IR optical filter reducing the effects of extraneous light can significantly improve contrast, speeding up or improving the accuracy of the machine vision inspection. When there may be short- or long-term changes in ambient lighting, optical filters can also provide assurance that the results obtained by the machine vision system will not be affected. Let's us see IR optical filter of the some information.
IR optical filter vision application developers know that considerable emphasis has been placed on choosing the correct lighting to achieve maximum contrast. While correct lighting can overcome many imaging problems, the wrong lighting can cause even the most sophisticated system to run too slow or give an excessive number of false rejects or false accepts. Compared to lighting hardware, little is understood about the use of filters in machine vision applications and we will attempt to address this important subject in this article.
