| Introduction: | BK7 Plano-Convex Lenses have a positive focal length and near-best-form shape for infnite and finite conjugate applications. Plano-convex lenses focus a collimated beam to the back focus and collimate light from a point source. This lens is designed for telecom band 1510-1650nm use, more for eye-safe lasers. |
