Condition: Used

The Leica 506503 HC PL FLUOTAR 20x/0.50 ∞/0.17/D is a used infinity-corrected dry objective in good condition, fully tested and functioning as intended. It is suitable for brightfield and fluorescence microscopy on Leica DM series and compatible platforms.

What is typically included:
• Leica 506503 HC PL FLUOTAR 20x/0.50 ∞/0.17/D objective lens

The Leica HC PL FLUOTAR objective series represents Leica Microsystems' semiapochromatic (Fluotar) corrected optics, designed for use across brightfield, fluorescence, DIC (differential interference contrast), and phase contrast applications. The HC (High-Contract) designation reflects the series' optimised transmission and contrast characteristics suited to routine and research-grade microscopy.

The 506503 HC PL FLUOTAR 20x/0.50 ∞/0.17/D is an infinity-corrected dry objective designed for use with a 0.17 mm coverglass. It mounts via an M25 x 0.75 mm objective thread and is compatible with the Leica DM series of upright microscopes. The "D" designation denotes DIC (differential interference contrast) capability using the appropriate prisms (D/D1 series).
