Specifications UV-Cut Blocker
We can supply various uv-cut filters according to your requirements.
UV-Cut Blocker Ultraviolet (UV) filters block ultraviolet radiation, but let visible light through. Because photographic film and digital sensors are sensitive to ultraviolet (which is abundant in skylight) but the human eye is not, such light would, if not filtered out, make photographs look different from the scene that the photographer saw. This causes images of distant mountains to appear hazy. By attaching a filter to remove ultraviolet, photographers can produce pictures that more closely resemble the scene as seen by a human eye.
