Solar observation filters transmission. Help.

[lazar_zivadinovic]

Hello guys, im new to the formun and im a apsolute beginer in filters and optics and things like that.

So, im currently working on high-school project on how to determinate temperature of suns spots. Now, im programming in C++ a little bit and im doing fine, but the one thing i can't find on the internet is datasheet of solar filters transmission. I dont need a filter that pass only one spectral line, i need a filter with continuum of 100-200 nm (higher or lower is ok, but this is just fine), and in the range of 200-2000 nm. So can somebody help me and direct me to one of these sites that have solar filters datasheets, i founded something like this http://www.sonnen-fi...1/BAA-rot-G.gif , and that's ok, but i need that in .txt with tab, coma or space separated file.

eg.

nm %

650 80

651 80.4

652 81.26

Welcome to SGL!

There's no "data sheets" I've come across so far.

The site you've hit has one of the best collections of transmission graphs....

Note: not all commercial filters give information beyond 1200nm - this being the general limit for CCD sensitivity.

In the library area of Solar Chat, we do have many graphs for various filters.

Hope this helps.
