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 particularly suitable for this purpose.
To prevent oil contamination of the specimen when the nosepiece is turned, the resilient mounts of the
immersion objectives can be locked in their lifted position by turning them clockwise (do not forget to
unlock them again!).

Eyepieces
The field-of-view 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 refers to the 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.
