Leica M205 FA Objective Nosepiece, Parfocal work, Objective change, Technical constraints

The Objective Nosepiece

Use

The objective nosepiece enables you to switch between two objectives using just one hand movement, for example between a 1× and a 2× planapochromat.

Parfocal work

With the new M series objectives, the parfo- cality is maintained even when objectives are changed, meaning that the specimen remains in sharp focus during the change.

Older Leica objectives can continue to be used, but without parfocality during the

objective change.

Technical constraints

•The objective nosepiece cannot be used together with the LED5000 MCI™

system illumination, as the objective nosepiece can no longer be rotated.
