I just visited Tap Plastics and bought a 6 foot long 3/4" OD by 1/16" wall acrylic tube and some 3/4" diameter acrylic half spheres. (less than $6) I plan to use fine sandpaper to frost a surface of the half sphere, probably the flat surface. Then glue that to the end of the tube, and cut off an inch long piece, to be the housing/cosine "filter" for a new PAR sensor. My photodiode will be here late tomorrow.
