Leica PL APO 50x / 0.90 Microscope Objective

This is a Leica PL APO 50x / 0.90 Microscope Objective.

Yet another very recent objective well suited to semi-conductor examinations (as well as general metallography). This is a Leitz Germany Plan Apo 50x / 0.90 lens, catalog number 567 056. This objective does not appear to have been used, however there is a number “632” engraved on the nomenclature ring. Otherwise, there are no blemishes discernable either cosmetically or optically.

Plan Apochromat optics are corrected for a super-wide field of view index of 28 mm. The Apochromatic color correction is the highest obtainable. This is not an EPI version of the lens; in other words it does not include an annular condenser system concentric with the main objective for dark field illumination. It is strictly a bright field lens. It is not designated as strain-free which means it may not produce the best images when using interference contrast, but most objectives of very recent manufacture are very free of strain issues. The objective is spring-loaded for specimen and objective protection.

The lens is corrected for infinity tube length, and must be used on samples without a cover slip! The lens does have the standard RMS (20mm) mounting thread because it doesn’t have to accommodate the epi-illumination darkfield optics. In order to be used on the same nosepiece with the epi-objectives, an RMS to 32mm thread will be required. The objective will work with the Ergolux, Metalloplan, MM-6, and similar microscopes outfitted with an RMS type vertical illuminator. When fitted with the adapter, it is suitable for the relatively recent Leitz microscopes which include the Ergoplan and the DMR series reflected light instruments as well as the current DM 4000, 4500, and 6000 M microscopes.
