Epiplan 40 / 0.60 Pol Short-Mount Microscope

This is a very nice Zeiss LD Epiplan 40 POL objective for work in reflected polarized light. Because it is strainfree, it is suitable for use with the Nomarski interference contrast method (requires the addition of an INKO LD 40 attachment, not included). The objective has a numerical aperture of 0.60. By selection of suitable cover shrouds, the coverglass correction of the objective can be altered from D=0 (no coverglass) to D=1.5 mm. The shroud included with this objective has no glass element, therefore the objective is presently corrected for imaging through a 1.5mm thickness of glass. This would be suitable for looking at semi-conductor mask geometries with the substrate side toward the objective.
