Dear microscopists and optical engineers,

I am looking into the assembly of a UV (355nm) scanning system coupled into the back of a Nikon Ti. We will use a CryLas 355 pulsed laser (FTSS355-Q3). I reckon that there are several commercial products for beam expansion, Galvo-scanner+theta lens, etc. My question is which ones to go for…

Thus, I was wondering about your experience with the performance of some commercial products you have used for this purpose.
- The scan lens (f-theta) and the Galvo-scan system and their software implementation (I looked at Camtech and Thorlabs).
- Would it make sense to build a beam expander (Galilean type) for this particular wavelength and save some $$? If so, which optics and provider would you suggest for 355 nm?
- Does anybody have experience with SillOptics beam expanders for UV range?
- Moreover, is there a tube lens out there that performs decently for this wavelength in conjunction with Nikons Plan Apo 40x 1.25W lambdaS objective?

Thanks for all the recommendations on this topic!

Ivo
