Photo Detector with Integrated Transimpedance Amplifiers
ADN3010-11
Analog Devices optoelectronic amplifiers include a range of germanium photodiodes that, through a proprietary process, have been monolithically integrated with silicon transimpedance amplifiers and limiting amplifiers. This process eliminates the need for bond wires connecting the photodiode to the transimpedance amplifier, which leads to improved performance and greater manufacturing reliability. Our portfolio of products also supports the growing need for optical and electrical interface miniaturization.

Transimpediance Amplifiers
The UDT TRAMP products are transimpedance amplifier (current-to-voltage) instruments that provide a low input impedance to accurately measure the short circuit current of phototransducers such as silicon and germanium photodetectors, vacuum photodiodes and photomultiplier tubes. The range includes the economically priced TRAMP, and for ultra precision and accuracy, the TIA-3000.

Gamma-Ray Analysis Software for HPGe Detectors
GAMMA-W
Gamma-W software performs high-precision analysis of gamma-ray spectra from HPGe detectors, and is ideally combined with the PX5-HPGe and your high-purity germanium detector. It is noted for its accurate and reproducible analysis of small peaks even in the presence of high backgrounds. Gamma-W contains all of the options and algorithms legally required by many jurisdictions for quantitative analysis of HPGe gamma-ray spectra, including detection limit, radioactive decay control, uncertainties, documentation, etc…, and allows users to run samples from within the DPPMCA software.

Germanium Optical Power Head
81623C
The new 81623C optical power head provides a 5 mm detector area and allows flexible placement of the remote optical power meter, which is then connected to the N7749C. The 81623C accepts parallel beams with up to 4 mm diameter, standard SM fiber and MM fiber with max. 100 μm core diameter, NA ≤ 0.3. A wide choice of adapters allows input from popular fiber connector types, bare fibers or open beams. The magnetic D-shaped adapters allow rapid removal and replacement without twisting attached fibers.

High Purity Germanium (HPGe) Radiation Detectors
Semiconductor based photon radiation detectors have been evolving for over half a century, with ORTEC pioneering commercial availability for a majority of that time. Initial offerings were based around lithium-drifted germanium Ge(Li) and lithium-drifted silicon Si(Li). Ge(Li) was later replaced with more advanced, high purity germanium (HPGe) detectors. ORTEC provides a comprehensive suite of HPGe detector solutions covering an extensive range of energies and for a variety of applications.

Cryogenic Temperature Sensors
Germanium
Lake Shore germanium resistance temperature sensors are recognized as “Secondary Standard Thermometers” and have been employed in the measurement of temperature from 0.05 K to 30 K for nearly 40 years. Germanium sensors have a useful temperature range of about two orders of magnitude. The exact range depends upon the doping of the germanium element. Cryogenic temperature sensors with ranges from below 0.05 K to 100 K are available. Between 100 K and 300 K, dR/dT changes sign, and dR/dT above 100 K is very small for all models. Sensor resistance varies from several ohms at its upper useful temperature to several tens of kilohms at its lower temperature.
