Large Diameter Achromatic Lenses for High-Performance Optical Systems

Large Diameter Achromatic Lenses are designed for optical systems that require a wide aperture, excellent image quality, and reduced chromatic aberration. Compared with standard singlet lenses, achromatic lenses can bring different wavelengths closer to the same focal point, reducing color fringing and improving image sharpness.

These lenses are commonly made by cementing two optical elements together, usually a positive crown glass lens and a negative flint glass lens. This structure provides better chromatic correction and spherical aberration control, making large diameter achromatic lenses suitable for demanding optical systems.

Realpoo Optics provides custom large diameter achromatic lenses according to customer drawings, samples, optical design files, or application requirements. We can customize diameter, focal length, coating, glass material, edge treatment, and mechanical dimensions.
