I confirm by mail my wish to buy that meter directly to Ian.
Thanks for making that possible.

> Dear list,

> wavelengths (including visible light). This is pretty tricky to do without
> the proper tools. I had to custom design a combination of 4 filters to
> achieve this and it required access to specialized optical instruments to
> measure their optical transmission - tools which most artists/photographers

> i) Since I have significantly depleted my existing inventory I would need

> ii) Also I will need to increase the price (!) - sorry about that but the

> (which is the reason that we closed the store in the first place). I'll
> need to set the price at $299. I realize this might be a problem for many
> people, but it's an unfortunate fact. Again, sorry.
> iii) Since I will need to reorder much of the inventory there will be an
> inevitable delay of 4-6 weeks before I could ship. One of the major
> components has a 4 week lead time.
> iv) To keep things manageable I'll probably only offer the PPM-2 long
> wavelength version (with the external sensor). This was, by far, our most
> popular version, and I expect that most people would order this anyway.
> So how to proceed? Might I suggest that you circulate this to the
