interferometer Interferometer (transmitted wavefront) analysis was only done by manufacture becasue it is done with a HeNe laser (632.8 nm) which can only transmit through these two filters.
Transmitted wavefront of SDSS r-band filter:
p-v 0.097 wave over 30 mm x 30 mm (wave: 632.8 nm)

Transmitted wavefront of clear filter:
p-v 0.117 wave over 30 mm x 30 mm (wave: 632.8 nm)
