  • Electrical Circuit Tester

    TE6-0705 - Hangzhou Tonny Electric & Tools Co., Ltd.

    This circuit tester is a simple but extrememly useful tool. If you are trying to diagnose and troubleshoot an electrical problem, sometimes a circuit tester can help you rule out possible causes much more quickly and easily than a DMM (Digital Multi Meter). It's quick, easy and very versatile, so the test light style of circuit tester can be a lifesaver. You can use it to check any positive circuit. Headlights not coming on? if the fuse is good, you can use a circuit tester to trace the wiring path and find out what's gone wrong. If the positive path is intact, you can also use the test light to check the grounding points of the circuit.

Featuring low backreflection and diffraction-limited lenses, these components exhibit high throughput and high optical performance, for example with focal spot sizes down to a few microns. These devices can be used to couple light to/from lasers, laser diodes, acousto optic devices, photodiodes and other fiber optic devices, and are additionally ideal for fiber packaging applications. For very high power applications, a patented fiber fusion technology is available for some of these components.

  • Distributed Polarization Crosstalk Analyzer

    PXA-1000 - General Photonics Corp.

    The PXA-1000 Distributed Polarization Crosstalk (X-Talk) Analyzer is an enhanced white light interferometer that measures space-resolved stress by analyzing stress-induced polarization cross-coupling along a length of polarization maintaining (PM) fiber. The patented design eliminates strong zero-order interference and reduces the multi-coupling interference common in traditional white light interferometers, both of which can cause “ghost” peaks in the measured signal. The removal of the “ghost” peaks enables the PXA-1000 to unambiguously identify the magnitudes and locations of actual x-talk peaks, resulting in higher measurement sensitivity, higher dynamic range, and higher spatial measurement accuracy.

  • Insertion Loss and Return Loss Testers

    Ingellen Technology Co.,Ltd

    Insertion loss refers to the fiber optic light loss caused when a fiber optic component insert in to another one to form the fiber optic link. Insertion loss can result from absorption, misalignment or air gap between the fiber optic components. Return loss is the fiber optic light gets reflected back at the connection point. The higher the return loss means the lower reflection and the better the connection is. Ingellen supply Insertion Loss and Return Loss Testers which are 100% tested on each single piece before shipment, and they are fully compliant or exceed the industry standard.

  • Spark Emission Spectrometer

    SparkCCD 6000 - NCS Testing Technology Co., Ltd.

    Model SparkCCD 6000 spark emission spectrometer uses high-resolution linear CCD (Charge-coupled Device) to perform full-spectrum scanning. It is widely used to analyze elements of a variety of base metal samples. Its advantages include unrestricted by the photomultiplier arrangement, ability to test any elements without changing the hardware, and easy maintenance. Its excitation light source is a full-digital solid-state light source with excitation energy and continuously adjustable frequency, suitable for various materials, and original position single discharge acquisition technique for improved precision, and USB-based acquisition with better adaptability.

  • Particle-Counter

    JFE Advantech Co., Ltd.

    This is a wired instrument that measures particle size distribution and the concentration of suspended particles automatically through image processing. Also, it is possible to measure particle size distribution of prepared slide sand samples. The instrument is compact and can be used in a variety of situations from field observations to laboratories. Still images are produced by emitting light pulses at the front of a CCD camera lens, which in turn, through continuous shooting, captures the particles while they are between the light source and the lens. The measurements are made in an open-cell system, where a gap works as a flow path. However, adding a flow path connected to a pump it is also possible to use nearly as a flow cell.

  • Ion Laser
