The key to the success of machine vision system is to get a picture with good contrast. In addition to the light source, another important component of image contrast enhancement is the machine vision filter used in the image acquisition module, which is used to remove interference light and extract signal light. Ideal filters should separate the unnecessary image information from the target point, improve the contrast test of the target information in the image, and maintain the long-term stability of the light source.
Wendi machine vision filters have been carefully designed and manufactured to meet stringent requirements for machine vision and imaging applications.
Product Advantages
■ High and flat peak transmission – stop wasting expensive light & uniform lighting can be realized;
■Optimal bandwidth – to obtain the greatest ratio of wanted to unwanted light;
■Superior Blocking – to block unwanted light and pass only what you want to see;
■High angle tolerance - to be used in imaging situations with wide viewing angles;
