UecAlM serire lens centration measuring instrument is mainly used for assembled lens centration analyzing. UecAlM can finish all the MecAlM series work. Specially, the UecAlM can analyze the assembled lens centration with the added high precision Z-axis positioning and automatic controlling. Meanwhile, UecAlM can also measure the lens parameters like EFL, RC，BFL, Parallelism and on-axis MTF. This machine is very useful for lens design, research andassembling.
