Looks like a typo--google "Componon-S"
It is a high quality enlarging lens.

It can be used for closeup work, Schneider sold them in shutter for that purpose. Per Schneider's documentation -- root around on the site Klaus directed you to -- Componons are optimized for 10x enlargment. This is equivalent to taking at 1:10.
If you want a Schneider enlarging lens to use for close-up work a Comparon (optimized for 2x - 6x) is probably a better choice. And some Comparons have another advantage: the 75 fits a #00, 105 and 150 fit #0. With these lenses, reversing the lens for working at magnifications above 1:1 requires only swapping the cells from front to rear and vice versa.
The 150 Componon fits a #1 shutter, which doesn't have the same threading front and rear, so using it above 1:1 is more difficult.
