1. In the same way , we can design apochromatic photograph objective by different glasses.

2. Optical design of apochromatic objective used wave disparity method in this paper.

3. Apochromatic correction using AD elements. Mostly used on tele primes and zooms.

4. In the same way, we can design the apochromatic photograph objective by different glasses.

5. The Mak-Newtonian design provides large aperture apochromatic performance with exceptional field correction in a compact, affordable package.

6. By chiseling a BOL on a surface of a lens, a apochromatic system is composed, which actualizes the system's apochromatism, as well as revising primary aberration.
