KEYENCE's digital microscope achieves a depth of field at least 20 times greater than that of optical microscopes. It provides a perfect representation of even large projections and depressions that are difficult to bring into focus with optical microscopes. Adjusting the focus is quick and easy.

Only a limited part of the target can be brought into focus, while the rest remains out of focus. As a result, observation requires a great deal of time and it is more likely that a minute flaw or foreign object on the target will be overlooked.


		Advantages of the digital microscope

- Adjusting the focus is quick and easy.
- The entire target image is clearly focused, providing exact observation data.

Excellent Optical Design

In addition to depth of field, lens performance is also defined by other factors such as resolution, brightness, observation distance and aberration. KEYENCE's digital microscope lens has been designed to offer an excellent balance of all of these:

Resolution
The high resolution VH-Z500 zoom lens includes a total of 24 lenses. By using a fluorite lens, color aberration is almost ideally compensated for and the lack of curvature around the lens helps to reduce the level of measurement error factors. Moreover, because the resolution and magnification have been increased at the same time, the object can be clearly observed. This lens symbolizes the quality optical techniques employed by Keyence digital microscopes.
