Sample Images

Sensor: 1/3" Aptina MT9V024

In the below image the sugar cube is 35mm from the lens. This is the minimum distance at which the entire cube remains in focus.

The sugar cube measures 16mm x 14mm.

The coin was  at a distance of approx. 23mm.

In this next image the coin was at a distance of 156mm.

In these sample images the sensor used was a 1/4" Sony ICX618. The first image is focused at a distance of 8mm from the lens and the second at 11mm. This lens has a small f number of f1.8 creating a narrow depth of field.
