   Aspheric lenses are known for their optimal performance but the expense of fabricating them has inhibited their use. LightPath’s glass molding technology has enabled the production of high volumes of aspheric optics while still maintaining the highest quality at an affordable price. Because molding is the most consistent and economical way to produce aspheres in large volumes, LightPath has perfected this method to offer the most precise aspheric lens available.
