- A cemented lens composed of two lenses with different refractive indices and dispersions;
- Wavelength range of anti-reflection film: 400-1100nm;
- Through optimized lens design, the focal length remains almost unchanged across the entire visible spectrum;
- In addition to chromatic aberration, spherical aberration is also well corrected, making it very suitable as a collimating lens for lasers;
- In addition to chromatic aberration of on-axis object points, off-axis coma or astigmatism are also well corrected. It is usually used in objective lens systems, imaging systems, laser measurement systems, or as a collimating lens in laser experiments.

Technical Description
An achromatic doublet lens is a cemented lens composed of two lenses with different refractive indices and dispersions. Compared with a spherical single lens, it can correct chromatic aberration and spherical aberration to a large extent. Compared with a single lens, the achromatic lens can form a smaller light spot. It is usually used in objective lens systems, imaging systems, laser measurement systems, or as a collimating lens in laser experiments. (Chromatic aberration, also known as edge dispersion, is a phenomenon that occurs in the optical path due to the differences in the dispersion coefficient and refractive index of the specific glass material used, as well as the different characteristics of various wavelength rays passing through the glass.)
