He began his career in 1813 by apprenticing to John Corless. In 1830 he separated from Corless and started his own business, much of the time in partnership with Joseph J. His company Andrew Ross & Co. Made a number of optical instruments including telescopes, however, he became well known for the quality of his achromatic lenses and high-quality microscopes. Ross introduced a number of improvements to compound microscopes, especially due to his collaboration with J. Lister in creating achromatic objectives. Ross' last instrument won first place at the Great Exibition of 1851.

In 1830 he received the Gold Isis Medal from the Society of Arts for his improved dividing astronomical and mathematical instruments and for his circular dividing engine. He received the same medal in 1836 for his improvements in achromatic objectives of microscopes.

In 1841 he received a silver medal from the Society for his invention of the spherometer. He separated from Lister c1842 and moved to 21 Featherstone Buildings, Holborn. Ross was a founding member of the Microscopical Society of London, which later became the Royal Microscopical Society.

Ross made microscopes from 1831 through 1859, after which the company became Ross & Co. Under the direction of his son Thomas. Thomas' company continued making lenses under the "Ross" name until it merged with Barnet Ensign in 1948. In 1975 the company finally lost the "Ross" name when it was absorbed by first Avimo then eventually Thales Optics.
