Re: Lots of issues...

Transmission data according to a Perkin Elmer Lambda 35 research spectrometer:

900-1100nm 87 to 93% transmission (interference between surface reflections has made this area less precise)

800nm   82% transmitted

750nm   41.7% transmitted

700nm   0.23% transmitted

600nm   4.1% transmitted

500nm   66% transmitted

400nm   53% transmitted

350nm   18% transmitted

300nm to 200nm less than 0.02% transmitted

From the areas under the spectra around 10% of the normalised transmitted light would be UV, visible light mainly blues & green s account for about 30% & NIR about 60%

Taking into account camera sensor response will boost the visible portion at the cost of both UV & IR.

The UV transmission is better than most filters, but both IR & visible are HUGE.
