RZ Lens |
|
| Real Zoom Lens |
The VHX-600 uses the RZ (real zoom) lens, a high-performance lens that can correct chromatic aberration to an ideal value. Through the leading-edge optical design and advanced illumination technology, the VHX-600 can minimize aberration distortion. Furthermore, with the highly-telecentric lens design, the RZ lens can create extremely clear depth composition images and 3D images. By making the best use of the digital focus functions that are the essential feature of the VHX Series, the high-performance RZ lens enables real observation as its name expresses.
The lens unit is comprised of 24 lenses in total, including 13 lenses for the objective section, and 11 lenses for the zoom section. Using a silica lens, the VHX-600 can correct chromatic aberration. |

VH-Z100UR: UNIVERSAL ZOOM LENS [NEW]
|
|
Makes Differential Interference Contrast Observation Possible |
 |
| 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. |
|
|
How can a DIC Prism help with microscope analysis? |
|
| 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. |
|

|
|
Monitoring distance: 85 mm |
|
 |
| With the state-of-the-art optical design and advanced illumination technology, the LW lens has achieved a long monitoring distance of 85 mm with a magnification of up to 500x.
The deep recess in a target can be observed with a sharp image. The wider working space ensures significant improvement in the monitoring efficiency. |
|
10x optical zoom |
|
 |
The wide-range design enables seamless monitoring of targets by capturing from a whole image to a magnified image.
You can change the magnification while keeping the 85 mm monitoring distance, resulting in a great improvement in the work efficiency. |
|

|
 |
The "deep depth of field", which is one of the biggest features of microscopes, has been enhanced further.
A depth of field at least three times deeper compared to conventional models ensures observation of sharp images of targets with uneven surfaces. |

 |
| The VH-Z100 has a depth of field approximately 2-times higher than that of conventional modles. The flare generated by irregular reflection of illumination light has been significantly reduced by precisely examining the curvature of each lens and applying our original lens coating technology. Both high resolution and high depth of field are achieved by adding an optical aperture to the bright, high-contrast lenses. |
