High Index Half-Ball Lenses

×

TECHSPEC® High Index Half-Ball Lenses feature a higher index of refraction compared to our LaSFN9 ball lenses and provides a shorter back focal length, simplifying fiber coupling. These lenses are available in various diameter options, all with S-LAH79 (Ohara) substrate. TECHSPEC® High Index Half-Ball Lenses simplify system integration and are used in various applications such as endoscopy and bar code scanning. Contact us today to discuss custom options.

FAQ

I am trying to determine whether it is possible to use a reversed lens to defocus a collimated beam into a ball lens in order to increase the BFL of the ball lens. What formulas would I need to use to calculate the lens required and its position?
