Fig 2. Top View of L to R Beam Selector™ Optical Unit
Fig 2 shows a top view of an
L to R
Selector™ optical unit alone and
Fig 3 shows the same
L to R
Selector™ optical unit but from the
underside. From the Figs 2 and 3, the light beam sequence for
passage of light through the Selector™ optical unit for an
L to R
direction is as follows:-
The light beam from the source is directed to a fixed angled mirror (
5
)
on its mount post and onto another fixed angle mirror (
6
) on its mount
post. The light beam is then projected to an
input
ellipsoid mirror E1
(
7
) which then focuses the light onto the surface area of a sample held
in a cup that is positioned on top of the sample post (
3
) – see Fig 1. (In
Fig 2 the E1 mirror (
7
) has been indicated, but it is positioned
underneath the top cover of the ellipsoid mirrors arm assembly (
4
) –
see Fig 1.) It is easier to see E1 (
7
) from the underside view of Fig 3.
