Spectral information on fluorophores, filters and lamps
- - an essential tool to set up the excitation and emission of fluorophore
- - an essential tool to set up a fluorescent microscope
- (University of Arizona; contains many fluorescent proteins)
- (TU Graz) - very detailed and complete spectral information of fluorophores, with browsing by application (eg. pH indicators, DNA dyes, ion sensors)
- hosted by Becton Dickinson
- (Cornell University)
- Interactive lists at :
Deconvolution
- - calculates the optimal sampling rate for microscopic image acquisition (Nyquist rate = 2x maximal resolution) Scientific Volume Imaging

Protocols, tips and tricks - sample preparation
This is a growing collection of methods and techniques used in the facility, representing the enormous range of expertise of our microscopists. Everybody is very much invited to contribute with their own protocols. Protocols are provided as Word files, so they can be downloaded and edited as required.
