Universal Zoom Lens VH-Z100UR / Z100UW / Z100UT

Bright-/dark-field, polarization, transmission and DIC observation can be performed with this lens. DIC observation makes it possible to clearly visualize surface topography of low-contrast and transparent objects.

Feature 1

See sub-micron height changes on a surface

Visualizing surface irregularities that are difficult
to see with standard brightfield observation

By using a high-contrast DIC prism to split the optical axis in two and causing interference with reflected light,
this lens allows for viewing of targets with small changes in surface height.
Clearly view scratches in metal and glass, unevenness of films, and other irregularities.

What is differential interference observation?

The built-in DIC prism splits the optical axis in two, and the light reflected back from the target is superimposed.
The differences that arise from the projections and depressions on the surface are then expressed as contrast.
This makes is easy to see small height changes in a surface,
including those on transparent objects - tasks that are not normally possible with conventional lenses.
