BALL AND DRUM LENSES
Tech Spec Ball Lenses are designed to improve coupling between
fibers, emitters and detectors. Higher refractor length reduces
back focal length, allowing users to build systems with tight
space requirements. Ball lenses can be used for fiber coupling,
endoscopy, bar-code scanning and sensor applications, or as
a pre-form for aspheric lenses. They are available from 1
to 8 mm in diameter, with tolerances of +0/-3µm, 40-20
surface quality and 2µm spherocity. The lens is made
from Ohara's 2LAH79 glass, with a refractive index of 2.0
and Abbe Number of 28.3. Drum lenses are ball lenses that
have been ground down axially; they have the same optical
surface but provide a cylindrical mounting surface to ease

WIDE SUPER-ZOOM HR LENS
The 12 x 5.3 wide super zoom HR lens features Assisted Internal
Focus (AIF) technology and precision crafted glass with an
electron beam coating. The deliver increased resolution with
minimal flair and ghosting, producing images with enhanced
contrast and accurate color reproduction. The HR Series lenses
are fully compatible with 2/3-inch digital 16/9 format cameras.
The 12 x 5.3 AIFoHR wide super zoom combines F5.3 wide-angle
capability with a 12x zoom range of F5.3 F64mm. This zoom
range can be extended to F128mm with a standard 2x range extender.
