Photonic sensing and analysis harnesses lasers and optics to probe materials by examining their light interactions, yielding rapid and non-destructive insights into their chemical, physical, and biological properties. This approach underpins advances in environmental monitoring, medical diagnostics, and industrial quality control.
Researchers, engineers, and professionals in these industries explore cutting-edge applications in imaging, lasers, biophotonics, and remote sensing, with focus on technology transfer to address real-world challenges in optics and photonics. In this dynamic landscape, laser manufacturers play a crucial role by developing innovative laser systems that serve as the backbone for many photonic applications.
Yokogawa supports this innovative landscape by offering a wide range of high-performance optical measuring instruments and solutions, such as optical spectrum analyzers, wavelength meters, and high resolution reflectometers. Yokogawa OSAs feature MWIR and visible wavelength measurement capabilities, with exceptional accuracy, resolution, and dynamic range.
This application note introduces free space light measurement jigs for measuring the emission spectrum of a light source that propagates in free space or the optical transmission spectrum of an optical filter. It describes four types of jigs for light sources and one type for filters.
To accurately measure pulsed light using an optical spectrum analyzer (OSA), it is necessary to understand the characteristics of the OSA and select the appropriate measurement method and settings.
We have developed the AQ6375 Optical Spectrum Analyzer grating-based desktop optical spectrum analyzer, which can measure an optical spectrum over a wide wavelength range from 1.2 to 2.4 m with high wavelength resolution at high speed. Despite the popularity of desktop optical spectrum analyzers in the telecommunication wavelength region, a large-scale optical spectrum measurement system with a monochromator has commonly been used for measuring the long wavelength region, and so there was a need for a desktop optical spectrum analyzer for long wavelengths. Deep optical absorptions appearing in the long wavelength region around 2 m caused by CO2, NOX and H2O are attracting attention in the environmental and medical fields, and thus sensitive measuring equipment by laser absorption spectroscopy using a near infrared semiconductor laser is becoming more popular. With excellent optical spectrum measurement capabilities (high resolution and high speed), operability and maintenance performance, the AQ6375 Optical Spectrum Analyzer optical spectrum analyzer will contribute to the performance improvement and spread of near-infrared semiconductor lasers used in laser absorption spectroscopy.
