LineCam12 The LineCam12 is a digital linescan camera for imaging in the SWIR and visible bands (0.4-1.7μm). It has two digital output formats USB3 Vision and Camera link. The device can even be powered by USB3 in most applications. The LineCam12 utilize a 1024x1 state of the art InGaAs linear array imager on 12.5μm pitch that was built for both machine vision and spectroscopy. LineCAM12-12.5-1.7-T (Spectroscopy applications) LineCAM12-12.5-1.7-M (Machine Vision applications) The LineCam12 also is available in an OEM version stripped of its housing.. This camera can be customized to fit in various user systems. We can also add custom filters to the array. Vision System Design 2017 Innovators Program- Gold Level Winner
1280SciCam This lattice matched InGaAs camera allows for high resolution SWIR and visible imaging 1280x1024 at high frame rates >95fps at full frame size. This small pitch array, 12μm, combined with the high quantum efficiency of the lattice matched InGaAs arrays enables impressive imaging in the SWIR and visible band. The camera has the capability of three setpoints, 25C (no cooling), 0C, 40C (fan cooling) or -60C (water cooled) using a 3 stage TEC integrated in a vacuum package. This advance digital array (PIRT1280A1-12) on board offers 14 bit digital output with low read noise of 3 minutes. Vision System Design 2016 Innovators Program- Gold Level Winner
1024L1 Linear Array The 1024L1 is a 1024x1 state of the art InGaAs linear array imager on 12.5µm pitch that was built for both spectroscopy and machine vision in the Short Wave Infrared Band. The 1024L1-12.5-T is an advanced digital array with the lowest read noise available
PIRT1280A1-12 This lattice matched InGaAs 2D focal plane array (FPA) allows for high resolution SWIR imaging at high frame rates >90fps. This small pitch array, 12μm, combined with the high quantum efficiency of the lattice matched InGaAs arrays enables impressive imaging in the SWIR band. It boasts an on board 14-bit A/D with very low read noise of
