3-D imaging and measurement of small parts

Micro-PolyView is a 3D, multi-image optics solution designed to measure and inspect objects whose dimensions range from 1 to 10 millimeters such as electronic components, solder paste and micromechanics.

Six different lateral views are provided by an array of mirrors interfaced to a bi-telecentric lens where the top of the object is directly imaged at the center of the field of view.

The lateral views feature exactly the same magnification and the images remain in perfect focus even when the object is displaced from its nominal position. All the views can be used to precisely measure the dimension of components from different angles.

Micro-PolyView integrates LED illumination with the most appropriate lighting geometry for this optical configuration.

The usual approach
The Micro-Polyview way
The inspection of electronic components, solder paste and micromechanics often requires a sample to be observed from different angles to ensure that all relevant features are imaged. Different perspective views are typically achieved through arrays of cameras or by moving the imaging system around the component: both solutions are complex and expensive Micro-PolyView provides multiple telecentric views of the object in a single image.
Components can be quickly inspected and measured from different perspective angles.
     

What are the key features of Micro-Polyview?
** 360° inspection and measurement of electronic components with single lens system
** Small parts lateral imaging: inspection of objects whose size ranges from 1 to 10 mm
** Measurement capability: the top and the lateral views show the same magnification
** High field depth: part decentering can be tolerated without significant defocusing

Micro-Polyview Optics are easily customizable and versions can be manufactured with:
** a different number of views
** different mirror inclination angles
** asymmetric or special mirror arrays
