PIN photodiode is a kind of photo detector, it can convert optical signals into electrical signals.This technology was invented in the latest of 1950's. There are three regions in this type of diode. There is a p-region an intrinsic region and an n-region. The p-region and n-region are comparatively heavily doped than the p-region and n-region of usual p-n diodes. The width of the intrinsic region should be larger than the space charge width of a normal p-n junction. The PIN photo diode operates with an applied reverse bias voltage and when the reverse bias is applied, the space charge region must cover the intrinsic region completely. Electron hole pairs are generated in the space charge region by photon absorption. The switching speed of frequency response of photo diode is inversely proportional to the life time. The switching speed can be enhanced by a small minority carrier lifetime. For the photo detector applications where the speed of response is important, the depletion region width should be made as large as possible for small minority carrier lifetime as a result the switch speed also increases.

1120 -
Photon Kinetics
The Photon Kinetics 1120 Bare Fiber Aligner makes it possible to reduce test setup time to seconds, thereby reducing overall testing cost. Just strip the fiber, scribe and break it (or use a more precise fiber cleaver, if desired) and then insert the prepared end into the 1120. In an instant, the fiber is coupled to your OTDR or chromatic dispersion test system with low optical loss and low reflectance. The 1120's compact, ergonomic industrial design is well-suited for low to moderate volume fiber and cable testing applications where automated fiber alignment systems are less economical. It is particularly useful as part of an in-process or finished cable test station employing either the 8000i or 8000 OTDR, and the OASYS.net OTDR Automation Software.

8000i -
Photon Kinetics
The 8000i In-Process Test OTDR is the most recent addition to Photon Kinetics' family of innovative solutions for optical fiber cable testing. The 8000i's "cable test optimization" provides the balance of OTDR dynamic range and dead zone performance that's proven to be most effective for accurate characterization of typical fiber cable lengths. Dynamic range has been maximized to reduce measurement time, while resolution has been tuned to ensure that typical cabled fiber defects are detected. The 8000i delivers this optimized measurement capability at a more economical price than our full featured, final QC 8000 OTDR, which makes it a perfect fit for "in-process" testing on ribbonizing or loose tube production lines.

iChrome CLE -
TOPTICA Photonics Inc
TOPTICA's iChrome CLE is a compact laser engine that combines four laser lines in one box. All integrated colors are provided via one polarization-maintaining single-mode fiber. It is available with 405, 488, 561 and 640 nm and more than 20 mW guaranteed output power after the fiber each. The system guarantees a plug & play installation since it includes TOPTICA's proprietary COOLAC automatic alignment technology. This way the system is ready-to-use after one simple button click. 561 nm laser light is generated by TOPTICAs proprietary FDDL technology. Each laser line can be directly modulated up to a frequency of 1 MHz and TOPTICA's "Complete OFF" mechanism guarantees zero photons in the "off"-state.

VL53L1 -
Pure Engineering, llc
The VL53L1 is a state-of-art Time-of-Flight (ToF) laser-ranging miniature sensor. Housed in a miniature and reflowable package, it integrates a SPAD (Single Photon Avalanche Diodes) array, physical infrared filters and optics to achieve the best ranging performance in various ambient lighting conditions, with range of cover glass options.Unlike conventional IR sensors, VL53L1 uses ST’s latest generation direct ToF technology which allows absolute distance measurement whatever the target color and reflectance. It provides accurate ranging up to 4m and can work at fast speed (60Hz), which makes it the fastest miniature ToF sensor on the market.With patented algorithms and ingenious module construction, VL53L1 is also able to detect different objects within the Field-of-View with depth information (histogram) at 60Hz. Scene browsing and multi-zone detection is now possible with VL53L1, thanks to software customizable detection array for quicker “touch-to-focus” or mini depth-map use cases.

Photo Emission Tech., Inc.
QE system provides electronics and software designed for fully automated measurement of external quantum efficiency of solar cells. All systems include probes and a fixed plate sample stage for samples up to 150 mm x 150 mm. The main system components include: custom designed software, measurement electronics, and computer system (Windows 8 operating system). The measurement involves focusing monochromatic light to a spot on the device under test, then accurately measuring the photon flux and current from the test cell. The system utilizes a dual beam configuration with lock-in detection, providing an absolute accuracy of ±3%. The QE system uses a grating monochrometer with silicon/InGaAs/Ge detectors. The system includes automatic order sorting filters and two light sources for monochromatic illumination (a Xenon- arc lamp and a halogen lamp). A single lock-in amplifier is used to measure both the reference detector and test device. The main system comes with all the hardware needed to measure quantum efficiency, a fixed plate sample stage and probes.

EL Imaging Tester -
OAI
EL Testing for Si Solar Cells using High Performance CCD. The determination of luminescence (photo emissions) in solar cells is an important characterization tool. Typical solar cells often have defects which limit the efficiency or lifetime of a cell. Many of these defects are visualized with Luminescence Imaging. By using this technique, the manufacturing process can be optimized to produce better cells. Luminescence Imaging takes advantage of the radiative inter-band recombination of excited charge carriers in solar cells. The emitted photons can be captured with a sensitive CCD camera to obtain an image of the distribution of the radiative recombination in the cell. This distribution is determined by the local excitation level, allowing the detection of electrical losses, thus mapping the diffusion length of minority carriers as the emitted light is low intensity and in the near infra-red range, the CCD camera has a high sensitivity wavelength from 900 to 1100 nm with little thermal noise. This CCD camera provides excellent resolution of 1024 x 1024 pixels with a large 1μm pixel size, multi-megahertz readout speed, and robust USB 2.0 connectivity. The EL CCD Camera is the ultimate high-performance CCD camera for electroluminescence and photoluminescence imaging for Photovoltaic (PV) Cells and Modules. This camera combines low noise electronics and optimal sensitivity in NIR.
