JBV's High Quality Optics in Amphibico's Underwater Camera Systems
Amphibico's 2nd Generation, state-of-the-art underwater camera systems feature
full zoom capability, achromatic color correction, and
employ high quality Aspheric glass lenses designed by Dr. Paul Remijan, and
realized by JBV Optical Products Company's expertise. Read about these superior
quality lenses below...
The new aspheric wide angle adapter delivers distortion-free wide angle
images while maintaining zoom capability for high resolution
close-ups. The formation of high quality images in both air and water
provides the convenience of dual air and underwater operation. Angular
magnification is nearly constant in both air and water allowing for
“split images” with minimum shear along the air-water boundary.
COMPATIBILITY
1/3 inch CCD, operating in NTSC or PAL format zoom lens
Advanced optical fabrication technology, special high index glasses and
extensive multi-configuration computer optimization have been used to
design and manufacture the new aspheric AWA-5913 adapter. The lens
produces sharp, distortion free images with vivid colors. Image quality
is consistent over the entire field of view for all object distances and
zoom settings.
DISTORTION FREE
A deep concave aspheric corrector forms a flat image at
the CCD image sensor. Barrel distortion found in non-aspheric
adapters is negligible. Distortion is corrected for both near and
distant objects framed at any zoom setting.
An achromatic doublet fabricated from special high index
glasses provides excellent color correction over the entire field of
view at all magnifications.
USE IN AIR OR WATER
Nearly constant angular magnification in air and
water is achieved by using a highly curved, non-concentric glass dome.
Variation of angular magnification in air versus water ranges from 5%
for near objects at 5.9 mm fl to 13% for distant objects at 59 mm fl.
Split images with as little as 5% shear at the air-water interface are
possible.
FULL ZOOM CAPABILITY
A focus corrector group compensates for the
water-dome or air-dome interface which naturally acts as a negative lens
to limit focusing. Objects as close as 115 mm from the dome vertex ,
(230 mm from dome vertex in water), can be brought into clear focus at
full zoom, 59 mm fl.
HIGH RESOLUTION
High polychromatic MTF is maintained over the entire
field by compensating for the astigmatism introduced by the distortion
correcting aspheric element.
DURABLE OPTICAL COATINGS
All optical surfaces are (H)igh (E)fficiency (B)road (B)and
(A)nti-(R)eflection,
(HEBBAR), coated. The external glass dome surface has a proprietary, seawater
resistant, HEBBAR hard coating which reduces scratches and allows aggressive
cleaning to remove seawater residue.
