Precise Eye Fixed Magnification Lens





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.


PreciseEye Body Tubes

The Precise Eye system body tubes are the core component of this fixed optical relay lens system. Body tubes may be configured in a finite conjugate system with fixed working distances or in infinity corrected systems where objectives are utilized for greater magnification. Options include:

PreciseEye Adapter Tubes

An adapter tube is a required component for the complete Precise Eye System.

Adapter tubes are available in magnifications range from 0.5X to 2.0X.

adapter tubes are available in standard and right angle formats

and mount to vary the orientation and optical path of the system.

1-62263 2.0X Non Inverting Right Angle Adapter
1-62214 2.0X Right Angle Adapter
1-61450 2.0X Standard Adapter


PreciseEye Lens Attachment

Lens attachments thread onto the bottom of the zoom system and can

extend the working distance out to 350 mm or pull it in as close as 35

mm. The extending lenses (.75X, .5X, and .25X) decrease the overall

magnification, and increase the field of view. The shortening lenses (1.5X,

and 2.0X) increase the magnification and decrease the field of view. As the

working distance goes from long to short, the “taking NA” of the system

increases, resulting in an increase in resolving power.

Right Angle and Non-Inverting Right Angle attachments are also available
