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.
New and improved models are now available, providing the ease-of-use of an upgraded focusing mechanism (PCHI MF) and the flexibility of an immediate focusing thanks to the integration of liquid lens technology into the lens’ optical design (PCHI AF).
KEY ADVANTAGES
- 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 - Very high field depth
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 - New focusing ring version available
Manually adjusting the focus is never been easier! - New integration with liquid lens technology
PCHI AF allows for an extremely fast and repeatable change in focus
