Entocentric lenses have a fixed or variable (zoom lenses) angle of beam spread of the optics to the object.They are used for application areas such as presence and placement checks, pick and place applications, feature inspections, color applications, OCR and code reading. The perspective error makes them unsuitable for survey tasks. Telecentric lenses are special optical lenses characterized by having the entrance or exit pupil at infinity. These are mainly used in survey tasks with high repeatability. Particularly if measurements are to be taken with fluctuating object positions (across the image field in X and Y direction) without perspective distortion.The pericentric objectives are designed for easy inspection of holes, cavities and containers. Unlike conventional optics that can only image flat fields of vision, hole inspection optics are specifically designed to image both the bottom of a cavity and its vertical walls.Thanks to the large viewing angle, these lenses are compatible with a wide range of lens diameters and thicknesses.Hole inspection optics are the perfect solution when inspecting a variety of different object shapes such as cylinders, cones, holes, bottles or threaded inspection objects.
