WebThe refractive index of X-rays is slightly less than 1.0, which means that an X-ray entering a piece of glass from air will be bent away from the normal, unlike a ray of light, which will be bent toward the normal. The equation n = c / v in this case indicates, correctly, that the velocity of X-rays in glass and in other materials is greater ...

Not only does it have the best features of any macro lens for Micro Four Thirds, it is also the sharpest I’ve shot with. It is fully weather sealed to a rating of IP53, adding to it’s versatility.
WebIn simple terms, the higher the refractive index of a lens, the more it will allow thickness reduction when designing its surface geometry, according to the type of refractive error to be corrected and the power. High-index lenses are more complex than mid-index ones, and logically more expensive.
