Its beyond my certain knowledge. However, if the lamp assembly fits
the enlarger and can be adjusted for the longer FL lens it would work.
The source works by having a lamp of very small area and a condenser
lens which focuses the output at the entrance pupil of the lens. For
most enlarging lenses this will be somewhere between the iris
diaphragm and the rear element. Since you know about how far the lens
must be from the lamp for a given focal length and amount of
magnification you can find out if the thing is capable of focusing
there. A true point source like this must be focused every time the
lens focus is changed in order to have good uniformity of
illumination. On either side of the correct position the light will be
concentrated in the center of the image. The usual condenser enlargers
don't need this critical focusing because the light source is a rather
large and diffused, typically a lamp with an "opal" coating. The more
concentrated the source the more critical the system will be for lamp
focus. Slide and home motion picture projectors use lamps with a very
large area which is imaged on the film so they are also less sensitive
to lamp focus. However, many projectors do have adjustments which can
make a large difference in the uniformity of screen uniformity.
Theater projectors typically have small sources with a condensing
mirror so require careful alignment and lamp focus.
 Probably there is someone who reads this group who will have
specific informtion on the compatibility of this source with the
Focomat II.
