Company Profile
Entropy Light was founded in 2025 and is headquartered in Longhua District, Shenzhen, Guangdong Province. As a high-tech enterprise specializing in the R&D, manufacturing, and sales of passive optical components, the company operates 500 square meters of modern facilities with over 30 employees, including more than 10 technical professionals.
Entropy Light products cover most of the visible and near-infrared spectrum, offering 400nm–2050nm band components including fiber collimators, isolators, circulators, couplers, combiners, polarizers, WDMs, bandpass filters, mirrors, rotating mirrors, attenuators, and FBGs. We manufacture these devices using various fiber types: single-mode, multi-mode, polarization-maintaining (PM), double-clad, specialty fibers, RC80, and custom fibers. In terms of power handling, our 1.0μm isolators support up to 100W continuous wave and peak powers of 30kW for ultrafast lasers.
We are dedicated to bringing fiber optic components to every industry that relies on them, empowering our clients to achieve continuous breakthroughs in their fields through our expertise. Our current applications span: fiber sensing, biomedical engineering, optical communications, fiber lasers, aerospace, radar detection, optical metrology, quantum communication, ultrafast lasers, and more. We have extensive experience supplying mature solutions in quantum communication, ultrafast lasers, medical OCT, machine vision, EDFA, high-power EDFA, DTS, and other established sensing domains, with stable mass production capabilities. To better serve the domestic market, we have restructured our operations from the ground up. Guided by the principle of "finding greatness in the ordinary and craftsmanship in the details," we deliver fast, efficient, honest, and enthusiastic service to the clients who trust us.
