icrolight is a high-tech enterprise specializing in the R&D, manufacturing and sales of active and passive photonic devices for microwave photonics, LiDAR ranging, gas sensing, fiber optics and photomedicine.
Against the evolving demands for military‑grade hardware, rail transit equipment and heavy‑duty machinery that run under high‑shock vibrating conditions, anti‑loose connectors serve as indispensable hardware for stable power delivery and high‑speed signal transmission.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
For pulsed laser and full-spectrum optical testing, photodiodes and thermopiles have inherent drawbacks. Photodiodes show weak response in infrared band, while thermopiles feature slow response and cannot capture nanosecond narrow pulses.
