Sample Images
This represents the full image size and ratio achieved using a 1/3" Aptina MT9V024 at a distance of approximately 30mm.
In this sample image, the sensor used was a 1/3" Aptina MT9V024. The coin was at a distance of approx. 23mm.
In this sample image, the penny (d=20.3mm) was at a distance of 3cm from the lens.
This is a telecentric lens which minimises distortion by reducing the field of view. Although not a designated macro lens, the lens also focuses very close to the subject.
In these sample images, the sensor used was a 1/4" Sony ICX618. The first image is focused at a distance of 30mm from the lens and the second at 32mm. This lens has a very small F Number of F1.8 creating a narrow depth of field.

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.
