Newport Wavelength Reference Standard 2010WR-A

Newport Wavelength Reference Standard 2010WR-A

The Newport Wavelength Reference Standard 2010WR-A is a calibration tool designed for use with optical wavelength measuring devices such as Optical Spectrum Analyzers (OSAs). It provides stable reference wavelengths over multiple regions of interest in the optical spectrum, ensuring accurate measurements across a wide range of wavelengths.

Key Features:

• Multipoint Calibration: The device uses a multipoint calibration technique, which involves taking calibration error measurements at multiple known wavelengths. This approach improves measurement accuracy over a wider range compared to single-point calibration methods[2][3].
• Gas Cells: The reference standard utilizes gas cells containing mixtures of gases such as methane and acetylene. These gases produce sharp and deep absorption lines at known wavelengths when illuminated by a broadband source[1][3][4].
• Segmented Calibration: The calibration process can be extended by segmenting the wavelength range and using separate calibration constants for each segment. This allows for higher accuracy in critical wavelength regions and flexibility in choosing different correction models for different segments[2][3].
• Statistical Analysis: The calibration method includes statistical analysis to remove outlying data points and calculate weighted averages, ensuring robust and reliable calibration constants[2][3].

Applications:

• Optical Spectrum Analyzers (OSAs): The 2010WR-A is primarily used for calibrating OSAs, which are critical in various optical and photonic applications.
• Tunable Laser Calibration: It can also be used for calibrating tunable lasers, ensuring precise wavelength control.
• Fiber-Bragg Interrogation: The device is applicable in fiber-Bragg interrogation systems, which are used in sensing applications.
• Gas Sensing: The gas cells can be used in gas sensing applications, leveraging the absorption lines of different gases[4].

Technical Specifications:

• Gas Cell Configurations: Various configurations are available, including different gas mixtures and path lengths up to 80cm with folded optics in multi-pass housings[4].
• Fiber Options: The device uses Corning SMF 28e Ultra fiber, optimized for 1310nm ± 40nm or 1550 ± 40nm, with FC or SC, PC or APC connectors[4].
