  • Professional Circuit Tester

    TE6-0713 - 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.

  • Tone and Probe Kit Cable Tracer

    PR-06 PLUS - Pansco, Ltd

    Net Probe Plus is a multi-function probe especially for today’s network environment, cable typically are terminated end in HUB or switch ports.

  • Monochromators

    Bentham Instruments Ltd

    Diffraction gratings are specified by a line density in grooves per millimetre. The higher the density, the greater light is dispersed resulting in a relatively limited spectral extent. Furthermore, in general , the higher line density gratings are optimised for short wavelength use and vice versa. One must take into account the available grating(s) and the operation range of such before deciding how many gratings are required to cover a given range. Where multiple gratings are required, one can opt for a multiple-grating monochromator which would allow performing a spectral measurement over a great range, or whether a single (interchangeable) grating monochromator is used and the measurement performed in two or more parts.

  • Colorimeter

    K10-A - Klein Instruments Corp

    The Klein K10-A has long been regarded as the industry standard in LCD calibration. It's enhanced optics give it a 3X advantage in sensitivity over the original K-10 SF. Known for it's superior speed, the K10-A can stream intensity data in 3.2 milliseconds, and can provide color data in 125 milliseconds. The Klein K10-A is also extremely sensitive and color accurate. Large photo-diodes give the probe superior performance even in extremely low light (down to 0.00006 cd/m2). Klein diodes are very large; 5mm x 5mm each, and are thermally stable and linear to report the highest degree of accuracy. The unparalleled speed and iconic design of this colorimeter have made it the most widely known Klein product.

  • CEP Stabilised Systems

    Laser Quantum Ltd.

    With pulse durations approaching the single cycle limit, the phase relationship between the carrier and its envelope becomes increasingly important. Controlling the carrier envelope phase (CEP) enables the exploration of a whole new area of extreme nonlinear physics where the relationship between the phase of the carrier wave and its envelope becomes crucial to the observed phenomena, e.g. in attosecond physics, where the front end of the machines generating isolated attosecond light pulses traditionally are based on CEP-stabilized oscillators. Another field which has opened up is the exploration of CEP dependent effects in electron emission spectroscopy, or more generally in the field of nano optics, plasmonics and femtosecond electron point sources.
