    Which metal is the most transparant to RF?

    I've heard that some metals are more transparent to RF than others. ie: titanium and aluminum block less RF energy than steel and brass. Is there a list or chart that lists the relative transparency of metals to RF?

    How to specify/order aspheric lenses

    I want to order some aspherical lenses to use with focusing the light output from a single LED. I am not familiar with optics and I would like to know how to calculate the needed specifications so I can order from an optics supplier. Is there some sort of formula that I can use?
