About Buffalo Precision Glass Buffalo Precision Glass (BPG) is based in Batavia, NY. Our manufacturing facility employs skilled and experienced technicians who are supported by our engineering team. We offer a diverse range of production capabilities, focusing on creating curved lenses as well as parabolic, spherical, and elliptical shapes. We continue to utilize much of the technology originally developed by Bausch & Lomb in our curved glass manufacturing. Thanks to our unique vacuum forming equipment and techniques, BPG produces high-quality curves that reduce the need for extra grinding and polishing. Our commitment to advanced technology and equipment, managed by our expert staff, enables us to consistently meet tight specifications while delivering high-quality optics at competitive rates.
