Superior Depth of Field |

|
| KEYENCE's digital microscope achieves a depth of field at least 20 times greater than that of optical microscopes-so 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. |

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. |

Targets do not Need to Be Disassembled, Cut or Processed |

|
|
| Unlike with optical microscopes, with KEYENCE's digital microscope the target does not always need to be placed on the stage. You can observe the target simply by pointing the lens toward the target point, so even a large target can be observed quickly, and just the way it is. The digital microscope makes possible quick and accurate analyses and observations, helping provide early solutions to problems. It eliminates the need for disassembling, cutting or processing the target, enabling you to observe secular changes at the same point. |
With optical microscopes, the target must be disassembled or cut before it is set on the stage. |

Target can be Observed at any Angle |

|
| Using the multi-viewer system, the digital microscope permits observation at angles of up to 90°with the target resting on the stage. The camera can be rotated 360°around the center of the visual field, permitting observation of the target at all angles. |
To observe the target obliquely, you must tilt it on the stage to an appropriate angle. It takes a great deal of time to observe a target point. |

Integrated Illumination Simplifies Setup |

|
|
| Since the digital microscope incorporates its own integrated illumination, observation can be made simply by pointing the camera at the target. There is no need for preliminary setup. Anyone can reproduce the same image. |
It takes a great deal of time to set up the illumination. Because the target image varies depending on the lighting, it is difficult to obtain the same image every time. |

Images and Text Data can be Saved in the Digital Microscope |

|
| The controller incorporates a 160 GB hard disk drive which can store 575,000 compressed images. You can enter a title, subtitle, operator's name and comments for each image and then store that reference information together with the images. |
To arrange captured images, the images must first be saved on media and then loaded into a PC. To save shooting conditions or reference data, you must paste images into document creation software and manually enter the conditions and data. |

|
| Magnified images can be projected onto a large monitor, so several people can observe and discuss the target images simultaneously. With this method, urgent analysis by, and discussion among, many observers is greatly facilitated. In addition, inexperienced workers can improve their skills by observing targets along with experienced workers. |
Only one person can view a live image, which means that a great deal of time is required for information sharing. Speedy discussion is not possible, since the target must be observed one person at a time. |
