Description
Features
Plano-Concave Lenses – One flat surface and one inward-curved surface to diverge light; ideal for myopia correction and balancing positive lenses in optical systems.
Double Concave Lenses – Inward-curved on both sides to spread light; used to reduce magnification and control beam diameters.
Manufactured from high-quality glass, quartz, or plastic with precise grinding for superior optical performance.
Available in multiple sizes to meet diverse application needs.
Applications
Microscopy, laser technology, and medical imaging equipment.
Telescopes, microscopes, and other imaging instruments.
Beam expanders, beam reducers, and beam shaping systems.
Benefits
Improves image clarity, sharpness, and focus in optical systems.
Reduces aberrations when combined with positive lenses.
Provides reliable, consistent performance in high-precision applications.
Performance
High optical quality ensured through strict manufacturing standards.
Excellent durability and optical properties across a range of wavelengths.
