In some optical application, lens, reflector and other micro-optics components are normally needed to be assembled on optical fibers' end face. We can also process the fiber tip into a kind of lens. At present, MEISU has the first-class optical fiber lens processing technology, and we have independently developed a complete set of optical fiber lens grinding equipment, which can produce various shapes of optical lensed fiber array with low cost and high precision. With the optical fiber lens grinding equipment, MEISU can also test the optical spot, far-field and other parameters of the lens.
