Precise Eye high magnification fixed lens systems provide superior optical performance and high vibration stability compared to standard C-mount video lenses. Precise Eye lenses feature high-resolution, diffraction-limited f/4.5 optical quality for high precision measurement and inspection.

The Precise Eye system body tubes are the core component of this fixed optical relay lens system. All systems are modular and offer the ability to change magnification and working distance by changing the lens attachments or the adapter tubes.

Features Include:

• Long working distance makes lighting and handling easier
• Coaxial lighting available for shadow-free illumination
• Compatible with high-magnification infinity corrected objectives
• Mechanically stable for the most demanding vibration environments
• Modular design for flexibility
• Optics attach to any C-mount camera
• Short tube length (~4 inches/101.6mm) and small diameter (1.25 inches/31.8mm)
• Allows for coaxial illumination and/or 3 mm fine focus
• High transmission (>70%) over the visible to near IR spectrum

System Options Include:

• Non Fine Focus: Perfect for applications where working distance and magnification are fixed. There are no adjustments to worry about after the system is installed.


• Apertures: The aperture function allows the user to adjust the amount of light that flows through the system without adjusting light source intensity. The aperture also can improve depth of field when it is adjusted properly.


• Fine Focus: For applications without separate moving support systems, the Fine Focus body tubes offer focus over a 3 mm (coaxial models only.


• Polarizer: An optical device which converts natural or un-polarized light into polarized light by selective absorption of rays in one direction and passing of rays perpendicular to the polarizing medium. Usually fabricated from stretched plastic sheets with oriented, parallel bi-refringent crystals.


• Coaxial Illumination: Coaxial / on axis illumination is most effective when imaging flat specular surfaces. By integrating the coaxial illumination port, a collimated, diffused and uniform illumination source is integrated into a zoom lens. Coaxial illumination can also be attached parallel to the body of the Precise Eye.
