The
UWA100 lens from Light & Motion is a professional lens that delivers
an astounding 100* degree field of view with minimal distortion
and 100% full zoom through. The dynamic range and angle of coverage
of the lens is what separates it from the competition. In addition
to the ultra wide angle capability, the full zoom range of the camcorder
is actually improved. High resolution macro images can be recorded
when the subject is only 6 inches from the port vertex in air and
28 inches from the port vertex in water.
Full
Zoom Capability
Objects as close as 6.5 inches in air and 28 inches in water can be
brought into clear focus while operating the camcorder at full aperture
and full tele zoom.
Minimum
Distortion
Distortion in the extreme corners of the image is limited to less
than 4.5%. Thus perceptible distortion is nominal.
High
Resolution
Meticulous assembly of precision optical grade components produces
the highest quality lens. Every component of the optical lens design
undergoes interferometric testing to ensure consistent optical performance.
Air/Water
Use
Constant angular magnification in air and water is a feature of
the UWA100 that allows for above water, below water and over/under
image compositions.
Color
Correction
Low dispersion optical grade glasses are used in an achromatized
optical design to provide excellent color correction at all object
distances and zoom ranges.
Optical
Coatings
All optical surfaces are High Efficiency and Anti Reflection coated.
The external surface is seawater resistant with a hard coat, which
resists scratches and allows for aggressive cleaning to remove residue.
*
Depending upon the distance of the subject from the port vertex
of the lens, the angle of coverage ranges from 180 degrees to 92
degrees. For example, if the lens were to actually contact the subject
(0mm away) the angle of coverage is 180 degrees. At infinity, the
angle of coverage is 92 degrees. For accurate comparison of lenses,
angular field of view should be referenced at the entrance pupil
