Fiber End Face Interferometer
-
Thorlabs' GL16 End Face Interferometer measures and images the end face geometry of single- and multi-fiber connectors. A non-contact technique called scanning white-light interferometry (SWLI) provides high accuracy, repeatability, and reliability for fiber connector testing, particularly for pass/fail testing using IEC or Telcordia requirements. The system can be controlled locally through the touchscreen display or remotely through a browser-based application (see Software tab for details), allowing it to be easily integrated on the production floor.

Optical Isolators
-
Thorlabs manufactures a wide selection of narrowband and broadband free-space optical isolators (Faraday isolators) that operate in spectral ranges from 365 nm to 9.80 µm, including high-power options, as well as fiber isolators designed for wavelength ranges from 650 to 2010 nm for polarization-independent versions and 770 nm to 2010 nm for polarization-dependent versions. For customers whose needs are not met by our stock selection, we offer a custom isolator service that can combine the best features across our entire isolator family. The Optical Isolator Selection Guide displays wavelength ranges and isolator types for all stocked isolators.

Portable Connector End Face Geometry Interferometer
-
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.

Scientific Cameras
-
Thorlabs' Scientific-Grade Cameras are specifically designed for microscopy and other demanding applications. The Zelux™ CMOS cameras have small footprints and provide cost-effective solutions for general-purpose imaging applications. Kiralux® cameras have CMOS sensors with high quantum efficiency in a compact housing and are offered in monochrome, color, NIR-enhanced, and polarization-sensitive versions. Our polarization-sensitive CMOS camera is ideal for materials inspection, flaw detection, and other advanced techniques using polarization. The Quantalux® monochrome sCMOS cameras are fast frame rate imagers that combine high dynamic range with extremely low read noise for low-light applications. They are available in either a passively cooled compact housing or a hermetically sealed TE-cooled housing. We also offer scientific CCD cameras with a variety of features, including versions optimized for operation at UV, visible, or NIR wavelengths; fast-frame-rate cameras; TE-cooled or non-cooled housings; and versions with the sensor face plate removed. An intuitive software package, API and SDK for developers, and third-party software support provide options for custom system control and image acquisition.

Galvo-Resonant Scan Head and Controller
-
Our LSK-GR08(/M) Galvo-Resonant Scanner contains one resonant scan mirror and one galvo scan mirror that deflect an incident laser beam in X and Y, respectively. Identical to the galvo-resonant scanner used in our Bergamo® II multiphoton microscopes and complete Cerna®-based confocal systems, the 8 kHz resonant frequency of the resonant scan mirror enables much higher-speed scans than a galvo-galvo system. In our Bergamo system, the scanner can achieve 30 fps at 512 x 512 pixels image resolution.

Two-wavelength SM WDMs
-
Wavelength Division Multiplexers (WDMs) are used to combine or split two different single mode signals with low insertion loss. Thorlabs' WDMs featured on this page are manufactured using Fused Biconic Taper (FBT) technology and are designed for common NIR and telecom wavelengths (see the table to the right for options). They are an ideal solution for combining pump and signal wavelengths in fiber lasers and amplifiers or for combining telecom signals. Our WDMs have undergone extensive testing to ensure they meet or surpass Telcordia requirements; please see the Reliability Testing tab for details.

Fourier Transform Optical Spectrum Analyzer, 600 - 1700 nm
OSA202C
-
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.
