Achromats are a specialty at LaCroix. Consisting of two or more elements (usually crown and flint glass) bonded together to correct optical aberrations, thousands are manufactured each week for the medical, defense and other markets.

LaCroix manufacturing engineers will work with our production specialist to optimize the manufacturing process utilizing a combination of CNC and conventional manufacturing methods. Special proprietary alignment devices are used to ensure the optical axis of the elements can be maintained to within seconds.
