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
handling.
