  • MidOpt Lens Filters
  • Longpass Filters
  • 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.
  • MAGE WITH CCD/MONOCHROME SENSOR
After: An LP920 Infrared Longpass Filter with 940 LED, resulting in maximum contrast.

    Product Description

    Longpass:

    MidOpt Longpass Filters with StablEDGE® technology are ideal for optimizing infrared imaging. Their unique hybrid design offers exceptional visible blocking. And because of the low sensitivity of CCD/CMOS sensors in longer wavelengths (such as 940nm), it’s important to pass as much light as possible.

    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.

    IMAGE WITH CCD/MONOCHROME SENSOR
    After: An LP920 Infrared Longpass Filter with 940 LED, resulting in maximum contrast.
