The High NA S-Mount Lens: A Closer Look
Understanding S-Mount Lens Basics
At its core, the S-Mount Lens, often referred to as the “M12 lens” due to its M12X0.5 thread, is a miniature marvel. Its compact size belies its powerful capabilities, making it a popular choice for PCB (Printed Circuit Board) cameras, where space is at a premium. The lens can be directly threaded into the M12 mount of the camera, earning it the nickname “board lens.” This seamless integration simplifies the assembly process and enhances the overall performance of the imaging system.
High NA: The Key to Superior Performance
The term “High NA” stands for High Numerical Aperture, a critical parameter that determines the lens’s ability to gather light. A higher NA value translates to a wider cone of light that can enter the lens, resulting in brighter images with enhanced resolution and contrast. For applications requiring utmost clarity and detail, such as machine vision, industrial inspection, and surveillance, the High NA S-Mount Lens proves to be an invaluable asset.
