ZEISS T* UV Filter
Description
ZEISS T* UV Filters block the invisible UV components of light from the sky, which can
cause blur, loss of contrast or blue color cast. The correct color reproduction in normal
daylight illumination spectrum remains unchanged. The ZEISS T* UV Filters will reliably
suppress any color cast caused by an unusually high UV radiation in the light, e.g. in high
altitudes (in the mountains), by the sea and in regions with very clean air.
The T* UV Filters featuring the T* anti-reflective coating from ZEISS provide optimal
protection for the front element of your lens. We recommend to use the ZEISS T* UV
Filters at all times for protection purposes.

ZEISS Quality
Using a low quality filter optical effects might appear diminishing the quality of your
picture. Especially fast lenses of long focal lengths need demanding polish quality of the
filter to preserve the image sharpness. The high-quality glass is optically homogeneous
and the surfaces are accurately plane to match perfectly for high-performance lenses.
Filter Coating
All ZEISS T* UV Filters feature the T* anti-reflective coating. Special substances, one by
one, are vaporized with very high energy in a high vacuum, which are then deposited on
the glass surface as coatings with precisely controlled thicknesses to increase the
transmission of visible light and achieve the desired reduction of reflections. The
technology has been constantly improved since it was first applied by Carl Zeiss back in
the 1930s.
Filter Mount
ZEISS T* UV Filters are equipped with standard filter thread mounts with an additional
front thread mount , e.g. to attach the standard lens cap. Due to their slim frame design
they can be used on wide angle lenses, even on a full frame camera body, without
vignetting. ZEISS T* UV Filters provide high-fit accuracy for fast filter change and can be
used on lenses in combination with their dedicated lens shades.
Transmission Curves
ZEISS T* UV Filters show a very steep edge at approximately 410nm so they block UV light
of shorter wavelength completely. UV Filters have a nearly constant transmission within
the range of visible light (between about 410nm and 700nm). So the filter appears
completely clear and does not tamper the hue.
