Welding Inspection

• Bandpass filters for welding inspection available in 405nm and 650nm wavelengths

 

• FWHM options from 1nm to 300nm, with multiple choices between 8nm to 75nm

 

• Optical density (OD) customization from OD2 to OD6 for desired light attenuation

 

• Designed to minimize ambient light interference while transmitting specific laser wavelengths

 

• Compatible with industrial laser profilers like Keyence LJ-X8000 series for enhanced performance

  • Selecting Filters

    1. Center Wavelength
    The center wavelength should be close the wavelength that your profiler emit.
    (The profiler will usually have a diode laser built in, you can check manufacturer datasheet for reference)

    2. FWHM
    The FWHM can be anything from 10nm to 40nm. Usually 10nm will be sufficient for most of the condition.
