Navitar’s newest lens series offers you MORE:

As the industry leader in high quality, high precision zoom lenses, Navitar would like to introduce the next generation of zoom lens technology.  The Resolv4K Lens Series was designed from first order principles to maximize the usage of modern sensors with higher pixel densities. Numerous adapter options allow users to employ a range of sensors from 1/2î through APS formats and beyond.  On the front end of the zoom, intricately designed lens attachments give users the best of both worlds; the low mag end of zoom gives wide fields of view with no sacrifice in MTF or loss of illumination, while the high mag end delivers microscope objective like resolution at extremely long working distances.

In addition, the Resolv4K lens has been designed not only for superior visible wavelength axial color correction, but dramatically increased wavelength focusing ability with Visible through Near Infrared (Vis-NIR) and SWIR options. An all new LED based coaxial light module pairs with the system to ensure evenness of illumination, even in large FOV configurations.

More Wavelengths

The Resolv4K Zoom lens comes in visible, Vis-NIR and SWIR coating options. The visible options produce superior axial color correction to existing zoom lenses.  The Vis-NIR option allows precision surface inspection in the deep blue, while performing sub-surface inspection at 1100nm without refocusing or loss of transmission. Using the SWIR goes even further beneath the surface to see damage and defects, in food and silicon wafer inspection among other applications.

More Field of View

Navitar’s Resolv4K Series offers so much more resolving power that a 400-600% larger field of view is possible when compared to traditional zoom imaging, without any loss of detail.  No need to stitch together multiple images from multiple captures.

More Resolution

Resolv4K’s higher NA, along with its superior aberration correction, gives more precise measurement capabilities than ever.  Even comparing a 4.5X zoom point to a 7X mag system, the exceptional quality of the Resolv4K design delivers superior performance, as shown in the black to white transitions in the edge spread functions below.  System performance holds up all the way to the corner of the sensor, so multiple regions of interest can be set regardless of their location in your FOV. Your edge detection software will notice the difference.

More Throughput

Combining Resolv4K’s large field of view and exceptional lens resolution with modern high pixel density sensors results in faster image capture of a greater area; making it ideal for high speed inspection and precision measurement applications.
