+ My Quote

The SWIR1300KMA is a TE-cooled, USB3.0 InGaAs SWIR camera based on Sony’s SenSWIR IMX990 image sensor. This camera can capture images in the visible and invisible (SWIR: Short-Wavelength Infrared) regions of the spectrum. With its 1280 x 1024 x 5μm pixels users can acquire high-resolution VIS & SWIR images using readily-available and cost-effective ½” C-mount optics at up to 132f/sec. The camera operates in Global Shutter mode: all pixels begin and end exposure at the same instant – ideal for imaging fast changes or rapid motion in the Field-of-View.

The compact 1/2″ optical format of this 1.3MPix imager is made possible by its 5μm pixel size, as compared to most SWIR imagers that have much larger pixels.

This camera is based on Sony’s proprietary SenSWIR technology, in which photodiodes are formed on an indium gallium arsenide (InGaAs) compound semiconductor layer and are connected via Cu-Cu connection with the silicon (Si) layer which forms the readout circuit — a design which enables high-sensitivity over a broad range of wavelengths. This breakthrough yields a SWIR image sensor that is compact yet capable of delivering seamless image capture over a broad range of wavelengths covering from the visible to invisible light spectrum in the short-wavelength infrared range (wavelength range: 400nm to 1700nm).

All QE values on this website are the best estimates available from various sources, and not necessarily from the manufacturer of the specific image sensor or from the manufacturer of the cameras in our Product Showcase. They represent the best estimates for the imagers by themselves, with the caveat that glass and other optics in the imaging path can significantly impact the spectral sensitivity of an imaging system.

As described on our Knowledge Base article on this subject, these values exist in a range. Therefore no absolute precision is implied, even when QE values are shown to two decimal places! These values and graphs are intended to be used for reference can be use for making useful comparisons between cameras. They are not intended to be a specification or a performance guarantee.

In applications that require the best achievable optical resolution, it is desirable to use a lens with an optical resolution ≥ 100 lp/mm for an image sensor with a pixel size of 5μm. This will ensure that the optical resolution of the camera & lens combination is Nyquist-limited by the pixel-size of the camera, and not by the quality of the lens.

The table below shows a selection of SWIR lenses that are compatible with this imager: note that other lenses are also available, including a SWIR 18-108mm Zoom lens with a removable close-up lens for “macro” zoom applications. Contact Scientific Imaging for more details.

Notes:
The working distance (WD) is defined as the distance from the object plane to the front of the lens.
The above are theoretical estimates provided for reference, and are not a guarantee of performance. Actual FOVs and optical resolution are best determined by experiment.
The FOVs and smallest resolvable feature sizes are estimated with the object plane placed at the minimum WD of the lens. A similar calculation may be performed for longer WDs. Please contact us for assistance: our specialists can help you identify a lens that meets your FOV requirements at a Working Distance that is convenient for your workflow.
Increasing the WD will result in larger FOVs, and lower optical resolution (an increase in the smallest resolvable feature size).
(*) The system meets Nyquist criteria if the optical resolution at the center of the lens (in lp/mm) is ≥ the pixel-size limited resolution (see above).
(**) The minimum resolvable feature size is estimated based on whether the lens meets the Nyquist criterion. If the Nyquist limit is met, then the resolution of the system is the estimated to be the distance on the sample plane that corresponds to two pixels in the image plane. If not, it is estimated based on the limiting resolution of the lens.
