Navitar: Precise Eye System
   

precise eye system, designed to provide superior optical performance and high vibration stability over standard c-mount video lenses.Not Your Standard CCTV Lens

There are a growing number of video imaging applications in which a single, constant magnification and a fixed working distance are required. Navitar has responded to this need with our new Precise Eye series of lenses. Precise Eye lenses are designed to provide superior optical performance and high vibration stability over standard C-mount video lenses. They are optically precise and rugged to meet the demanding needs of fixed, high magnification machine vision, metrology, fiber optic, and industrial imaging applications. Precise Eye lenses incorporate Navitar's precision engineering along with quality construction, resulting in images that are sharp, high resolution and optically corrected for remarkable image quality.

 

  • High resolution, diffraction-limited f/4.5 optical quality for high precision measurement and inspection.

  • Long working distance makes lighting and handling easier.

  • Compact size.

  • Coaxial lighting available for shadow free illumination.

  • Compatible with high-magnification infinity corrected objectives (5X, 10X, 20X, 50X).

  • Mechanically stable for the most demanding vibration environments.

  • Modular design for flexibility.

  • Optics attach to any C-mount camera.

  • Short tube length (approx. 4 inches) and small diameter (1.25 inches).

  • Allows for co-axial illumination and/or 3 mm fine focus.

  • High transmission (>70%) over the visible to near IR spectrum.

  • Covers magnification factors of between 0.30X and 7.2X.

  • Working distance ranges from 36 mm to 356 mm.
