Edmund Optics has created a family of high performance optical designs (the 2/3” HP Series family) and developed three customized optomechanical solutions targeted for specific applications. These lens sub-families utilize the same optics as the 2/3” HP Series Lenses, providing the same optical performance in a variety of optomechanical solutions to meet your application requirements:

  • 2/3” HP Series: Features locking cam focus and iris adjustment. This is the most adjustable version of these optical designs and is the typical high quality machine vision lens.
  • 2/3” HPi Series: Simplified mechanics featuring fixed apertures with compact housing. Industrial Ruggedization for reduced size, cost, and locked focus.
  • 2/3” HPr Series: Stability ruggedized with all optics glued in place and a locking C-clamp focus ring for reduced pixel shift and improved focus stability.
