Ultrafast Photodetector with Current Monitor, 700 - 870 nm, DC - 25 GHz, FC/PC
DXM25CF
-
The DXM25CF Ultrafast Detector is a DC - 25 GHz, fiber-coupled, GaAs-based photodetector designed for applications in the 700 nm - 870 nm wavelength range. The core element of the detector is the fiber-coupled, hermetically sealed, microwave detector module. For convenience and simplicity of use, the module is mounted inside a rugged housing that includes a rechargeable battery, current monitor circuitry, and a digital display of the DC photocurrent.

Premium Microwave Cables And Adapters
-
Thorlabs' Microwave Cables and Adapter Cables are flexible, high-performance, coaxial cable assemblies designed for use out to 50 GHz, depending on connector type (see the image to the right). The design gives these cables flexibility while maintaining optimal performance. They exhibit low VSWRs (Voltage Standing Wave Ratios) over the usable frequency range, as well as low insertion losses (see the Specs tab). These cables are each tested to ensure performance.

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.

Detectors
-
Thorlabs' photodetectors are capable of detecting light throughout the UV, VIS, NIR, IR, and THz spectral regions. Our photodetectors feature sensors that enable properties such as intensity, power, intensity distribution, wavefront shape, energy, and wavelength to be measured. We offer unmounted photodiodes as well as amplified, biased, and avalanche photodetectors. Thermal power detectors are available unmounted, mounted on a PCB, or mounted on an aluminum plate. Also available are position-detecting sensors, integrating spheres, and an acoustic detection module.

2-Wavelength, Polarization-Maintaining WDMs
-
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.

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.
