As an imaging engineer or a procurement manager, you’ve likely seen this heartbreaking scenario: You spend your entire hardware budget on a high-spec 5-megapixel sensor, only to pair it with a mismatched lens and end up with footage that looks like a watercolor painting after a rainy day. You ask your engineers, "Where’s the detail? The specifications said 5 million pixels!" The answer often boils down to a technical metric that isn't as sexy as "megapixel count" or "aperture size," but is arguably just as critical: Chief Ray Angle (CRA). If you are dealing with high-resolution sensors, and your CRA isn't under control, your megapixels are being wasted. Here is the plain-English explanation of why CRA matters for 5MP imaging, and how a precision-engineered lens like our PL057 provides the ultimate solution.

In November 2023, the production of various types of lenses (security monitoring, car mounted lenses, starry lenses, etc.) at the direct factory of Shanghai Boshi exceeded 5.5 million. In December, to meet the order demand, new equipment was added and preparations were made in advance for production next year.

The M12 fisheye lens is a compact optical solution designed to capture extremely wide fields of view with strong distortion characteristics that are often used creatively or functionally in machine vision, surveillance, robotics, and automotive imaging systems. This article explores how the M12 fisheye lens works, its key advantages, application scenarios, and selection guidelines to help users solve common imaging challenges such as narrow viewing angles, blind spots, and low spatial coverage. It also highlights how BOSHI delivers optimized lens solutions for industrial and commercial imaging systems.

An ‌endoscope lens‌ is a tubular device equipped with a light that can be inserted into the human body through natural orifices or surgical incisions to observe and diagnose the condition of internal organs and tissues.
