InGaAs photodiode designed for near infrared spectrophotometry

InGaAs photodiode designed for near infrared spectrophotometry
  The InGaAs linear image sensor consisting of 512 pixels with a 25µm pixel pitch has been introduced by Hamamatsu Photonics. The G12230-512WB employs two InGaAs chips of different cut-off wavelengths, giving it a spectral response range of 950 to 2150nm.

MPPCs incorporate through-hole electrodes

MPPCs incorporate through-hole electrodes
The range of Multi-Pixel Photon Counters (MPPC); the S13360-VE series has been introduced by Hamamatsu Photonics. These COB package type MPPCs incorporate through-hole electrodes called TSV (Through-Silicon Via). This process optimises the available space between the sensitive area and the package edge (0.2mm on the four sides), allowing for a four-sided buttable arrangement.

Avalanche photodiodes counts photons

Avalanche photodiodes counts photons
As an attractive alternative to the photomultiplier tube, LASER COMPONENTS is proud to manufacture the SAP500-series. Based on a 'reach-through' structure for excellent quantum efficiency, extremely low noise, low bulk dark current and high gain, these components can be operated in normal linear mode (Reverse Voltage < Breakdown Voltage) at gains of up to 250 or greater or in 'Geiger' mode (Reverse Voltage > Breakdown Voltage) to permit the detection of single photons.

Smallest photodetector for optical data transmission

Smallest photodetector for optical data transmission
Data traffic is growing worldwide. Glass-fibre cables transmit vast amounts of information over long distances at the speed of light. Once they have reached their destination, however, these optical signals have to be converted into electrical signals for subsequent processing. KIT researchers have now developed a novel type of photodetector that needs far less space than conventional ones.

Photodiodes feature 1.75 or 2.8µm peak wavelength

Photodiodes feature 1.75 or 2.8µm peak wavelength
LASER COMPONENTS' Detector Group has announced the introduction of two IR detectors, the IG19 and IA35. The IG19 is an x-InGaAs photodiode with a peak wavelength of 1.75µm, making it suitable for applications that cannot be met spectrally with a regular InGaAs photodiode. The IG19X1000S4i with a 1mm chip diameter in a TO-46 housing is the standard product.

Photoreceiver makes optical alignment easy

Photoreceiver makes optical alignment easy
A photoreceiver which consists of a photodiode followed by a high-end, variable gain transimpedance amplifier has been introduced by LASER COMPONENTS. The OE-300 features relatively large sized detectors, which make optical alignment easy and also ensure a very high coupling efficiency when using the Si models together with the optionally available fibre optic adapters PRA-FC/SMA.

IR emitter & PIN photodiode combine for oximeter detection

IR emitter & PIN photodiode combine for oximeter detection
EVERLIGHT ELECTRONICS has introduced an IR emitting diode in a miniature SMD package and a high speed, high sensitive PIN photodiode. Both measuring 6x4.8x1.1mm for oximeter detector applications, the IRR60-48C/TR8 IR emitter and the PD60-48C/TR8 PIN photodiode feature optimised red and IR wavelengths of 660 and 905nm, respectively.

InGaAs photodioides suit visible laser detection

InGaAs photodioides suit visible laser detection
  Classically, visible laser detection is an application that would only be suited to silicon photodiodes. However, Laser Components UK has announced that, for designers seeking devices with greater temperature stability, its panchromatic InGaAs photodoides come up trumps.
