N2 laser and Zeiss microscopes

[Ralf Baumeister]

We currently have a dispute with our laser safety officer
about which filter sets to use with the LSI 337 N2 laser and
the Zeiss Axioskop. We use the coumarin cuvette and, therefore,
get an excitation of 437 nm from the laser.

Which filters (split filter, emission filter) are people using
in the filter slider of the Zeiss microscopes? Which safety precautions
do you have?

Thank you

Ralf Baumeister
