PCHI Series
Hole Inspection Lenses
PCHI optics have been developed by Opto Engineering® to easily inspect holes, cavities and containers. Unlike common optics or so called “pinhole lenses” which can only image flat fields of view, hole inspection optics are specifically designed to image both the bottom of a hole and its vertical walls.
Thanks to the large view angle (>82°) and innovative optical design, these lenses are compatible with a wide range of object diameters and thicknesses. Hole inspection optics are the perfect solution to inspect a variety of different object shapes such as cylinders, cones, holes, bottles or threaded objects.
Perfect focusing of holed objects: Both the walls and the bottom of a cavity are imaged in high resolution
Cavity inspection from the outside: No need to put an optical probe into the hole
Wide Depth of Field: Objects featuring different shapes and dimensions can be imaged by the same lens
Wide viewing angle: Sample surfaces are acquired by the lens under a convenient perspective to clearly display their features
