Simultaneous Determination of Cu²⁺, Co²⁺ and Ni²⁺ by Fiber-Optic Spectroscopy in the Visible and Near-Infrared Range

The simultaneous quantitative determination of dissolved Cu²⁺, Co²⁺ and Ni²⁺ ions is important in many fields. These include metallurgy, geology, industrial wastewater analysis and the monitoring of biotechnological processes. In many cases, their concentrations need to be measured directly at the sampling site or in-line during an operating process. The Challenge of Metal Ion Monitoring […]

Introducing FlexiRay® Square-Core Laser Cables

Posted on: 
25 August 2025

art photonics GmbH is proud to announce a significant addition to our portfolio: the new FlexiRay® Square-Core Silica Laser Cable, engineered to enhance the performance and efficiency of diode laser light transmission.

While traditional round-core fibers have long been the industry standard, an increasing number of advanced applications demand a more specialized solution for beam shaping and power distribution. Our new FlexiRay® cables address these challenges by delivering capabilities that conventional round fibers cannot match.

Key advantages include:

  • Homogeneous Power Distribution: The square core geometry produces a highly uniform beam profile, which is critical for applications requiring consistent energy density.
  • Enhanced Coupling Efficiency: Power transfer from diode lasers and to square detectors is significantly improved, minimizing loss and maximizing system performance.
  • High Durability: These cables are designed to operate reliably in demanding environments, with a wide temperature range of -40°C to +130°C.

Built for reliability, FlexiRay® cables are terminated with D80 or HP-SMA connectors. Each connector features an integrated key, ensuring repeatable and secure alignment to maintain optimal performance. The entire assembly is protected by robust tubing, making it suitable for demanding medical, industrial, and scientific systems.

Recognizing that every application is unique, art photonics offers full customization for the FlexiRay® line. The fiber structure and overall cable configuration can be tailored to meet your specific project requirements.

If you are facing challenges with laser transmission or beam shaping, our team is ready to help. Contact us today to discuss your application and discover how our square-core fiber technology can provide the perfect solution.
