Sentech : STC-AF66B
Description
The Sentech STC-AF66B auto focus block camera was designed specifically for low vision magnifier reading systems and industrial applications. This camera features a high resolution CCD (768 x 494), complete “on-camera” low vision processing and multiple outputs including VGA RGB. With the optional dual element close up lens, the STC-AF66B can auto focus through the entire zoom range at a target only 25cm away. This makes it ideal for applications where precision detail is required using auto focus and zoom capabilities with a close target.
