Using a magnifying glass to focus sunlight on a match is a simple experiment many kids have tried. But during World War II, the Nazis may have taken this idea to an extreme, imagining a powerful weapon called a "solar gun" designed to change the course of the war.
This concept was featured in Life magazine in 1945. According to reports from U.S. military experts at the time, Nazi scientists were working on a terrifying project: a massive lens placed in Earth's orbit. By concentrating sunlight, they claimed it could destroy enemy cities or even boil entire sections of the ocean.
The idea actually originated from Hermann Oberth, a German rocket pioneer and one of the fathers of modern space exploration. In 1923, he first proposed the concept as a way to harness solar energy for peaceful purposes. The project was estimated to cost 3 million marks and take 15 years to complete. Oberth believed in its potential well into the 1950s, though he also acknowledged that such a device could become the ultimate weapon if misused.
Life magazine reported that Allied forces discovered this secret weapon program in 1945, just as they were about to defeat Nazi Germany. The article suggested that the Third Reich had the capability to place a giant mirror 22,236 miles above the Earth, positioned in a geostationary orbit. While no official records confirm the plan, the magazine speculated that it might have been possible to send large mirrored components into space using advanced technology of the time.
The magazine further described how building such a space mirror would require the construction of a space station first. This station would serve as a base for future operations. It would have a large opening, up to 30 feet in diameter, to hold and control follow-up rockets. Once launched, these rockets would connect with the station, extending six cables. As the station rotated, the cables would form a circular frame, and the space mirror would be built around it—showing how science fiction could sometimes blur the line between imagination and reality.
Narrow-band filter specifically refers to the band pass filter with narrow half-peak bandwidth. We use ion source assisted medium hard film production technology, so that the film layer is more firm and the spectral performance is more stable.
