Embedded hyperlinks in a thesis or research paper. The only way the B+W 403 could be used on its own to create a purely ultraviolet image is in a controlled environment with no infrared light present, or to use it with UV film with no IR sensitivity, AKA how it was initially designed to be used. All returns must be pre-approved by Kolari before items are sent back. Sandwich-type filters Despite the fact that digital imaging sensors are nowhere near as sensitive to UV radiation as film, the protective properties of a UV filter on your lens are still quite justified. Impurities in the glass and variations in the manufacturing process determine the overall degree of optical clarity the finished product will possess, and will affect the filters ability to transmit the most light and maintain optimal sharpness while reducing chromatic aberrations. These characteristics are all very strong indicators of whether or not an image is composed of purely UV light or if it is contaminated with other, undesired wavelengths. What are your thoughts? Its worth noting that ordinary window glass does a decent job of blocking ultraviolet radiation, which is why aside from possibly schvitzing from the heat, you cant get a sunburn sitting next to a sun-drenched window.
