BH2-CA Magnification Changer
The BH2-CA Magnification Changer (Olympus B-L0118) is the BH2 version of the venerable Zeiss Optovar. The BH2-CA includes selectable magnification factors of 1.0x, 1.25x, and 1.5x, as well as a focusable Bertrand lens that allows the operator to view the exit pupil of the objective for phase contrast and polarizing applications. The BH2-CA was available in black and cream versions. The various magnification factors are useful for photomicrography applications, allowing intermediate magnifications between the standard objectives. The BH2-CA allows a standard set of 4x, 10x, 20x, 40x, and 100x objectives to provide magnifications of 4x, 5x, 6x, 10x, 12.5x, 15x, 20x, 25x, 30x, 40x, 50x, 60x, 100x, 125x, and 150x.
