Product Catalog: Geltech Aspheric Lenses

Although it has been known for centuries that spherical geometry is not optimal for refracting light, the expense of fabricating nonspherical (aspheric) surfaces has inhibited their use. With the breakthrough of LightPath's® glass molding technology, this optimal lens geometry has become a reality.

Molded lenses are used in a variety of photonic products: barcode scanners, laser diode to fiber couplings, optical data storage, and medical lasers, to name a few. In many of these applications, the material of choice is optical glass because of its durability and performance stability over a wide environmental range. High power transmittance is also an added advantage.
