L.
Rotate the phase turret annuli control until the number 10 can be seen at front of phase turret condenser
assembly. Annuli must click into position to assure proper centering.
M. Using condenser focusing control knob, focus the bright annuli ring located in phase turret annulus condenser.
N. Observe the two rings in the field of view.
1.
The dark larger annulus ring is located in the objective lens
2.
The bright smaller annulus is located in the phase turret condenser.
O. Centering of the annuli:
P.
Depress the two knurled head centering screws that extend out from each side of phase turret condenser
assembly until they engage the hex socket screws of annuli centering
mechanism.
Q. While keeping the two centering screws depressed, look through the centering telescope and observe rings
located in objective and phase turret condenser. Rotate the centering screws in or out, moving image of the
smaller bright annulus ring annuli located in phase turret condenser until it is centered to the larger dark annulus
located in the objective. Both rings must be concentric to each other to achieve maximum performance. Make
sure that the knurled head centering screws are disengaged from the hex socket screws of annuli centering
mechanism and in the “out” position before rotating phase turret condenser.
R. Repeat above steps with the 20x, 40x and 100x phase objectives, making sure to position the corresponding
annuli of phase turret condenser to matching objective indexed in optical path. (Plan 10Ph/0.25 matched to the
number 10 on rotating phase turret condenser.)
S.
It will be necessary to focus the telescoping eyepiece and phase turret condenser with each objective lens.
T.
When you have adjusted all 4 annuli to their respective objective lenses remove centering telescope from
eyepiece tube and install eyepiece.
1.
Microscope is now ready for use.
2.
The phase objectives will work well as standard bright field objective lenses. To view in bright field simply
position the O position to the front of condenser turret and adjust condenser and iris diaphragm for standard
use.
