    16mm Cone Lens

    Developed by BOSHI Optical Technology, the PL‑1645F‑M12 is a compact fixed‑focus cone lens built around 16mm focal length and F4.5 specifications to serve 1/2" sensor imaging hardware. This M12 mount optical assembly adopts full‑glass four‑element structure, delivering 28.3°FOV alongside 8.5mm image circle to match 1/2" sensor and smaller image sensors for space‑limited board‑level camera optics systems. It reaches 95 percent high relative illumination and realizes low distortion performance with TV distortion value of ‑0.25 percent. Its mechanical back focal length measures 3.65 mm and overall total track length hits 28.65 mm for easy embedding into compact camera modules. Created for machine vision and other embedded imaging scenarios from industrial inspection to biometric identification, the lens from BOSHI Optical Technology tightly controls chief ray angle under 8 degrees to restrain vignetting and color shift when cooperating with mainstream CMOS sensors. It balances resolution, miniaturized dimension and cost efficiency, and fits factory automation, logistics barcode reading and medical imaging devices for stable and authentic image output.

  • Why an F1.0 Lens is the Secret to Full-Color Night Surveillance | Shanghai Silk Optical

    Let’s be honest: nobody likes reviewing security footage that looks like a 1920s silent movie shot in a blizzard. For years, the industry standard for low-light surveillance was Infrared (IR) lighting. It illuminated the dark, but it stripped away all the color, leaving you with grainy, black-and-white images where a red getaway car looks exactly like a blue one. Today, the market demands "full-color night vision." But achieving this without blasting a blinding white LED spotlight into the street requires a specific hardware upgrade. It’s not just about a better software algorithm; it’s about physics. To achieve true, noise-free color footage in near-darkness, your camera needs an F1.0 large aperture lens. Here is a deep dive into why F1.0 is the absolute threshold for modern security cameras, and why the materials inside that lens matter just as much as the numbers on the outside.

  • Ruined by Flare and Ghosting? Here Are the Coating Solutions You Need.

    In the world of lens manufacturing, light is our best friend—until it isn't. Whether you are producing lenses for high-end security systems, automotive ADAS, or delicate medical endoscopes, you know the struggle. You design a perfect set of glass elements, only for a rogue beam of light to bounce around inside and create "optical artifacts" that nobody asked for.

  • The 4K Era is Here: Why Your Security System Must Upgrade from 5MP to an 8MP Lens

    Pairing a 4K sensor with a 5MP lens is a costly engineering mistake. Don't bottleneck your hardware. Here is why upgrading to true 8MP optics is mandatory for crisp edge-to-edge security data.

  • 2026 Optical Lens Market White Paper: Beyond Large Apertures and Ultra-HD, Where is the Next Battlefield?

    If you have been reading the spec sheets of security cameras and machine vision systems over the past few years, you’ve likely noticed a trend: it is a brutal, numerical arms race. First, everyone raced to 4K and 8MP resolution. Then, the industry fought the "aperture war," racing from F2.0 down to the massive light-gathering power of F1.0. Today, large apertures and ultra-high definition are no longer futuristic—they are the baseline. They are the price of admission to the market. So, as a procurement manager, system integrator, or product engineer looking at 2026 and beyond, you have to ask: If everyone has an F1.0, 5MP lens, how do I make my product stand out? Where is the next battlefield?
