurs high procurement costs but also results in low utilization rates. Moreover, if an ad-hoc or custom test requirement arises—such as adding a non-standard port—the lead time for customization can exceed two weeks, significantly delaying R&D progress.
Many may not realize that, at its core, a laser integrating sphere functions as an “optical light mixer.” Whether the incident light is a directional laser beam or a diffuse ambient source, once it enters the hollow spherical cavity, it undergoes dozens—or even hundreds—of diffuse reflections off the inner wall’s coating. This process ultimately yields a spatially uniform, omnidirectional light field—providing a stable, reproducible reference for subsequent optical parameter measurements. The accuracy and reusability of a laser integrating sphere hinge critically on two key performance indicators: (1) the stability of the inner wall’s diffuse-reflective coating, and (2) the structural adaptability and modularity of the sphere itself.
Addressing widespread industry pain points—including poor reusability and coating degradation—Jingyi Optoelectronics has launched the JY-FOIS84 Universal Laser Integrating Sphere, featuring technical innovations across both material composition and mechanical design.
First, at the coating level: Jingyi’s proprietary diffuse-reflective coating delivers excellent Lambertian characteristics across the full standard optical spectrum (350 nm to 2500 nm), maintaining consistent reflectance over time. It resists yellowing and delamination—even under frequent, high-intensity laser exposure—and ensures measurement deviations remain within acceptable limits for over three years of continuous operation, fully compliant with industry standards.
Second, regarding structural design: The JY-FOIS84 adopts a fully modular, universal port architecture. Users can freely configure port size and position according to specific test requirements and seamlessly switch functionalities by attaching compatible modules:
- With an optional LED light source module, it serves as a uniform light source for industrial camera flat-field calibration and radiance calibration of remote-sensing instruments;
- With a sample-holding module, it enables transmittance and reflectance measurements for thin films and optical lenses;
- With a detector interface module, it directly supports laser power and spectral parameter measurements.
This true “one-sphere-multiple-functions” approach substantially reduces procurement costs compared to buying multiple dedicated integrating spheres.
The JY-FOIS84 has already been deployed in numerous university laboratories and optoelectronic testing enterprises across China. For instance:
- In industrial vision inspection, manufacturers use the JY-FOIS84–based calibration system to perform end-to-end characterization of CMOS/CCD sensors—including spectral response, dark noise evaluation, and linearity correction—with a uniform light output exhibiting surface uniformity exceeding industry benchmarks for camera performance testing.
- In advanced materials R&D, researchers employ it to measure the reflectance of novel infrared coatings, achieving markedly improved data repeatability versus conventional integrating spheres—cutting testing cycles significantly.
Jingyi Optoelectronics holds relevant certifications, maintains a consistently high factory pass rate, and offers PTFE-based reflective coatings (with average reflectance meeting industry-accepted thresholds), plus customizable sizes and interface configurations. Comprehensive pre-sales and after-sales technical support is provided.
As optoelectronic testing expands into new application domains—including consumer electronics, automotive sensing, and aerospace remote sensing—versatile, interoperable general-purpose testing equipment has become the mainstream trend. Building upon the JY-FOIS84 platform, Jingyi is advancing data-driven enhancements: upcoming versions will integrate AI-powered spectral analysis and automated data upload capabilities, delivering an out-of-the-box, one-stop optical testing solution—and further lowering the entry barrier for optoelectronic testing.
