Plano-Convex Lenses is a spherical lenses with one flat surface and one convex surface with a positive focal length. The PCX lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. These optic lenses are ideal for all-purpose focusing elements.

CLZ Optical Co., Ltd. manufacturing UV Grade Fused Silica plano-convex lenses with high performance. Our plano-convex lenses are assure the surface accuracy with ZYGO Verifire Interferometer - 4". The lenses are precision manufactured using UV grade synthetic fused silica. We can provide coatings with antireflective coated on both faces with multilayer AR for 248-400nm use. However UV grade fused silica can be used efficiently at 185nm transmitting over 85%.
