One-piece lens barrel is the combination of barrel and holder,it includes the chassis that supports the various lens elements and the cosmetic exterior. Plastic mounts, grooves, and moving portions of the lens are critical to the performance of the lens, and are machined to very concrete tolerances. Our one-piece lens barrel is made of plastic.Plastic mounts are less expensive and its weight is lighter. If the barrel is made of engineering plastic, it is produced by a highly efficient and precise method of injection molding. The interior surfaces of the barrel are also coated to protect them and to prevent internal reflection and flare.
