Dioptric Correction (Only for Leica EZ4, Open Version)

Dioptric Correction

The adjustable eyepieces for the Leica EZ4 are also available with built-in diop- tric correction, allowing the microscope to be

used without glasses even by those with vision problems. The correction comprises a maxi- mum of ±5 diopter settings.

Users with normal vision do not need adjus- table eyepieces. An adjustable eyepiece is sufficient for mild shortsightedness.

If vision is extremely poor or when graticules are used, two adjustable eyepieces are needed.

When the diopters are regulated exactly, the sharpness is constant over the entire magnifi- cation range (=parfocal).

Once the diopters have been set, the procedure does not have to be repeated. Simply restore your diopter values on the eyepiece before beginning work with the stereomicroscope

Adjusting
