Product Family Description

TECHSPEC® High Index Ball Lenses provide for a shorter back focal length, simplifying fiber coupling, due to the high index of refraction. Ball lenses are manufactured from a single glass substrate and can either focus or collimate light. The LASFN-35 substrate has an Abbe Number of 29.06, density of 5.41g/cm3, and coefficient of linear expansion of 7.4 microns/°K (-30 to 70°C). TECHSPEC® High Index Ball Lenses are ideal for endoscopy, bar code scanning, ball pre-forms for aspheric lenses, and sensor applications.

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?
