What is Micro-Polyview?
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.
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
| What type of problems can Micro-Polyview solve? | ||
| Problem |
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. |
How does Micro-Polyview work?
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.
| What can Micro-Polyview do? | ||
 |
||
 |
||
| The suggested working distance ranges from
1.5 to 7.5 mm and the best focusing can be achieved by adjusting the number of spacers in the C-mount interface or by vertically positioning the illuminator+mirror assembly. The image orientation phase can be adjusted by simply rotating the mirror cage or the whole assembly. The top and side views show exactly the same magnification; however the side views appear to be compressed because of the perspective angle. Thanks to telecentric imaging such compression is purely linear and therefore very easy to compensate. |

What if my application requires something
a little different than standard?
Micro-Polyview lenses are easily customizable
and versions can be manufactured with:
**
a different number of views
**
different mirror inclination angles
**
asymmetric or special mirror arrays
