How much does an extinction ratio meter cost

Extinction ratio meters typically cost between $5,000 and $25,000, depending on brand, wavelength range, and features.Extinction ratio meters (ERMs) are precision instruments used to measure the polarization extinction ratio (PER) and polarization angle of polarization-maintaining fibers or devices. The cost varies significantly based on wavelength coverage, measurement speed, dynamic range, and additional features such as computer interfaces, logging capabilities, or compatibility with fiber splicers .Factors Affecting PriceBrand and Model: High-end brands like Thorlabs, Santec, and Newport offer benchtop meters with advanced features, which are generally more expensive than entry-level models from smaller manufacturers .Wavelength Range: Devices covering broader wavelength ranges (e.g., 400–2500 nm) tend to cost more than those with narrower ranges .Measurement Features: Meters with real-time logging, high-speed data acquisition, or auto-alignment capabilities are priced higher .Connector Compatibility: Some meters include exchangeable fiber connector adapters or support bare fiber insertion, which can influence the overall cost .Software and Control Options: Remote control via PC software or integration with optical power monitors can add to the price .Typical Price RangeEntry-level meters: Around $5,000–$8,000, suitable for basic PER measurements in labs or small-scale production .Mid-range meters: $10,000–$15,000, offering faster measurements, broader wavelength coverage, and logging features .High-end meters: $20,000–$25,000 or more, including advanced benchtop models with full automation, high precision, and compatibility with multiple fiber types . For exact pricing, it is recommended to contact the manufacturer or authorized distributor, as prices can vary based on configuration, optional accessories, and shipping.
