Typically includes:
• Leica HC PL FLUOTAR 10x/0.30 ∞/-/D objective lens (506505)

The Leica HC PL FLUOTAR 10x/0.30 (part number 506505) is a plan fluorite (semi-apochromatic) infinity-corrected microscope objective designed for use on Leica DM series upright and inverted microscopes equipped with an M25 objective thread. The HC (High Class) designation indicates superior optical correction and transmission performance. The PL (Plan) correction ensures flat-field imaging edge to edge, while the FLUOTAR fluorite element construction delivers enhanced chromatic and spherical aberration correction compared to achromats, making it well suited to fluorescence, brightfield, and phase contrast microscopy.

The objective is designed for use without a cover glass (denoted by the "-" cover glass designation) and carries the "D" designation indicating suitability for use with a condenser iris diaphragm. Its generous 11.0 mm free working distance makes it particularly practical for applications involving thick specimens, culture dishes, or multi-well plates.

Typical applications include routine biological research, histology, pathology, haematology, microbiology, oncology, and materials science.
