Hello all, I've been wondering what the difference is between eyepiece types SWK and SWHK 10x/26.5 for the super widefield tube of the BH2 series. H could stand for High eyepoint, but the difference is minimal and in practise not notable. Measured (with some difficulty) 16.5 mm for the SWHK and 15 mm for the SWK.
Best wishes, René
the SWK eyepieces seem to belong to the trinocular tube for the vanox microscopes.

but I have no idea if they are just rebrands of the SWHK.
