The PCHI series expands with the new PCHI3M models designed for sensors up to 1.1" (17.5 mm diagonal). These new optics offer high image resolution, ideal for capturing more details such as small impurities in bottles or caps, or manufacturing defects/residues inside threaded holes in automotive components.

The new PCHI3M models are available with either manual focusing (adjustment via gear) or with new liquid lens technology that enables automatic focusing of samples of different shapes and sizes*.

* It is necessary to adjust the working distance.

PCHI optics have been developed 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.

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 depth of field
  Objects featuring different shapes and dimensions can be imaged by the same lens
• Integration with liquid lens technology
  PCHI AF allows for an extremely fast and repeatable change in focus
