Explore our flagship wholesale radiometric thermal imaging solutions engineered for high spatial resolution, accurate thermal measurement, and robust operational resilience.
Shenzhen Dianyang Technology Co., Ltd. is a specialized subsidiary of VHD (Shenzhen VHD Technology Co., Ltd.), a publicly traded enterprise on the Shenzhen Stock Exchange. This strategic affiliation grants Dianyang direct access to VHD’s state-of-the-art optical laboratory facilities, automated SMT production pipelines, high-precision thermal calibration targets, and multi-tier quality control workflows.
Unlike conventional contract manufacturers, Dianyang operates with a dedicated engineering team implementing rigorous Design for Manufacturing (DFM), Design for Testability (DFT), advanced thermal radiation modeling, and EMC pre-compliance protocols. Our commitment ensures every thermal sensor, lens assembly, and processing algorithm delivers absolute measurement accuracy, low Noise Equivalent Temperature Difference (NETD), and multi-year field stability.
"By integrating uncooled VOx microbolometers with proprietary noise-reduction algorithms and blackbody optical calibration, we bridge the gap between heavy industrial thermography and accessible commercial deployment."
Our products comply with strict international regulatory regimes. We assist global clients with full compliance documentation for CE, FCC, RoHS, REACH, CB, UKCA, KC, and PSE certifications.







Understanding the critical metrics behind radiometric thermal imaging and wholesale sensor customization.
From cost-effective 96x96 and 120x90 entry-level detectors to ultra-detailed 384x288 and 640x512 focal plane arrays (FPA), our microbolometers use Vanadium Oxide (VOx) material to ensure sharp thermal contrast, pixel pitch fidelity down to 12μm, and wide spatial coverage.
Noise Equivalent Temperature Difference (NETD) measures the smallest temperature variance the camera can detect. Our sensors maintain an industry-leading NETD of <40mK (and <30mK on premium models at 30°C), making minuscule thermal bridges and electrical resistances clearly visible.
Equipped with dynamic multi-range calibration, Dianyang thermal imagers accurately capture spans from standard HVAC environments (-20°C to 150°C) up to heavy metallurgical processing and furnace analysis reaching +1200°C with emissivity adjustments from 0.01 to 1.00.
