Sample Images

Sensor: 1/3" Aptina MT9V024

In the below image, the sugar cube is 115mm from the lens and shows a horizontal field of view of 128mm.

The sugar cube measures 16mm x 14mm.


In this sample image, the penny (d=20.3mm) was at a distance of 20cm from the lens. This is a telecentric lens which means it has a reduced field of view which means the image has minimal distortion.


In these sample images, the sensor used was a 1/4" Sony ICX618. The first image is focused at a distance of 9mm from the lens and the second at 12mm. This lens has a small F Number of F3.0 creating a narrow depth of field.



The image below is taken with an IMX250 sensor which is a 2/3" format. At the full sensor resolution of 2448 x 2048 pixels (5mp), there is a small amount of vignetting noticeable in the corners.

The distance is just 5mm from the coin to the lens glass, demonstrating the macro properties of this lens. The blurring is caused by a combination of a narrow depth of field and a not-very-horizontal image plane.
