    Injection molded thick flexible foam frisbie

    Have been asked by a customer to mold a 3/4 inch thick 9 inch dia flexible disk with a hole in the center. Understand that it fits on the arm to help swimmers float. Would like some idea of what materials would be best to make this happen. Thanks Bergg

    filter out all but UV light

    Thanks for the reply. My understanding is that a Si responds to light in the blue and UV range. So was wondering if I could filter out the other wavelengths of light that did not have enough energy to cause the electrons to move. Probably too much to ask but !!!!
