Because ozone in the stratosphere has a strong absorption effect on ultraviolet light with the band of 200nm-300nm, there is almost no sunlight in this band in the near-Earth atmosphere, so this band is called the “solar blind zone” of solar radiation. GU Optics’s Solar-Blind UV lens has a working band of 240-280nm, and with a focal length of 116mm, it is commonly used in electronics, optics, medical and precision industries.
