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.

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.

Mode-Conditioned Light Sources
-
Thorlabs' Mode-Conditioned Light Sources are fiber-coupled LED sources that have an output with a flat-top profile in the far field. Common applications include the testing of multimode fused fiber components as well as verification of modal behavior in fiber-based setups. Standard fiber-coupled LED sources can have a range of output profiles that are usually not uniform and vary from source to source. This can be dependent on emitter orientation, alignment with fiber tip, and connector assembly. These mode-conditioned sources have been engineered to distribute light evenly into all transverse modes, resulting in an equilibrium modal distribution at the output. The front panel includes an adjustment knob to control the power and an output port that accepts 2.2 mm wide-key FC/PC connectors. A DS15 15 V power supply with a location-specific plug is included with each device.

Fiber Optomechanics
-
The versatile FiberBench product line includes Single and Multi-Axis FiberBenches as well as a wide variety of compatible components ranging from beamsplitter modules to wave plate units. FiberBenches form the foundation of a nearly infinite array of miniature fiber optic systems that customers have been building for the last decade. When used with the FiberPort Collimators/Couplers, a complete optical circuit can be constructed. The Fiber Launch Platforms are ideal for coupling a free space laser into a single mode, multimode, or polarization-maintaining fiber. Other accessories include fiber mounts, fixed and kinematic collimator adapters, and L-bracket mating sleeves.

Light Analysis
-
Welcome to Thorlabs; below you will find links to detectors and instrumentation that measure the various properties of light, a subset of our entire line of photonics products. Thorlabs offers an extensive selection of instruments that measure the properties of light. Our versatile power and energy meters can be used with over 25 different sensors in order to make NIST-traceable power and energy measurements. If the convenience of a meter is not desired, our selection of detectors includes basic photodiodes (uncalibrated and calibrated), photodetectors (biased, amplified, and avalanche), CCD and CMOS arrays, position detectors, integrating spheres, and photomultiplier tubes. The Beam Characterization category contains beam profilers (camera and scanning slit), a wavefront sensor, spectrometers, and interferometers, while the Polarimetery link leads to a selection of instruments used to measure and control the polarization of light.

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.
