BX-RLA2

REFLECTED LIGHT BRIGHTFIELD/

DARKFIELD ILLUMINATOR

This instruction manual is for the Olympus Reflected Light Brightfield/Darkfield Illuminator Model BX-RLA2.
The BX-RLA2 is capable of brightfield and darkfield observations under the reflected light when it is
installed on the BX51RF/BX51TRF system microscope frame together with the BXFM focusing unit. To
ensure the safety, obtain optimum performance and to familiarize yourself fully with the use of this unit, we
recommend that you study this manual thoroughly before operating the microscope. Retain this instruc-
tion manual in an easily accessible place near the work desk for future reference.
