Leica DM1000 LED manual Assembly Adjusting the Focus Stop, Stage Lock

6. Assembly

Adjusting the Focus Stop

The focus stop is preadjusted by the factory to prevent collision with objectives. The focus stop should be set approx. 0.3 mm higher as the focal plane to enable focussing of the samples of dif- ferent thickness.

If a readjustment is necessary, adjust as following:

•Lower the stage by rotating 1/2 turn of the coarse adjustment knob

•Loosen the focus stop screw on left hand side of microscope

•Move stage to desired focal plane (preferably approx. 0.3 mm higher)

•Tighten focus stop screw

Stage Lock*

The stage lock is mounted in the same hole as the stage drive (in case of ErgoStages, it can be mounted on the opposite position in addition to stage drive).

The mounting of stage lock is similar to mounting of the stage drive:

•Loosen the locking screw (5.1) on the left side underside of stage and move the stage all the way back

•Loosen the screw for coaxial pinion (6.1), remove the coaxial pinion, and attach the stage lock with this screw

•Loosen the stage lock screw and pull the stage forward to the desired position

•Retighten the locking screw (5.1) underside of stage

•Press the pinion of the stage lock against the rack and retighten the stage lock screw
