Overview
High-Precision Plano-Concave Lenses
These high-precision plano-concave lenses are engineered for demanding optical applications, including beam expansion, light projection, and optical system correction. Featuring one flat (plano) surface and one concave surface, they are designed to diverge light beams and effectively correct for spherical aberrations. Manufactured from high-quality optical glass or fused silica, these lenses ensure minimal distortion and optimal performance in laser systems, imaging instruments, and scientific equipment.
