Keystone Series ns Green light 532 nm Laser Keystone-532-20
The Keystone series industrial 20w/40w nanosecond green lasers combine advanced semiconductor-pumped laser and acousto-optic modulation technologies with efficient frequency conversion and precise temperature control. They offer high stability, long life, high performance and low cost for demanding, high-volume, cost-sensitive applications. They are particularly suitable for solar-panel scribing, laser ablation, high-speed PERC-cell grooving and laser-assisted selective diffusion. Compact construction and an easy-to-use interface facilitate integration into laser processing equipment.

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.
