Image resolution is the detail an image holds. Usually, we use “PPI”(pixel per inch) to describe the capability of image resolution, which is a very important technical specification of industrial videoscopes. The higher resolution the industrial videoscope holds, the more accurate diagnosis we can make through observation.
Then what determines the image resolution of industrial videoscope? Basically, four main factors can affect a lot: the lens processing precision, lens coating technology, optical structure design, an optical sensor. Among them, the first two factors relate to the lens part and the latter two factors concerning the supporting core chips and designs. Anyway, all of them have a great effect on the image resolution.
To improve our image resolution, several departments of Yateks has made many efforts. The optical laboratory continues to optimize the optical structure design and instructs the purchasing department to purchase quality CMOS sensors and lens with nearly 100% light transmission ability. In addition, the production department works together with the QC department to control every processing technology of the production.
So far, Yateks has two types of image resolution for industrial endoscopes: 750,000 effective pixels for 8-inch-screen P SERIESand 450,000 effective pixels for 5-inch screen N&W Series.
