Drum lenses are glass spheres, ground down axially to provide a mounting surface. The ground circumference simplifies handling issues typically associated with ball lenses. Ideal for optical transmission in fiber communications. These UVFS drum lenses are available uncoated or with an antireflection coating optimized in the UV range (250~400nm).
