Raptor Photonics, a global leader in the design and manufacture of high performance digital cameras, has released a new application note.

More astronomers re looking into the SWIR bands these days. German researcher, Dr. Sebastian Voltmer, has been looking at the inner planet Venus as a Ring next to the sun and how the crescent is getting bigger. He investigated slight irregularities in the atmospheric layers.

The challenge was to reveal the ground structures of Venus in NIR. For surface observations (night side) through the clouds of Venus require a spectral window around 1000nm. Observations at wavelengths beyond 1.0 micron are very interesting to observe the lower clouds of Venus through the infrared radiation that escapes from the planet through holes of lower cloud content at an altitude of about 50 km above the surface.

Dr. Voltmer said, “In my previous images of Venus from May 2020 I only used planetary CCD cameras with NIR sensitivity. It was hard to get any signal of Venus’s surface. But with the cooled Ninox 640 II SWIR Camera, I was able to reveal the surface and the lower clouds in one image.
