    • MidOpt Lens Filters

    MidOpt filters are the premier solution for industrial imaging to ensure flawless control, dependable results and the very best image quality. Every filter is produced with the highest standards in durability, so they can withstand even the harshest environments. Unlike traditional filters, MidOpt filters are designed with a Gaussian transmission curve to allow maximum transmission, emulate the output of the most common LED wavelengths and are less angular dependent.

    Some of the many industries MidOpt serves include:

    › Machine Vision/Factory Automation
    › Security and Surveillance
    › License Plate Recognition/ITS
    › Medical and Life Science
    › Agricultural Inspection
    › Aerial Imaging
    › Motion Analysis
    › Photography and Cinematography

      Neutral Density Filters

      Neutral Density Filters are designed to reduce light intensity neutrally over a specific wavelength range without affecting image color and contrast. They serve as "sunglasses" for your system and can be used with monochrome or color cameras. Neutral...

      Polarizer Filters

      Polarizers are designed to reduce specular glare by passing only the light polarized in the direction perpendicular to the reflected light (glare). In addition, they help improve contrast, increase color saturation and detect imperfections in transparent...

      Shortpass Filters

      Shortpass Filters, also known as "IR-cut" filters, are specially designed to pass a broad spectrum of visible shorter wavelength light, while blocking longer interfering near-infrared wavelengths. Shortpass Filters are typically found over the image...

    • APPLICATIONS: Imaging at 940nm is helpful for moisture detection, as moisture absorbs this wavelength. Without using a filter to block interfering visible wavelengths, the below results cannot be achieved. IMAGE WITH CCD/MONOCHROME SENSOR Before: Water levels with visible light, a 940 LED and no filter, resulting in low contrast.
