CentriMax™ can be actively focused anywhere from 3000mm to 60mm by using supplemental MX-Series objectives. Once a working distance is chosen, its patented CentriTel® internal focusing system allows for focusing from top to bottom of objects without change in magnification. Unlike InfiniMax™, CentriMax™ does not need physical movement to maintain magnification by a resetting of the focus. Rather, the CentriTel® internal focusing system maintains constant magnification during focal translation. Depth details peel away, yet magnification remains essentially constant. CentriMax™ is perfect for z-sectioning and making measurements from a fixed position. This lens also features a variable iris diaphragm for increased depth of field without altering CentriTel® characteristics. Other accessories include: supplemental adapters (transmitted or coaxial) for use with Achrovid™, Mitutoyo, Edmund, Olympus, or Nikon infinity corrected objectives.
