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.
Developed by RealLight (Beijing), the R7M high‑power diode laser module belongs to the AW multi‑functional laser product family.
GYOPTICS 30 W collimated isolator is a highly‑reliable passive optical component optimized for 1064 nm high‑power laser systems. Characterized by low insertion loss and superior backward‑light suppression capability, it effectively blocks reflected light traveling back toward the laser resonator, eliminating back‑reflection‑induced instability and protecting fiber or solid‑state laser sources during long‑term operation.
Santec introduces the HSL‑20‑C‑E swept laser. Built on proprietary MEMS technology, this compact integrated light source combines high‑speed scanning and long coherence length, optimized for SS‑OCT imaging systems. Configurable start trigger and k‑clock outputs are available to meet development requirements for medical‑biological imaging and industrial non‑destructive inspection equipment.
