Fourier Transform Optical Spectrum Analyzer, 600 - 1700 nm

OSA202C

Thorlabs, Inc.

OSA202C - Thorlabs, Inc.

Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.

2-Wavelength, Polarization-Maintaining WDMs

Thorlabs, Inc.

Thorlabs, Inc.

Thorlabs' Fused Polarization Maintaining (PM) Wavelength Division Multiplexers (WDMs) combine two wavelengths of light in PM fiber while maintaining the polarization of the incident light. These WDMs are reversible; they can also be used to split two discrete wavelengths entering the common port into two separate output ports. They are not designed to split the output from a broadband source. PM WDMs are often used for pump / signal applications that incorporate erbium-doped or ytterbium-doped fiber amplifiers. They can be readily customized for a wide variety of applications, enabling rapid design cycles and new project builds. For custom requests, please contact Tech Support.

Portable Connector End Face Geometry Interferometer

Thorlabs, Inc.

Thorlabs, Inc.

Thorlabs’ Vytran® Connect-Chek® Interferometer automatically and precisely measures radius of curvature, apex offset of polish, and fiber undercut or protrusion on any PC or APC, single-fiber connector. The CC6000 interferometer uses a non-contact tilted-phase-analysis technique for fast, reliable measurements of connector end faces. This compact interferometer has a carrying handle and must be attached to a desktop or laptop computer (not included) with a standard USB 2.0 port for operation. The included CC6000 software, which is used to control the interferometer, can be installed on a computer with the minimum requirements in the table below. Designed for use in both the factory and the field, this interferometer provides crucial quality information needed to assure long-term performance of fiber optic connectors. One CC250P Mount for Ø2.50 mm PC Connectors and one RT250P Reference Tool for calibrating the CC250P mount are included with the CC6000 interferometer; mounts and reference tools that enable measurement of other PC or APC, single-fiber connectors are available separately below. When used with an appropriate mount for APC connectors, the CC6000 interferometer is also capable of measuring the APC angle and key error.
