Re: [APD] Re: Re: ah supply reflectors
There is a lot of variability in the quality of the
matelized mylar films. Some are opaque and highly
reflective, some are more or less transparent and less
reflective. Also, some have a thin metal film on the
surface that eventually flakes, chips, rubs or otherwise
wears off -- this undesireable type usually leaves metallic
smudges on your fingertips when you handle it. Look for
high opacity (hold a piece up to a bright light) and the
metal coating to be sealed in the mylar.
