UV transmitting filters-Glass type These solid UV Transmitting Colour Glass Filters transmit unwanted UV and Visible wavelengths at relatively low cost. The following thickness has been chosen for average transmitting in relation to filter type, however if you require any other wavelength we can make simple calculations in relation to the thickness to achieve your required wavelength.
