recommendations for photometer

[Emir Khatipov]

Just remembered that there was a cheap standalone spectrophotometer
Ultraspec II (LKB) that could be hooked up to a computer through RS232, and
there was a DOS-based soft to drive the instrument. But that was at least 13
years ago. I could not get any information from LKB about any analogous
system, so I guess LKB is a good idea to try to get in touch with.
