Achromatic Lenses are made of two concave and convex lenses with different refractive indices and different dispersion rates, which can minimize or eliminate color aberrations.
Overview of Achromatic Lens
ATOPTIK’s achromatic lenses are high-performance optical components designed to reduce chromatic aberration. They are widely used in microscopes, laser systems, optical imaging, spectrometers, and fiber optic communications, where high-precision imaging and beam manipulation are essential. These lenses effectively correct the refractive differences of different wavelengths, resulting in sharp and accurate optical focusing.
How Achromatic Lenses Correct Chromatic Aberration for Sharper Imaging
For better performance, usually the side with the larger radius of curvature (the flat surface) should be turned away from the collimated beam. Color difference comes from the difference in the dispersion and refraction coefficient of different wavelengths of light in the transmission material, so that different wavelengths of light converge at different focal points, double-bonded achromatic lens through the adhesive design of different material lenses, so that the dispersion of the two materials compensation each other, thereby reducing the comprehensive color difference. Achromatic design also helps to improve the image aberration of light sources in a wide wavelength range (composite light sources), improve spherical aberration at a suitable radius of curvature, and improve coma at the same time when the material is selected arbitrarily. Achromatic lenses provide sharper images than optical systems that use a single lens and can form smaller points of light, further improving the optical performance of the lens. Achromatic lenses are suitable for a variety of applications such as fluorescence microscopy, image relaying, detection or spectroscopy.
ATOPTIK's achromatic bonded lens products offer almost constant focal lengths over a wide wavelength range and are available in stock for both positive and negative bonded achromatic lenses and achromatic lenses coated with a variety of anti-reflection films. Anti-reflection film options include VIS, NIR, and SWIR.

Features of Achromatic Lens
Double-Lens Structure
Made by bonding two lenses of different optical materials, typically a positive low-refractive-index crown glass and a negative high-refractive-index flint glass.
Optimized to correct axial chromatic aberration and spherical aberration by aligning the focal points of two wavelengths.
High Transmission Efficiency
Anti-reflection (AR) coatings are applied to minimize light loss and enhance transmission, tailored for different spectral ranges, including ultraviolet (UV), visible (VIS), and near-infrared (NIR).
Various Sizes and Focal Lengths
Available in multiple diameters (ranging from 3 mm to over 50 mm) and focal lengths (from short to long focal lengths) to meet different application requirements.
Customizable in terms of dimensions, materials, and coatings to address specific customer needs.
Superior Optical Imaging Performance
Delivers low chromatic and spherical aberration across a wide spectral range, making it ideal for high-resolution imaging applications.
