2.4mm Diameter x 3.0mm Length NIR I Coated, N-BK7 Drum Lens

Product Details Easier to Mount and Handle Than Standard Ball Lenses Drum lenses are glass spheres, ground down axially to provide a mounting surface. The ground circumference D simplifies handling issues typically associated with ball lenses. Ideal for optical transmission in fiber communications. Type B Drum lenses have a polished plano-surface for direct fiber contact and perform as elongated PCX lenses.
