Infrared Focal Plane Detector Test Device IR FPA-A
The IR FPA infrared focal-plane detector test apparatus measures pixel responsivity, responsivity nonuniformity, noise voltage, detectivity, noise-equivalent temperature difference, valid-pixel rate, fixed-pattern noise, noise-equivalent power, saturation irradiating power, dynamic range, the source's relative spectral-effect/readout-rate wording, frame rate and crosstalk. It suits cooled SWIR, MWIR and LWIR area and linear focal-plane arrays with pixel pitches of 7.5, 10, 12, 15, 25 or 30um.

Supplier Information
Langwei Optics was founded in 2024 by a team with over ten years of experience in optical precision measurement, headquartered in Chengdu. With the mission of 'Redefining precision measurement through proprietary technology, and empowering intelligent manufacturing with precision optics,' and the vision of 'Becoming a global technology leader and standard-setter in precision measurement, driving the continuous evolution of China's intelligent manufacturing with optical technology,' Langwei has built a multi-dimensional high-precision measurement product system covering optical material testing and precision metrology. All core components and complete systems are independently developed, providing measurement benchmarks that do not rely on imports for high-end manufacturing fields such as semiconductors and aerospace. We are not just a general supplier; we are a technical co-builder with our customers in the precision measurement process—present from requirement definition to solution implementation. After two years of arduous research, we successfully developed a refractometer that achieves full import substitution, filling the gap in the domestic field. We have invested 120 million RMB in Chengdu to establish an R&D and production base, aiming to become China's leading professional company for high-end scientific testing instruments.
