    Wavelength Control in Machine Vision: Why Filters Matter
    In machine vision, optical filters aren’t just add-ons, they’re essential tools for image accuracy. By carefully controlling which wavelengths pass through (and which don't), filters help maximize contrast, enhance color accuracy, highlight critical details and block ambient light that can compromise results.

    Machine Vision Filters: The MidOpt® Difference
    Optical filters are essential for achieving reliable, high-quality results in machine vision applications. They don’t just block or pass light – they enhance system performance by increasing contrast, improving color accuracy, reducing glare and isolating specific wavelengths. But not all filters are created equal.

    Choosing the Right Machine Vision Lens for Your Sensor Size
    When building a machine vision or surveillance setup, the sensor size of the camera is a foundational choice. But its full value isn’t realized unless its paired with the right lens. The wrong lens can waste resolution, ruin field of view or degrade image quality. Here’s how to ensure the lens matches the sensor – and optimizes the system.

    Lenses: Understanding Focal Length and What It Means for Field of View
    In industrial imaging, lenses are fundamental components that shape how the camera captures the world. Among the many lens parameters, focal length plays a pivotal role in determining what and how much we see. Understanding focal length and its effect on the field of view (FOV) is essential for selecting the right lens for your application.
