Apr 2003
Edmund Optics Inc.Request Info
 
BALL/DRUM LENSES Tech Spec ball lenses with a high index of refraction are available from Edmund Industrial Optics. The lenses can be used to improve coupling between fibers, emitters and detectors and for endoscopy, bar-code scanning and sensor applications. They are available in diameters ranging from 1 to 8 mm with tolerances of +0/-3 µm, 40-20 surface quality and 2-µm sphericity. The company says the higher refractive index enables users to design systems with tight space requirements. Tech Spec Type B drum lenses with a cylindrical mounting surface also are available.
