Raptor Photonics has published a new application note based on the work of a German researcher, Dr. Sebastian Voltmer, who has been looking at the inner planet Venus as a Ring next to the sun and how the crescent is getting bigger. He was able to capture the very faint radiation beyond 1000 nm of the surface of Venus thanks to the latest state of the art Ninox 640 II VIS-SWIR camera. The cooling to -15°C and lowest readout noise, 18 electrons, gave him much better signal-to-noise-ratio and he was able to reveal the surface and the lower clouds in one mage.
