cameras, for instance, are very effective for separating foreign materials from good product of the same colour.
It is expected that the cost of IR detectors will drastically reduce during the forecast period of 2014-2019, mainly due to product developments and application of product technologies such as MCT and InGaAs
in wider spectral ranges, beyond 8um.
technology can identify the difference, based on chemical properties.
Originally developed for space-based earth observation programs and adapted for military use, InGaAs
cameras detect energies in the SWIR (shortwave infrared spectrum).
Sharp has now succeeded in forming an InGaAs
layer with high crystallinity by using its proprietary technology for forming layers.
Goodrich has pioneered the design and production of shortwave infrared cameras and systems using advanced InGaAs
imaging technology for industrial, commercial, military, agricultural and biomedical markets.
Both models are equipped with three detectors, including a photomultiplier tube for the UV-Vis region, and InGaAs
and PbS detectors for the NIR region.
Sensors Unlimited purchased certain assets of Finisar's Sensors Unlmited subsidiary, which makes InGaAs
photodiode arrays and cameras for industrial spectroscopy, and assumed its name, for $6.
InP overcomes the strain induced performance limitation since it is lattice matched with 53 percent mole fraction InGaAs
Although there is a great deal of ongoing research work in more exotic transistor technologies - such as InGaAs
on InP HEMT, low-temperature AlGaAs on InGaAs
tunneling electron devices and even silicon-on-saphire - currently the most practical semiconductor technologies for microwave applications are silicon bipolar and GaAs-based FET.
Other features include a wide spectral range fromm visible light through NIR in reflectance, transmittance and transflectance modes; high energy throughput, and a wide dynamic range for analysis; and the availability of InGaAs
detector technology for optimum performance in the 800-1700 nm spectral range.
The velocity of electrons is much greater in InGaAs
than in GaAs or AlGaAs.
