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.
Specifications
FAQ's & Further Information
How do I choose the right lens for my application?
Choosing the right lens starts with defining the required field of view (FOV) and working distance, which determine the appropriate focal length. The lens must also be compatible with the camera’s sensor size and provide sufficient optical resolution to match the pixel size and required level of detail.
Application requirements such as minimum feature size, depth of field, and measurement accuracy should be considered, as these influence magnification, aperture, and overall lens performance. For high-precision applications, factors such as distortion and the potential need for telecentric optics must also be evaluated.
In practice, lens selection should be based on the complete imaging system, ensuring the optics, camera, and lighting are all matched to the application requirements.

What are the differences between C-mount and M12 lenses in industrial applications?
C-mount lenses are standardised, mechanically robust, and designed to support larger sensors with higher optical performance, making them suitable for industrial inspection and line scan systems. M12 lenses are compact and cost-effective but are generally limited to smaller sensors and lower precision applications due to reduced optical performance and consistency.
