Es gibt 1073 uv-pass-filter Anbieter, die hauptsächlich in Asien angesiedelt sind. After conversion your camera will have much higher UV sensitivity and you will no longer need any UV filters in front of the lens making it easier to compose and focus UV photographs. When produced by the sun, UV-C does not penetrate the earth's atmosphere. Short Wave Pass Edge Filters. A digital camera sees more infrared than we do, and all you need to do to capture it, is to block out all the visible (non-infrared) light. Add to compare. And yet, some UV, of some wavelengths, must pass through glass, because there are more expensive products available for blocking 98% or 99+% of UV, for example to protect million-dollar artwork from any fading. Narrow bandpass filter Steep edges, high optical density in the blockband and highest transmission in the passband ensure the best suitability for e.
