    Product features:

    The wide UV bandpass filter is designed to effectively let the UV light through and block the light up to 2000nm.
    The U-340 coloured glass is used as the substrate and coated with an interference film to achieve these properties. This special filter provides both low waviness in the passband and stable suppression of the red wavelength range.
