Optical Power And Energy Meters

-

Thorlabs, Inc.

Thorlabs, Inc.

Thorlabs' expanding line of optical power and energy meters includes power meter consoles, a large selection of sensor heads, a wireless power meter with a built-in photodiode sensor, and a fiber optic power meter designed for use in the field. The consoles (PM100, PM400, and PM300 Series) when paired with our extensive line of power and energy sensors provide calibrated (NIST traceable) measurements across a broad range of powers, energies, and wavelengths. The console(s) and sensor(s) can be purchased individually or as bundles based on our most popular console and sensor pairings. The sensor calibration data is stored in the sensor head and is automatically read by the console, which allows the user to use multiple sensors with the same console. Compatible sensors are easily identified by the red c-series connector. All of our old A/B-Type sensors are available with the new connector; plus, we have continued to expand our power and energy sensor product lines.

Thorlabs, Inc.

Thorlabs, Inc.

Welcome to Thorlabs; below you will find links to optical components and systems, a subset of our entire line of photonics products. All single element optical components can be found under the optical elements link with the exception of optical components that have polarization properties since they have a separate link. Multi-element systems like beam expanders and objective lenses as well as interferometers, fiber collimators, reference cells, modulators, and other optical devices can be found by choosing the optical systems link. Thorlabs also manufactures an extensive line of free-space and fiber optic isolators; stock items ship the same day that they are ordered while our custom orders benefit from our streamlined design and manufacturing process, which minimizes lead time.

Galvo-Resonant Scan Head and Controller

-

Thorlabs, Inc.

Thorlabs, Inc.

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.

Mode-Conditioned Light Sources

-

Thorlabs, Inc.

Thorlabs, Inc.

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.

Motion Control

Thorlabs, Inc.

Thorlabs, Inc.

Welcome to Thorlabs; below you will find links to our selection of Motion Control products, a subset of our entire line of photonics products. Thorlabs’ motion control products are separated into manual and motorized linear and rotation stages, multiaxis platforms, actuators, and controllers. The manual and motorized stages can frequently be configured into 1-, 2-, or 3-axis solutions. Since many of the stages are available in either manual or motorized versions, creating a custom system is easy. For nanopositioning applications like waveguide and fiber coupling, our line of multiaxis flexure stages are ideal. Both the motorized stages and the multiaxis platforms are supported by a complete line of controllers for the various motors and piezoelectric actuators. In addition, we support custom and OEM motion control applications with an extensive line of manual, motorized, and piezo actuators as well as threaded adjustment screws.

Fourier Transform Optical Spectrum Analyzer, 350 - 1100 nm

OSA201C

-

Thorlabs, Inc.

OSA201C - 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.
