cover

the numerical aperture of the objective is 0.7 or higher (except immersion objectives)

and no correction collar is provided, the resolving power deteriorates greatly, if

cover

glass thickness deviates from the above listed value.

NOTE: In some countries a 0.17 mm thick cover glass corresponds to a #1

cover glass.

except 0 Plan 40X. S Plan Apo 40X and S Plan lOOX.
