How to Choose the Best Line Scanner Cameras
The line scanner cameras makes use of multiple or single cameras to capture images. The object is appealed in the whole lens field of view. The area scanner camera resolution is determined jointly be the camera power and the size of pixels. For line cameras, the resolution is in the vertical direction and depends on the clock rate and the web speed. The line scanner camera makes it easy to correct distortions and lens shades. Calibration data is only required only on one line and correction requires only one dimension. The line cameras require more light since the exposure time usually shorter. As such, line scanners lens require intense sources of light. They are very applicable in different prices such as metal analysis, 3D scanning, food inspection among others.
There are few things that you should consider when looking for line scanner cameras. High scan rate and large high sensitivity pixels are some of the desirable features. The line scanner cameras can be available either in the monochrome or multi-color configurations. A linear sensor with multiple pixels is used for the monochrome line scanners. Linear filter is applied to obtain color image from single line scan images.
There are different reason why you should choose the high resolution line scanner MACHINE. Larger pixel line scanners allow you to scan with less scene light. It gives higher quality images with any light intensity be taking as many photons as possible. This allows you to invest less money in light solutions.
Lager resolution makes it easy to obtain faster scan rates. This is very important especially in an industrious environment where speed in crucial. the larger signals provides higher signal/noise ratios. Image noise can easily distort the image and should be avoided. You can achieve high quality images with high resolution scanners that have photon collection area, large capacity sweep and larger quantum.

You can even minimize the physical dimensions of the vision system. The lens can be moved closer to the inspected object without changing the field of view. The fact that it is not dependent on light conditions, it can capture quality images under any conditions. When the object is moved closer to the field of view, less light is required.
It is to note that the line scanner camera has a higher preference when compared to its price. This is a great investment to your business. If you want to learn which line scanner is suitable for your business, speak to an expert. The best way is to compare the features if the MACHINE VISION LENS to those of the area scanner camera to see which one is the best fit for your business.
