This article explains why camera lenses must withstand temperature changes. A lens is both an optical and mechanical system: barrels, spacers, adhesives, and optical elements expand and contract at different rates, shifting element spacing and focus. Even if nothing breaks, the point of best focus can move, softening images in outdoor installations. Optical materials also change refractive properties with temperature. Athermalization—designing the system so thermal changes compensate—addresses this. Applications like automotive, surveillance, drones, and industrial vision face repeated cycling, so testing must verify maintained optical performance, not just power-on survival. The right temperature specification depends on the actual environment, not a universal rating.

In October 2025, Silk Optical held a warm and engaging symposium for new employees. Centered on the theme "Together on a New Journey," the meeting facilitated open discussions on onboarding experiences, career development, and company culture. This article highlights the key moments and outcomes of the event, underscoring Silk Optical's people-first approach and its vision to become the most valued enterprise in the optics industry

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.

The technical trajectory of security cameras was not an overnight success but a cross-disciplinary evolution spanning two centuries. Its roots can be traced back to the late 19th century with the first attempts to capture continuous dynamic images. In 1870, English inventor Wordsworth Donisthorpe patented the "kinesigraph," a moving picture camera designed to take a series of photos at set intervals to capture movement. In 1889, Donisthorpe and Louis Le Prince further refined film cameras and projection technology; Le Prince even developed a 16-lens camera, which, while more of an experimental tool at the time, laid the physical foundation for continuous monitoring in specific spaces.

Welcome to 2026. If you are a procurement manager at a manufacturing plant or just a tech-savvy homeowner, you’ve likely noticed that the old "more megapixels is better" logic has officially retired. In the era of AI-driven surveillance, a 4K camera with a tiny sensor is like putting a 4K monitor on a 1990s computer—it looks "sharp" until something actually moves.

This article clarifies that higher megapixels don't guarantee better image quality—optical resolution, determined by lens performance, MTF, and sensor matching, is what truly matters. Edge sharpness and balanced design are critical, especially for AI vision and security applications. An unsuitable lens can waste sensor resolution, causing blur and recognition errors. Boshi Optics emphasizes real optical performance over megapixel counts, focusing on system-level clarity and reliability for cameras in security, automotive, and industrial uses.
