some information for DIC

LHS-H100P-1 lamp houses are available, unlike filter holders
that space lamp houses 65mm from universal vertical illuminators,
to which they fasten by 3 screws around a 36mm cylindrical stub.

Köhler mystery

Optiphot field lens focuses LHS-H100P-1 lamp filament on ground glass,
changing distance between lamp housing collector lens and field lens
does not much affect field lens to ground glass focus distance (135mm),
suggesting lamp housing collector lens rays are substantially collimated...
but Optiphot 150 illuminator lamp house extension has a lens...???
