Achromatic Lens
Achromatic Lenses are precision optical components composed of two cemented glass elements designed to reduce chromatic aberration and improve imaging performance across a range of wavelengths. By combining crown glass and flint glass with optimized optical designs, Chenyu Optics manufactures achromatic lenses uncoated or with UV AR, VIS AR and NIR AR coatings for imaging, laser and precision optical systems.
Achromatic Lens Overview
Achromatic Lenses are precision optical components composed of two cemented glass elements designed to reduce chromatic aberration and improve imaging performance across a range of wavelengths.
By combining crown glass and flint glass with optimized optical designs, these lenses provide improved color correction and reduced spherical aberration compared with simple single-element lenses. They are widely used in imaging systems, laser applications, microscopy and precision optical instruments.
Chenyu Optics supports custom achromatic lens manufacturing according to customer drawings, including custom glass combination, focal length, dimensions and coating design for prototype and repeat production.
