When immersion objectives are used, the air between the cover slip and the objective is replaced by a
liquid, which in most cases is immersion oil. The plastic oiler containing 20 ml of Immersol 581 F
immersion oil (n
D
= 1.518) is ideal for this purpose.
To prevent oil contamination of the specimen when the nosepiece is turned, the snap-in sockets of the
immersion objectives can be locked in their raised position by turning them clockwise (do not forget to
re-release them!).

Eyepieces
The field number of the eyepieces PL 10x/25 Br. foc. and E-PL 10x/25 Br. foc. is 25 mm; that of eyepieces
W-PL 10x/23 Br. foc. and E-PL 10x/23 Br. Foc. is 23 mm.
W-PL and PL in the eyepiece designation indicates excellent image flatness up to the edge of the field of
view.
If required, eyecups for the eyepieces can be ordered under Cat. No. 444801-0000-000.
