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.

EMI/EMP Connectors
-
Filter connector series includes EMI/ EMP/ESD circular, ARINC, D-subminiature and micro-D connector styles. They can be combined with high energy TVS diode technology to achieve lightning and EMP transient protection. Smiths Interconnect's EMI filter connectors use multi-layer ceramic capacitor arrays together with inductive materials to realize robust, high performance low pass filter networks. Where required, transient protection can be combined with EMI /RFI filtering to provide maximum protection. The diodes as well as the EMI filter are packaged separately so the construction of the connector remains modular.

Analog Power Supply
Type NPS-2412
-
National RF's Type NPS-2412 analog power supply was designed to be used in communication equipment where radiated switching inverter noise from conventional “switching type” supplies is not acceptable. The power supply consists of a standard rectified transformer output driving a pair of voltage regulators and filtering networks. The 2412 offers an adjustable voltage output between 2 and 24 volts as well as a fixed voltage output of 12 volts. A maximum of 20 Watts of DC power can be supplied from the unit. As the voltage regulators dissipate power in the regulation process, the power to the load is derated accordingly, dependent on the set voltage to the load. The adjustable regulator is a standard LM-317T integrated circuit device. The fixed regulator is a standard LM 7812 device. Upon customer request, the LM 7812 device may be changed to any voltage rating within the the LM-78xx series of regulators. Contact National RF for this modification if desired.

Besides the described types Inphora can supply detector-filter combinations with parameters matching the customer's special requirement, with different sized housing, without housing. If the application determines the detector's spectral responsivity, we can achieve that with a filter designed exactly to the specifications. CCD cameras with unusual spectral sensitivity functions can be matched with filters to obtain CIE tristimulus response or photopic response. Similarly, photmultiplyers can be matched also with INPHORA filters. When determining parameters for a custom detector-filter combination several details have to be considered:
