Manual sample indexing.
Holds 6 samples or filters, each 1 inch diameter.
Does not include filters.

FA-448-1 Order sorting filter assembly.

320nm, 590nm, 665nm, and 715nm order sorting
filters mounted in the FA-448 filter wheel assembly. *

FA-448-2 Motorized six position filter wheel with stepping motor

and FA-448-4 controller. Enables computer controlled
filter indexing through RS-232 port and front panel
switch. Does not include filters.
