Application Note: Measuring Ethanol and Methanol Mixtures with ATR Fiber Probes

In the high-stakes environment of complex chemical processing, the ability to distinguish and quantify components like ethanol and methanol in real-time is often the deciding factor between a strictly controlled reaction and an off-spec batch. Traditionally, operators have relied on manual extraction for laboratory analysis. However, this method introduces significant delays and safety risks that […]

How to Measure ATR Spectra Directly in Solution with Fiber Optic Probes

Moving Beyond the Bench: In-Line FTIR Monitoring with ATR Probes For decades, Attenuated Total Reflection (ATR) has been a standard technique for FTIR spectroscopy. However, most users are restricted to standard ATR inserts or benchtop accessories. While effective for static lab samples, these setups introduce a critical bottleneck: the sample must be extracted from the […]

Square-Core Silica Laser Cable

Main features:

  • Homogeneous power distribution and enhanced coupling efficiency
  • High durability and thermal stability
  • Precision D80 and HP-SMA  connectors with a key alignment
  • Customizable cable designs and configurations
  • For applications with a beam shaping

Description

FlexiRay® Fiber Optic Laser Cables are engineered for efficient, high-power laser light transmission in medical, industrial, and scientific systems. These cables feature square-core double-clad silica fibers, offering improved coupling efficiency with square detectors or light sources - particularly with diode lasers—and enhanced beam homogenization over short distances.

With robust protective tube, connectors and precision-polished fiber ends, FlexiRay® cables maintain secure alignment, minimize power loss, and reduce the risk of thermal damage. Fiber structure and cable configuration can be custom-tailored to meet specific application requirements.
