    The Model 2502 Photodiode Meter is designed to increase the throughput of Keithley's LIV (light-current-voltage) test system for production testing of laser diode modules (LDMs). Developed in close cooperation with leading manufacturers of LDMs for fiberoptic telecommunication networks, this dual-channel instrument has features that make it easy to synchronize with other system elements for tight control over optical power measurements.

  • 40G - Optical Receivers

    Company: Discovery Semiconductors

    Discovery Semiconductors introduced its first commercially available 40 Gb Dual-Depletion InGaAs/InP p-i-n Photodiode at the Optical Fiber Conference in Dallas, Texas, in 1997. Since that OFC, we have expanded our pioneering dual-depletion photodiode design for several cutting edge products such as Balanced Photodiodes for 40 Gb, and Ultra-fast photodiodes up to 60 GHz. Today, our 40 Gb product line has evolved to include PIN+TIA optical receivers, with both linear and limiting amplifiers. These receivers work up to 40 Gb from 1064 nm to 1650 nm for single mode applications, and additionally up to 25 Gb for 850 nm multimode applications. For 25 Gb data rates, these receivers come with an optional CDR. Additionally, we supply 40 Gb Integrated Balanced Optical Receivers for 40 Gb DPSK/DQPSK systems. For busy test stations or student labs, where users of different experience levels might be handling high value opto-electronics that are easily damaged by mishandling, order your photodiode to be mounted in our Lab Buddy instrument.

  • OPX-LTS - Loss Test Set

    Company: AGIZER

    High quality power meter. InGaAs Photodiode with large sensitive area (1000μm) installed right to the optical adaptor on front panel.ORL Meter and another calibrated power meter (PD coupled to fiber, same port as light source) for bidirectional testing and talk set.

  • PDA-750 - Photodiode Amplifier

    Company: Digital Communication

    The PDA-750 is a low noise, high gain, transimpedance amplifier and current meter that is designed to provide a direct digital readout of the current generated from a photodiode, photomultiplier, or similar current source. It provides for digital entry of detector responsivity in units of Amps/Watt which enables it to be used as a sensitive, high precision optical power meter. It also incorporates a digitally controlled bias source (from -14 to +14 volts) that may be switched to be in series with the detector under test. This permits in-circuit detector biasing as well as easy measurement of detector leakage currents. A serial port is supplied that allows the user to both control the unit and log data.

  • SLS-9400 - Tri-Stimulus Colorimeter

    Company: Gamma Scientific

    The SLS 9400 tri-stimulus colorimeter consists of a color sensor and a handheld display unit. The color sensor utilizes four extremely stable colored glass filters in conjunction with high quality silicon photodiodes. The resulting response of this combination accurately replicates the CIE standard observer (tristimulus) functions. This allows the system’s performance to be independent of the phosphor set under test.

  • 2500INT-SMA - Integrating Sphere with Germanium Detector, 2-inch

    Company: Keithley Instruments

    The Model 2500INT Integrating Sphere is the latest addition to Keithley's growing line of solutions for LIV (light-current-voltage) testing. When connected via a low noise triax cable to the Model 2502 Dual Photodiode Meter included in Keithley's LIV Test System, the integrating sphere allows the system to make direct measurements of optical power with results expressed in watts.

  • FiberPal - Network OTDR

    Company: Radiantech

    The NFO OTDR unit injects the laser pulse into the fiber under test and picks up scattered and reflected optical signals by an avalanche photodiode (APD). The unit accepts remote commands from Internet to control all related timing and data acquisition processes. Maximal three wavelengths are available at the NFO with options on 1310, 1490, 1550, and 1625 nm.

  • Series 100 - Fiber Optic Tap Monitors for OEM

    Company: EigenLight

    EigenLight's Series 100 Optical Tap Power Monitors are used for in-line measurement of power in optical fiber. These GR-468 Telcordia qualified devices are used in 40G and 100G optical transport systems around the world, as well as in specialty lasers, test instruments, and other applications. The Tap Power Monitor's small, hermetic package houses a stable optical tap and PIN photodiode. By utilizing a patented process to scatter light out of the fiber optic core directly onto the integral detector, these devices maintain fiber continuity and avoid lenses or partial reflectors in the optical path. This provides exceptional performance, including the lowest insertion losses among competing technology, virtually no back-reflection, and directionality to >30 dB. Fiber continuity also means reliability for the most demanding power measurement applications. EigenLight's Fiber Optic Tap Monitors offer cost, size, and performance advantages over conventional discrete coupler and photodiode combinations and is available in virtually all single mode fibers, as well as a wide range of PM fiber types.

  • Solar Cells

    Company: Sourcetronic GmbH

    Each photovoltaic installation and each solar module consists of individual solar cells. In these cells, solar energy is converted into electricity. They are made of silicon and work the same way as large area photodiodes which are operated as a power source. These days there are mainly two types of solar cells, which are either monocrystalline or polycrystalline cells. The quality of those cells is specified by their respective efficiency. The efficiency is the ratio of power generated by the cell to the incoming solar radiation. Not only the efficiency but also other characteristics such as failure rate and the performance degradation due to aging are critical. The Sourcetronic solar cells are characterized precisely by these properties and are produced with state of the art technology. To achieve a high quality standard, the production process is monitored constantly. In order to minimize disruption of the cells and prevent the delivery of defective cells, IV and EL-Tests are performed before cell lamination takes place to ensure reliability. The IV test analyzes the performance of the cell with the IV curve. With the EL-Test (electroluminescent) the cell is examined for structural damage. Therefore micro cracks are the most often reason for structural damage.

  • Electrochemical Workstations

    Company: Sciencetech

    The automatic comparison between set value and sensed intensity eliminates the influence of non-linearity, ageing and temperature drift. Furthermore, it allows the direct calibration of the light source in units of intensity (W/m²).The CIMPS package consists of several components, working together in a plug & play application, including software and an overall calibration of the system. An electrochemical workstation IM6 or Zennium acts as a frequency response analyser and as a support unit (potentiostat / galvanostat) for the cell under test. The IM-series workstations are renowned for their high precision, ease of use and comprehensive software. A slave potentiostat, driven by the IM6/Zennium system, controls amplitude and modulation of the light source over a wide range of frequencies.An optical bench carries the housing of the light source with the integrated photo-amplifier and the slide with the photo-electrochemical cell (PECC-1 and PECC-2). A photodiode sensor is mounted near the site of the cell’s light inlet, adjustable in height and angle. Depending on the application, you can chose from different types of light sources.
