PERICENTRIC LENSES: 360° SIGHT WITH JUST ONE CAMERA
PERICENTRIC LENSES are an exclusive product by OPTO ENGINEERING developed in order to make it possible a 3D peripheral vision of objects without any aid of mirrors.
By means of a special optical design, with these lenses just one camera is needed to capture the image of both the front surface of an object and its surrounding sides: when the lens looks at a cylindric object both the front surface and the cylinder surface are imaged at the same time.
The name “pericentric” si due to the special path of the rays inside the objective: the aperture pupil is seen from object space as to be moving around the peripheral zone of the front optical group.
MAIN ADVANTAGES:
- Just 1 camera makes the job of 4 or more cameras placed around and over the object
- No image matching, typical of “multi-point” imaging systems, is necessary
- All the orthogonal sides have the same magnification because the object is seen from its top, not from one side
- Space between the object and the lens is left in order to enable the passing of pieces in on line applications
- Almost any kind of illumination source can be integrated

We have A LOT of expertise in peripheric viewing optics (pericentric lenses of any kind, multi-mirror systems, catadioptric systems, ...). Also we developed several kind of optics to 360° inspect inner holes with fiberscopes, pinholes, fish-eyes and special optics.
