as far as I remmember PC is usually considered to be selected in discussed areas of interest.
Sometimes PC+ABS. Frankly speaking all transparent compounds could be selected, but there is a factor of quality.
Best would be to contact with compund supplier - BASF, Dupont and so forth or check their knwoledge base to select solution best suited to your needs.
Sometimes it is enough to get real sample of such part and send final supplier for replication. you list your requirements at front - color, max. distance that signal from transmitter through this part should be recieved, etc
