Hi,
Thanks for the info. I bought an assortment of bits before GMN even went live (this was after and IMC a few years back) and thought I’d put something together but the road to hell….
So focused on developing the spectroscopy it was soon forgotten about, I recently found a couple of tiny board lenses in a box which prompted my question after seeing your pic. Might get around to it one day! ; – ))
cheers,
Bill.
