VH-Z100UR: Universal Zoom Lens [NEW]

Differential interference contrast observation

In Differential Interference Contrast (DIC) observation, a DIC prism is inserted into the lens, splitting the light path in two. The light reflected from the target by these two beams is then recombined, enabling the optical path difference caused by irregularities on the surface of the target to be expressed as contrast. DIC makes it possible to view minute irregularities and transparent targets - objects that cannot be observed using conventional lenses - with good contrast.

Crystal clear observation of irregularities that cannot be seen with bright field observation

Splitting the light path in two using a high-contrast DIC prism, and filtering the reflected light, allows minute irregularities on the target to be observed. This gives clear images of scratches on glass or metal, and warping in film and other targets.

Height differences are indicated in color

When a λ plate is combined with DIC observation to project polarized light onto the target, the reflected light undergoes a phase change which causes height differences to appear as changes in color. This provides the observer with a visual representation of minute irregularities on the target.

Best Resolution in its Class

KEYENCE has combined its knowledge gained from years of experience in the microscope field with its optical technology to give the VH-Z100UR the best resolution in its class. This lens works in conjunction with the VHX CCD to allow microscope imaging to reach its full resolution potential.

10x Optical Zoom, Wide Range Magnification from 100x to 1000x

The VH-Z100UR inherits the VH-Z100R's observation distance of 25 mm with 100x to 1000x magnification. It provides high-precision observation in both bright and dark fields across a wide magnification range. It also supports a variety of applications including polarization and differential interference contrast.
