Recently released Goldeye G\/CL-008 XSWIR cameras<\/a><\/strong> with QVGA resolution extended range InGaAs sensors offer two sensitivity options: up to 1.9 \u00b5m or 2.2\u00b5m. <\/p>\n\n\n

The Extended Range (ER) InGaAs sensor technology integrated into the new Goldeye XSWIR models provides high imaging performance beyond 1.7 \u00b5m.<\/em><\/p>\n\n\n\n

The cut-off wavelength can be shifted to higher values by increasing the amount of Indium vs. Gallium in an InGaAs compound. Corresponding sensors can only detect light below the cut-off wavelength. In the Goldeye XSWIR cameras there are four different sensors with VGA and QVGA resolution and cut-off wavelength at 1.9 \u00b5m or 2.2 \u00b5m that provide very high peak quantum efficiencies of > 75%.<\/em><\/p>\n\n\n

In these cameras the sensors are equipped with a dual-stage thermo-electric cooler (TEC2) to cool down the sensor temperature by 60K vs. the housing temperature. Also included are image correction capabilities like Non-Uniformity Correction (NUC) and 5×5 Defect Pixel Correction (DPC) to capture high-quality SWIR images beyond 1.7 \u00b5m.<\/p>\n\n\n\n

Goldeye XSWIR cameras are available with two sensor options. The 1.9\u00b5m version detects light between 1,100nm to 1,900nm and the 2.2 \u00b5m version from 1,200 \u2013 2,200nm.<\/p>\n\n\n

Industrial grade solution for an attractive price:<\/strong> Other sensor technologies available to detect light beyond 1,700 nm based on materials like HgCdTe (MCT), Type-II Superlattice (T2SL), or Colloidal Quantum Dots (CQD) tend to be very expensive. The Goldeye XWIR Extended Range (ER) InGaAs sensors have several advantages including cost-effective sensor cooling via TEC, high quantum efficiencies, and high pixel operability (> 98.5%).<\/p>\n\n\n\n

MCT or T2SL sensor-based SWIR cameras typically require a very strong sensor cooling using Stirling coolers or TEC3+ elements. By comparison the Goldeye XSWIR cameras are available for a comparatively low price.<\/p>\n\n\n\n

The easy integrability and operation of ER InGaAs sensors makes them attractive for industrial applications, including but not limited to:<\/p>\n\n\n\n
