Sensors unveils new multifunctional InGaAs camera
One of the applications the SU1024LDH2 is suited to monitoring substrates used in photovoltaics, solar cell/panels, integrated circuits, and many machine vision tasks for sorting and monitoring continuous processes.
Sensors Unlimited, a subsidiary of Goodrich ISR Systems which provides imaging systems utilizing sophisticated InGaAs technology unveils its latest high-speed SWIR, digital line scan camera.
The latest InGaAs camera, with a wavelength response range from over 800 to 1700nm is 1024-pixels with a 25mm pitch. It features a line rate to over 91,900 lines per second. It is claimed to be ideal for spectral-domain optical coherence tomography (SD-OCT) imaging applications used for detailed medical screening and a vast improvement over the conventional 840nm systems.
The 3” x 3” x 2.4” housing features both metric and SAE mounting holes on multiple sides making it very flexible.
The camera provides an integrate-while-read snapshot acquisition and is suited to many diverse applications. These include applications benefiting the compound semiconductor such as boule and wafer inspection and statistical process control and continuous improvement projects.
It can also be used for applications requiring moisture detection, proteins and other molecular vibration absorbance bands in the 800-1700 nm range.
SWIR technology is said to be suitable for both day and night imaging, unlike many of the CMOS and CCD imagers on the market, which are typically only useable in daylight. They are compatible with Thermal Imagers (TI), in that once an object has been detected by TI, it can identified by SWIR imaging.
SWIR images are not in color. This yields one of the tactical advantages of the SWIR, namely, object or individual identification.
Other cameras that work in the shortwave length infrared range are made from materials like HgCdTe and InSb but these are claimed to be prone to increased signal-to-noise ratios and sometimes require mechanical cooling to very low temperatures.
Another benefit of SWIR imaging is the ability to image through glass, making expensive lensing and environmentally hardened housings often unnecessary.
