Pick Your Goldeye

SWIR cameras (short-wave infrared cameras) detect photons with wavelengths between 900 nm and 2500 nm. Short wave IR light interacts with objects similarly to visible light, as it is reflective; consequently, it exhibits shadows and contrasts in its imagery. As a result, images from SWIR cameras are comparable to visible images in terms of resolution and detail.

Because standard silicon-based sensors are typically sensitive up to 1000 nm only, SWIR cameras require sensors capable of imaging beyond the upper limit of silicon. InGaAs (indium gallium arsenide) sensors are conventionally used for SWIR imaging and cover the 900 nm to 1700 nm spectral range with high quantum efficiency (typically > 70%). Recent improvements to InGaAs sensors enable imaging both visible and SWIR (400 nm to 1700 nm using SenSWIR™ technology from Sony©, for example) or beyond the standard 1.7 µm cut-off with extended range solutions up to 2.2 µm.

As such, 4 categories of Goldeye cameras are available:

• Goldeye VSWIR covering an extended spectral range from 400 to 1700 nm 
• Goldeye SWIR covering a spectral range from 900 to 1700 nm
• Goldeye XSWIR 1.9 covering an extended spectral range from 1100 to 1900 nm 
• Goldeye XSWIR 2.2 covering an extended spectral range from 1300 to 2200 nm
