Depth Composition and 3D Display Function
 
 

State-of-the-art digital focus function and all-in-one PC-less software

Because conventional microscopes provide a shallow depth of field, only limited parts of tar gets with uneven surfaces can be brought into focus at one time. With KEYENCE's digital microscope, however, the digital depth composition function provides sharp images with overall focus, even on targets with great depth. So you can view magnified images that exactly represent the actual target conditions.
 
The digital microscope captures partially-focused images by moving the lens up or down. High-quality depth

In addition, the 3D display function precisely represents the height at each part of the target. You can freely rotate 3D images on the screen, and therefore observe the target's three-dimensional structure, which cannot be seen with conventional microscopes. Since the depth composition and 3D display functions are incorporated right into the controller, the Digital Microscope provides an all-in-one, PC-less design that eliminates the need for transferring captured images to a PC.
 

Advantages of the digital microscope

  Depth composition and 3D display functions
 
- Accurate (a): the depth composition provides sharp images with overall focus, even on targets with great depth, so you can view magnified images that exactly represent actual target conditions.
- Accurate (b): the targetfs three-dimensional characteristics can be observed, for detailed study of its projections and depressions.
 

D.F.D. Method

 
For 3D profile measurement, the VHX Series uses KEYENCE's original "D.F.D. (Depth from Defocus) method." This method allow s the user to obtain three-dimensional depth information through analysis of unfocused areas on two-dimensional images. As the VHX Series digital microscope captures images at various heights by moving the lens up or down relative to the target, the degree of focus at that target point changes gradually. Based on correlations between changes in the focus conditions, the VHX Series determines the height of the optimum focus to execute 3D profile measurement. Even if it does not capture a completely focused image, it can still calculate the target height. The D.F.D. method offers highly reliable data that is minimally affected by target surface conditions-a benefit which is not available with conventional 3D image-creating applications.
