Optical lenses for cameras: explore the engineering behind the image capture. 

Whether you're working on cameras for autonomous robotics, surveillance systems, or other projects, image resolution and sharpness can greatly impact the performance and accuracy of your embedded vision system. That's why understanding how to focus a camera lens is a must-have skill for every robotics engineer or camera hobbyist. In this guide, we provide the techniques, tools, and best practices to help you perfectly focus your camera lens.

An M12 Lens / S-Mount lens is a miniature lens with 12mm diameter threads. Despite the small size, these lenses can outperform DSLR camera lenses.

Ever wondered about the best practices to clean a lens or image sensor? In this article we review the impact of a dirty lens and sensor.

We then discuss best practices and tools to clean optics.

The sensor format size and pixel size of digital camera impacts many performance attributes of camera.

The format type of a digital camera sensor is one of the most confusing and ridiculous concepts in the vision industry.

The chief ray angle (CRA) of a lens and the chief ray of a sensor affect image quality factors such as color shading and vignetting.

The magnitude of impact from CRA mismatch can be.

Even the experts interchangeably use the term "Resolution" when it actually refers to four different technical metrics. We ran across this misunderstanding during a 2018 conversation within the IEEE P2020 working group... We define and explore each in this article

Optical distortion is a third order transverse aberration. The simple explanation is that distortion is the change in magnification (angular resolution) versus image height.

GoPro's marketing team was stuck with "Fisheye" because the first product used a cropped Fisheye lens. The newer GoPros use Wide Angle lenses which are not Fisheye lenses.

A few early users of our lenses are actively involved in the RPi community and mentioned the products in a thread. And many people were curious "well what lens should I use?"

This post explores 12+ Image Quality Metrics and the impact on computer vision. The blog posts and video are from a talk that Max H gave during the Embedded Vision Summit 2022.
