Plano-Concave Cylindrical Lens, UVFS, AR Coating T4: 1050-1700 nm OLYE100214-T4
JCOPTIX plano-concave cylindrical lenses are aspheric optics that shape beams in one dimension to change spot size. A flat face and concave cylindrical face provide negative focal length; orienting the concave face toward the source during divergence reduces spherical and chromatic aberration. UV fused silica offers high UV transmission and low thermal expansion. JCOPTIX uncoated plano-concave UVFS cylindrical lenses are made from UVFS for sanitary equipment, semiconductor component manufacturing, and other applications. JCOPTIX offers lenses in materials including N-BK7 and UV fused silica. Each can be uncoated for broad bandwidth and high damage threshold or antireflection-coated. Four UVFS coating bands are available: 245-400 nm, 350-700 nm, 650-1100 nm, and 1050-1700 nm. Custom sizes, materials, focal lengths, and coatings meet different applications.
