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, biomedical, fiber optic, and electronic imaging applications.


Precise Eye lenses incorporate Navitar’s precision engineering and quality construction, resulting in images that are sharp, high resolution and optically corrected for remarkable image quality.


 


Precision


Precise Eye lenses provide high resolution and low distortion. The resolution capability (the ability to distinguish minute detail) exceeds that of standard C-mount video lenses and most other competitive micro optics. Precise Eye lenses from Navitar yield image resolution as high as 220 lp/mm.


 


Contrast


The lenses in the Precise Eye series not only resolve finer details, but provide higher contrast levels (the difference between light and dark features) over standard video optics. A lens that produces an image with high contrast will increase the performance of an image processing system.


 


Transmission


Precise Eye lenses are supplied with a high quality, broad band, high efficiency, anti-reflection coating that is optically corrected for the spectral range of 400 nm – 1000 nm which allows each lens to image light from NIR laser diode and NdYAG lasers.


 


Working Distance


Precise Eye lenses offer high magnification at long working distances in order to provide the necessary space required for equipment, specimen handling and lighting.


 


Flexible by Design


The Precise Eye series of lenses is designed on a modular basis. This interchangeable design, combined with a wide selection of available attachments, fixed or 3 mm fine focus, allows you to easily meet your exact needs.


 


Lighting


Fiber optic, LED, co-axial, ring light or other light sources can be selected for specific applications.


 


Distortion


Precise Eye lenses can attain distortion of less than 0.14%.


 


Selecting the Correct Lens


Simply choose the block from the Magnification Matrix that most closely approximates your requirements.


 


Precise Eye Versus Video Lenses


When selecting a lens for high precision applications, it is important to differentiate between standard video lenses and Navitar’s Precise Eye series. Video lenses were originally designed for very low magnification, surveillance applications at working distances of greater than three feet (approximately 1 meter). They were never intended for the high vibration and high magnification environments of the factory floor. The usage of extension tubes and close-up diopter lenses enable standard video lens to work close-up, but this increases distortion and produces loss of resolution.


 


On the other hand, the Precise Eye series is designed to provide high resolution, diffraction-limited performance for high magnification fixed applications. The Navitar Precise Eye series covers magnification factors between 0.30X and 0.22X. The working distance ranges from 13 mm up to 356 mm.


Precise and robust, they are used in machine vision applications requiring a fixed field of view, high magnification and high quality image from a long working distance. They provide a fixed aperture, fixed focus and fixed working distance which ensures robust performance in your demanding environment. Fine focus mechanisms are available on two models.
