Applications and Features of Surface Inspection CIS

Applications

Ever struggle with time-consuming, cumbersome equipment adjustment when using a camera?
Using a Mitsubishi Electric CIS, which integrates illuminations lens, sensors, and other parts in one module, enables you to scan wide and flat objects instantly and easily.

Printed documents / label inspection

Surface inspection

Solder printing / circuit board inspection

Dimension inspection

Compared to an optical reduction line camera system, CIS offer smaller distortion in the peripheral area of scanned image and are therefore suitable for length measurement.

Color chart scanning

Color reproduction is the same level as that achieved using standard line cameras.

All forms of surface inspection are supported, from printed material/label/package inspections to length measurement inspections. You can utilize the CIS to find scratches, dirt, part defects, and color defects by connecting it to your software.

Features

1. Easy installation – Compact device (module)

Based on an “all-in-one” concept, the lens, light source and sensor (photodetector) are contained in the same housing, thereby saving you the trouble of individually designing and procuring materials.

The chassis and installation mechanism are simple, minimizing equipment adjustment at the time of installation.

2. One CIS captures a long, wide picture all at once

Three scanning widths are selectable, from 309㎜ to 926㎜, as a module for the application.

To suit each scanning width, the lens, light source and sensor (photodetector) have been integrated into one product, thereby eliminating the hassle of equipment adjustment when using multiple line cameras.

3. Distortion-free & uniform images

The GRIN lens system, which transfers a real, erect image at the same magnification and has same length as each scanning width, is used for Mitsubishi Electric CIS.
Thereby image distortion in the peripheral region of the scanning image is minimized and inspection accuracy is more stable compared to conventional line cameras and optical reduction scanning methods.

4. Clear edge detection

The CIS system captures clearer images than conventional line camera systems. This makes it easy to determine minor defects.

5. Lineup includes both built-in light source and no light source

You can choose from two types of CIS, with built-in illumination or without, to best suit your needs.
CIS with built-in illumination are equipped with our standard white LED array.
The CIS without built-in illumination features a slim housing. The angle can be flexibly adjusted at the time of installation and assembled with the illumination of your choice.

6. Monochrome output model

The new monochrome CIS has been proven complaint and carries the CE marking. It has a camera link connectors concentrated in one spot, and a transfer speed twice as fast as color models!

Easier cable routing is realized by placing the CameraLink® connectors in one place regardless of scanning width. The number of cables can be reduced for low-speed scanning, which helps to reduce peripheral costs.
