High-resolution real-time zoom lensVH-Z500R / Z500W / Z500T

Thanks to a premium fluorite lens, this real-time zoom lens is able to correct colour aberration. With a total of 24 elements—13 elements in 8 groups for the objective section and 11 elements in 9 groups for the zoom section—optimally combined in an advanced optical design, this lens makes it possible to reduce aberration distortion as much as possible. This high-resolution zoom lens brings together engineering technology elements from throughout KEYENCE.

Feature 1

0.82 numerical aperture (N.A.) with a monitoring distance of 4.4 mm

Featuring 24 high-quality lens elements with advanced polishing technology, this lens significantly helps reduce optical aberration.
In addition, the use of a large-diameter spherical lens allows for a monitoring distance of just 4.4 mm.
Combining both resolution and usability, this lens can be used in a variety of situations.

  • Hard disk drive head, 1500×
  • CCD, 2000×

Feature 2

10× optical zoom offering 500× to 5000× observation magnification

The development of this high-resolution lens with minimal optical aberration makes it possible to achieve a 10× zoom area with
no difficulties. Captured images offer high definition with minor image distortion throughout the entire zoom range.
