What is an achromatic doublet lens?

The achromatic doublet lens is made up of a low refractive index crown glass positive lens and a high refractive index flint glass negative lens. A cemented lens composed of two lenses with different refractive index and dispersion can correct chromatic aberration and spherical aberration compared to a spherical single lens. Achromatic doublet lenses are usually used in objective lens systems, imaging systems, laser measurement systems or as collimating lenses in laser experiments.

Achromatic doublet lens product features:

An achromatic doublet is an optical design that combines two single lenses. The two lenses are made of glass with different refractive index and dispersion.

Usually one piece is crown glass and the other is flint glass. Such a combination produces better image quality than a single lens. By optimizing the lens design, the focal length is almost constant throughout the visible spectrum. In addition to chromatic aberration, spherical aberration has also been well corrected, making it very suitable as a laser collimation lens.

The achromatic lenses produced by Horse Optical mainly cover the optical wavelength bands: 240 - 410 nm, 400 - 700 nm, 650 - 1050 nm, 1050 - 1620 nm, 3 - 5 µm and 8 - 12 µm.
