Opto Engineering® PCHIL series features hole inspection lenses for the inner inspection of cavities and containers in perfect focus.

Unlike common optics which can only image flat fields of view, these lenses are specifically designed to image both the inner bottom and vertical walls of cavities, cylinders, cones, bottles or threaded objects from the outside.

Thanks to the large angle of view of 82° and the innovative optical design with variable iris and large aperture, these lenses are compatible with a wide range of inspections and different object diameters.

PCHIL series also includes models with integrated Optotune liquid lens technology (-EL models) to provide the flexibility of an immediate and precise remote focusing. This can be extremely useful, for example, for the inspection of complex objects with diameters of various sizes.

PCHIL Series Features Include: High-resolution imaging of holed objects from the outside Simultaneous view of both the side walls and the bottom of cavities Variable iris and large aperture Wide range of object diameters and thicknesses Wide viewing angle Easy and precise manual focusing Liquid lens models for fast and remote autofocus
