    Infinity-CLW is an autonomously deployable data logger for long-term chlorophyll and turbidity measurements. The light sources (LEDs) of chlorophyll and turbidity sensors are highly stable, Minimizing the change over time. The instrument has a mechanical wiper that periodically sweeps to inhibit biological growth on the optical window. The turbidity sensor has a good correlation with SS (Suspended Solid) over the range. Infinity-CLW provides Highly accurate and long-term stable chlorophyll and turbidity data in oceans, rivers and freshwater.

  • METER RELAYS

    Arga Controls

    These relays contain an extra pair of output terminals which run analog, digital or bar meters. They also contain lights to indicate status. Meter Relay Modules may be used with any 0-1 mA analog or 0-2 VDC digital meter. Two or more meters may be driven by one module (or multiple monitoring can be accomplished using two or more modules for a single meter). The meter relay modules come with internal or ex- ternal signal conditioning.

  • Quantum-Limited Nanowatt Photoreceiver

    QL01 Family - Hobbs ElectroOptics

    The QL01-A/B are the first of a family of advanced photoreceivers from Hobbs ElectroOptics. Offering a previously unattainable combination of low noise and high speed, they allow measurements at the quantum (shot noise) sensitivity limit in a full 1 MHz bandwidth at light levels from as low as 35 nanowatts up to a few microwatts. The QL01s are all-new designs based on expertise gained through our own research and from designing dozens of advanced instruments for our consulting clients.

  • Receiver Optical Sub-Assembly (ROSA)

    FBR4102PB - Macom Technology Solutions Inc.

    The MACOM FBR4102PB is a 4 x 25G/28G 1310nm LAN-WDM Receiver Optical Sub-Assembly (ROSA), consisting of an Optical Demultiplexer to separate 4 wavelength light signals, high-sensitivity highly-reliable PIN photodiodes and high performance low power consumption MACOM quad Trans-Impedance Amplifier (TIA). The ROSA is assembled in a hermetic-sealed package with an LC receptacle for optical input and two flex circuits for DC/RF electrical connections. The ROSA is best suitable for CFP, CFP2, CFP4 and QSFP28 applications.

  • Silicon photomultipliers (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.
