FOLDED ZOOM

Normal digital zoom is processed by S/W, so if you increase the zoom ratio, the image quality decreases, while Optical Zoom pulls the subject as close as possible from the moment you take a picture which guarantee the image quality better than digital zoom.
The optical 5x zoom, which is increasing in demand, is a periscope-type H/W that places lenses left and right, focusing on minimizing the prominent of camera modules, which is called Folded Zoom or Prism.
The prism deflects the light that came through the outer lens so that the image sensor can have a image, and is located in front of the inside lens in the camera module.
Prism is applied for high-end smartphones, and considered as a differentiating factor.

Prism is a core component of the Optical Zoom (5X, 10X) Module, which receives images using low reflection and high internal reflection, and provides clear image quality.
Optrontec's Prism is produced superior quality products compared to the competitors, and combine printing technology to prevent Flare effects with chamfering technology to protect damages in case of any impact.
