Custom Bi radius cylindrical lens optical glass cylindrical lens

  • Cylindrical Lens
  • BK7 Cylindrical Lens
  • optical glass Cylindrical Lens
  • custom Cylindrical Lens
  • Custom optical glass cylindrical lens with bi-radius (different curvature radii in tangential and sagittal planes) or asymmetrical cylindrical profiles, fabricated from N-BK7, K9, or UV Fused Silica. 

    Unlike standard cylindrical lenses which have a flat sagittal plane (infinite radius), bi-radius cylindrical lenses allow independent control of focusing power in two orthogonal axes

    —useful for astigmatism correction, anamorphic beam tailoring, and custom laser diode collimation where source divergence differs in fast- and slow-axis. Available in plano-convex, plano-concave, meniscus, or toroidal-like cylindrical forms, with edge blackening and AR coating options. 

    Ideal for OEM laser modules, diode bar collimation, and precision imaging systems.
