Numerical Analysis of Variable Fluorescence

I have developed and maintain custom software to analyze variable fluorescence kinetics, such as those collected with Fast Repetition Rate Fluorometers or other similar instruments.  This software series is called “v” and is written in Matlab.  The latest versions are v6 and a companion compiled Windows executable, v6win, which are being beta-tested by several users worldwide. After this process, v6 will be released to the general public.

The most recent beta version (v6) is available upon request to users interested in implementing the types of corrections outlined in:
S. R. Laney and R. M. Letelier, Artifacts in measurements of chlorophyll fluorescence transients, with specific application to fast repetition rate fluorometry, Limnol. Oceanogr.: Meth. 6, 40-50, 2008

Updated information to Laney & Letelier 2008:

Neutral Density Filters: The 2" neutral density filter kit mentioned in this manuscript is no longer available from the vendor. A comparable kit of ten 2" absorptive filters can be ordered from Thorlabs (NEK01S).

Alternatively, individual filters can be bought instead to cover the range of transmittances shown in Figure 5 of Laney & Letelier 2008. In that study, up to nine filters were used to collect the data shown in Fig. 5.
