At the same time, the diodes retain the low-noise, low-capacitance, and fast rise and fall times characteristics. To help simplify many design needs, these APDs are also available in Excelitas’ high-performance hybrid preamplifier module type C30659 series, as well as the preamplifier and TE cooler incorporated module type LLAM series. In addition, these APDs are also available with built-in thermo-electric cooler for easier temperature control. The C30954EH long-wavelength enhanced silicon avalanche photodiode (Si APD) provides a 0.8 mm active area diameter in a TO-5 package. The C30955EH long-wavelength enhanced silicon avalanche photodiode (Si APD) provides a 1.5 mm active area diameter in a TO-5 package.

For X-ray or gamma-ray application, these multi-channel detectors offer scintillator-mounting options: BGO, CdWO4 or CsI(TI). BGO (Bismuth Germanate) acts as an ideal absorber: it is widely accepted in high-energy detection applications. CdWO4 (Cadmium Tungstate) exhibits sufficiently high light output, helping improve spectrometry results. CsI (Cesium Iodide) is another high energy absorber, providing adequate resistance against mechanical shock and thermal stress. When coupled to scintillators, these silicon arrays map any medium or high radiation energy over to visible spectrum via scattering effect. Also, their specially designed PCB allows end-to-end connectivity. Multiple arrays can be deployed in situations that call for larger scale assembly.

C30927 Series: Number of Elements 4; Photo Sensitive Diameter 1.5 mm; Responsivity 15-62 A/W; Capacitance 1 pF; NEP 9-16 fW/√Hz; Spectral Noise Current per Element 0.5 pA/√Hz Excelitas’ C30927 family of avalanche photodiode (APD) arrays and quadrants utilize the double-diffused “reach-through“ structure. This structure provides ultra-high sensitivity at 400 nm to 1000 nm. The C30927 quadrant structure has a common avalanche junction, with separation of the quadrants achieved by segmentation of the light entry p+ surface opposite the junction. With this design, there is no dead space between the elements and therefore no loss of response at boresight. The C30927EH-01, -02 and -03 APD arrays and quadrants are optimized for use at wavelengths of 1060, 900, and 800 nm respectively. Each device type will provide high responsivity and excellent performance when operated within about 50 nm of the specified wavelength. The C30985E is a 25-element silicon avalanche photodiode (Si APD) consisting of a double diffused “reach-through” structure. The standard versions of the Excelitas C30737 silicon APD array series are available with 16 or 64 elements and provide high responsivity between 500 nm and 1000nm. The standard versions are available either in a compact surface-mount “top-looking” leadless package (C30737MA) or in a BGA type “top-looking” package (C30737GA). Both packages are ideally suited for high volume, cost-effective applications where a high gain APD is required. The leadless SMD and BGA packaged parts are RoHS-compliant and suitable for reflow soldering. The C30737MH series of LLC SMD packaged EPI APDs has the smallest footprint SMD packages.

These detectors provide additional sensitivity in the 350 to 550 nm region when compared to the regular photovoltaic devices. For visible and near IR applications i.e. spectral response ranges from 350 to 1100 nm, regular photovoltaic devices can be considered. These detectors feature high shunt resistance and low noise and exhibit long term stability. Unbiased operation of these detectors offers stability under wide temperature variations in DC or low-speed applications. For high light levels (>10mW/cm2), the photoconductive series detectors should be considered for better linearity. These blue-enhanced photovoltaic detectors are not designed to be reverse biased! Very slight improvement in response time may be obtained with a slight bias. Applying a reverse bias of more than a few volts (>3 V) will permanently damage the detectors. If faster response times are required, the photoconductive series should be considered. Please refer to the photovoltaic mode (PV) paragraph in the application note “Photodiode Characteristics and Applications” available under “Downloads” for detailed information on electronics set up.

OSI Optoelectronics offers a multitude of standard and custom combinations. Upon request, all detector-filter combinations can be provided with NIST-traceable calibration data specified in terms of A/W, A/lm, A/lux or A/fc. Among many possible custom combinations, following are a few detector-filter combinations available as standard parts: PIN-10AP is a 1 cm2 active area, BNC package detector-filter combination which duplicates the response of the most commonly available optical aid, the human eye. The eye senses both brightness and color, with response varying as a function of the wavelength. This response curve is commonly known as the CIE curve. The AP filters accurately match the CIE curve to within 4% of the area. PIN-555AP has the same optical characteristics as the PIN10-AP, with an additional operational amplifier in the same package. The package and the operational amplifier combination is identical to UDT-555D detector-amplifier combination (Photop™). PIN-005E-550F uses a low cost broad-bandpass filter with peak transmission at 550 nm to mimic the CIE curve for photometric applications. The pass band is similar to the CIE curve, but the actual slope of the spectral response curve is quite different. This device can also be used to block the near IR portion of the spectral range, 700 nm and above. PIN-005D-254F is a 6 mm2 active area, UV-enhanced photodiode-filter combination which utilizes a narrow bandpass filter peaking at 254 nm.

OSI Optoelectronics’ super linear duo-lateral position sensing detectors (PSDs) feature state of the art duo-lateral technology to provide a continuous analog output proportional to the displacement of the centroid of a light spot from the center, on the active area. As continuous position sensors, these detectors are unparalleled, offering position accuracies of 99% over 64% of the sensing area. These accuracies are achieved by duo-lateral technology, manufacturing the detectors with two separate resistive layers, one located on the top and the other at the bottom of the chip. One- or two-dimensional position measurements can be obtained using these sensors. A reverse bias should be applied to these detectors to achieve optimum current linearity at high light levels. The maximum recommended power density incident on the duo-lateral PSDs is 1 mW/cm2. For optimum performance, the incident beam should be perpendicular to the active area, with a spot diameter of less than 1 mm.
