Hi,
Hope someone can help me with this:
Andrews has a GSO quartz diagonal listed as...
Diagonal, 2", dielectric, QUARTZ, 99% reflect., 1/16 wave, 90° $139.00
Whereas Bintel has the same diagonal as
1/12 wave 99% reflectivity $149
I assume that this is the same diagonal - why the difference in wave data, does it matter - is it negligible for visual use? Have Andrews misprinted?
So many questions!!!!
Cheers
Doug
