Achromatic Lens

Achromatic Lens is a compound lens combining two optical materials (e.g., crown and flint glass) to correct chromatic aberration. Through optimized material pairing and curvature design, it significantly reduces dispersion across broad wavelength ranges for enhanced imaging quality.

Chromatic Correction: Minimizes focal length differences between wavelengths (e.g., red/blue light)

Superior Imaging: Reduces both chromatic and spherical aberrations versus single-element lenses

Broadband Performance: Optimized for visible spectrum (400-700nm), with variants for UV/IR

Cemented Design: Typically features a convex-concave pair bonded with optical adhesive
