Chapter 1 Overview

1.2 Product Outline

This section outlines the VH-8000.

■ Digital HD microscope VH-8000

The VH-8000 is the latest model of a video microscope system implementing magnifying observation with KEYENCE's original digital image processing technology. It provides clear images of targets (resolution: 1000 lines or more) in much the same way as looking into a microscope with the naked eye.

Pen-shaped camera unit featuring a high-definition 2,110,000-pixel CCD The VH-8000 processes approximately six times as much image information as conventional microscopes (compared with conventional KEYENCE models) by featuring fine digital image processing. It accomplishes this without losing portability, a major feature of conventional microscopes. In addition, with KEYENCE's original digital image processing technology, the "observing" function of the VH8000 is further enhanced. For example, the depth composition function enables high-powered three-dimensional observation, and the real-time digital zooming function enables magnification by simply clicking on the desired point on the screen.

The VH-8000 features a SCSI port as standard. A photo-quality digital printout can be obtained in approximately 19 seconds by connecting the VH-8000 with the digital color printer (optional). Moreover, a built-in hard disk is able to instantly save the observation images. It also allows image data communication and file management with supplied editing software by using LAN and USB ports. The improved compatibility with personal computers greatly enhances the "recording" function.

The "measuring" function has greatly improved. The VH-8000 features as standard the nine common measurement functions including "Area measurement" with an assisting function, which automatically extracts the outline of the target. The measurement results can be saved in image file or text file (CSV format) formats, enabling visual inspection and quantitative evaluation by statistical processing.

Furthermore, the VH-8000 features various functions such as the Title/Comment function for entering captions on the screen, as well as the Split screen function for comparative observation. A single VH-8000 offers various functions that were impossible with conventional microscopes.

■ VH Microscope

The VH microscope is a video microscope system that displays magnified observation images on the monitor screen by simply applying a pen-shaped observation unit (CCD camera) onto a target without any disassembling, cutting, or processing. "Observing", "recording", and "measuring" functions are combined in this all-in-one design featuring a super-small CCD camera, a high-intensity halogen lamp, a digital recording device, and an image-processing device.

The VH microscope has the following features:

• A deep depth-of-field enables observation of sharp 3-D images.

• Disassembling, cutting, or processing is unnecessary.

• Many people can observe a target simultaneously.

• The currently observed image can be printed out.

• The currently observed image can be saved.
