  • LIV Test System

    Yelo Ltd.

    A light-current-voltage (LIV) test is one of the essential tests that a laser diode must go through to ensure its reliability for post production use. This test will help to verify the operating characteristics of your laser device. The test works by driving current to your laser diode and measuring the resulting voltage and light output. The results are then plotted into a graph, which is known as an “LIV curve”.

  • Measuring Spark Gaps

We offer these Measuring / Chopping Gaps with sphere diameters 100mm, 250mm, 500mm, etc. These Measuring / Chopping Gaps are designed in compact size and are light in weight, which make them portable. We offer these Measuring / Chopping Gaps at very reasonable prices.

  • Micro Spectrophotometer

    USPM-RU III - Olympus Corp.

    The USPM-RU III is a reflectometer that provides highly accurate spectral reflectivity measurements of small, curved, and thin samples without interference from rear surface-reflected light. The curved surface of the lens can be measured from a minute spot as small as ø60 µm formed on the sample surface. This provides the ability to use a goniometer to examine even the curved side lenses or other optical component.

    *Highly sensitive highly accurate multimeter in a handy compact housing*Backlit display is easy to read under any light condition (for KT7260L)*20 ranges in 6 functions*AC/DC voltage measurement up to 1000V*DC current measurement up to 10A*Resistance measurement up to 20MΩ*Audible continuity & diode tests*Transistor polarity judgement*Fuse F500mA/250V*

  • Multi-Meter

    TW3207 - Techwin(China) Industry Co., Ltd

    Multi-Meter TW3207 integrates the functions of an intelligent optical power meter module and of a highly stable light source module in one unit which can perform closed-loop tests by incorporating both modules. Individual regimes of operation can also be manually chosen using menu operation to switch functions. A perfect combination to make your optical fiber tests a lot more convenient.


    TR-36 - Tel-Instrument Electronics Corp.

    The TR-36 NAV/COMM/ELT/EPIRB Test Set is Tel-Instrument Electronics Corp. latest offering. Updated to the latest in hardware and software the TR-36 can easily provide comprehensive ramp testing in an user-friendly, light weight high-precision instrument for rapid functional testing of VOR, LOC/GS, MB, and VHF COMM (AM/FM), ELT and EPIRB avionic equipment all in a weather proof package with color display.

  • Near Ultraviolet (NUV) SiPMs

    First Sensor AG

    Silicon photomultipliers (SiPMs) from First Sensor are innovative solid-state silicon detectors with single photon sensitivity. SiPMs are a valid alternative to photomultiplier tubes. The main benefits of these detectors are high gain, extremely good timing performance and low operating voltage. They are insensitive to magnetic field and have a high integration level. The detectors are optimized for Near Ultraviolet (NUV) light detection.

  • NITlab Chassis Manager Card

    NIT Laboratory

    NITLAB designed and implemented a Chassis Manager(CM) card to control and monitor NITOS nodes. CM card is comprised of a general-purpose microcontroller, an ethernet microcontroller and a relays circuit. General-purpose microcontroller supports a tiny web server and can serve http requests such as power on/off and reset. Furthermore, it returns the operation status of the node and can support a temperature & humidity sensor and a light sensor as well.

  • Optical Sensors

    Bee Instruments

    Optical (Infra-Red) Proximity Switches with advanced and reliable technology for every application offer a flexible solution for automation, where other Proximity Switches can not perform. Optical Proximity Switches have distinct advantage of higher sensing distance over Inductive and Capacitive types. These can work more reliably in noisy electromagnetic field. As an Infra-red wavelength is used, it is immune to visible light interference.

  • Outdoor Nodes

    NIT Laboratory

    The upgraded Outdoor Nodes have been developed by the NITLab team and support MIMO operation. The new version of the Outdoor Nodes are equipped with 802.11a/b/g and 802.11a/b/g/n wireless interfaces. They also feature 2-core Intel cpus, new generation solid state drives and usb web cameras. Last but not least, each node is equipped with light, temperature and humidity sensors.

  • Panel Light-I-V Teste

    ASIV-11 - Greensolar Equipment Manufacturing Ltd.

    The Panel Light-I-V Tester (ASIV) is used to test photovoltaic panels or modules during their production. A flashlight illuminates the work piece with similar light spectrum to that of the Sun, while the electric performance of the unfinished panel or the finished module is accurately measured. With the help of the tester the user can filter out reject panels. Testing the final performance reveals changes made by alternations in the deposition recipe.

  • pH Controller

    MC122 - Milwaukee Instruments

    With Milwaukee's MC Controllers you can monitor and control pH and/or ORP levels. The Milwaukee Instruments "MC" Controllers have a user selectable set point and a visual "Power Activated" LED notification light. Power to the controller box is turned on when the reading is Above or Below ( user selected ) the selected set point. These MC Controllers are ideal for CO2 or ozone dosing.

  • Photodiode Power Sensors

    Newport Corporation

    A photodiode is a type of photodetector that is used to convert light into current so that optical power can be measured. With our comprehensive testing and direct NIST traceability our low power photodiode sensors provide measurement results you can trust when measuring optical power from free-space and fiber-optic sources. Please see our low power sensor guide for additional information.

  • Prober

    TMPF-160-256 - Taiyo Industrial Co., Ltd.

    For checking panels up to 2 inches in size. The TMPF-160-256 has an overdrive mechanism for adjusting contact pressure, along with a transparent acrylic plate for mounting test pieces so it may be used with light tables. The bump FPC used for making contact, and the contact FPC used on the checker side, are attached by screw pressure-fit connections allowing the bump FPC to be changed easily.
