Hamamatsu Photonics has introduced a back-illuminated 16-channel photodiode array (PDA), designed for use in X-ray non- destructive testing applications. The S11299 uses flip-chip technology that allows the PDA to receive scintillation light from the back side of the array. This flip-chip approach reduces the need for gold bond wires and junction layers on the light input side, vastly reducing the risk of wire bond damage during scintillator mounting. The S11299 uses a new, slender board design, with a vertical height of just 10.2mm. This allows for long and narrow arrays to be constructed. Additionally,


The pigtailing technology allows us to couple almost any combination of detector to any fibre.


There are significant advantages to fibre coupling in applications where having the detector close to the area of measurement is not ideal, such as medical,

analytical, and photon counting measurements where the detector can be optically shielded by an opaque fibre jacket. Laser Components offers its SAP-series Geiger-mode APDs and its low noise IAG InGaAs APSs as standard, which both exceed the requirements of the Telcordia GR-468 standard. Custom APD specifications can be developed. www.lasercomponents.co.uk


the detector is suitable for dual energy imaging, by combining two arrays with differing scintillator thicknesses in a vertical structure. The existing S11212 series is ideal for this and various configurations can be designed to match any application requirement. The S11299 series shows a large improvement in uniformity compared to the popular conventional S5668 array that has been in production for many years. The design also makes the new series highly reliable, by reducing the risk of bond wire damage. This series of PDAs is set to


make a large improvement to X-ray non-destructive testing and security applications especially baggage scanning. www.hamamatsu.com


Laser Components now manufactures avalanche photodiodes with fibre pigtails, achieving coupling efficiencies of almost 100 per cent using the company’s semi-automatic assembly unit with alignment accuracies to within a few microns.

OSI Laser Diode has introduced the latest detector in its avalanche photodiode (APD) family, the LAPD 1550-30R. The low-noise, high- sensitivity, 30µm indium gallium arsenide (InGaAs) mesa structure joins the company’s 75 and 200µm APD series. The high speed LAPD 1550-30R operates at 3.5GHz and features a broad voltage breakdown curve of 30V (minimum) to 40V (maximum) with a typical response of 37V.


Ideal for applications in range-


finding, optical time-domain reflectometers (OTDRs), and high-sensitivity line receivers, the detector is housed in a hermetically-sealed three-pin, TO46 package with a lens cap. The APD module is RoHS compliant and operates from 1,260nm to 1,650nm, with a typical operational wavelength at 1,550nm. The operating temperature ranges from -40°C to 85°C. www.laserdiode.com
