Various common usage filters were tested with a spectrophotometer*
to determine their transmission with regard to air. The results
are presented as transmission curves according to the wavelength
from 300 to 900 nm. These curves can probably vary slightly from
a filter to the other one.

Violet
filter. Attention, IR is transmitted what can be annoying
for CCD using.
