The Leica 506140 HCX PL APO CS 40x/0.85 CORR is a used dry apochromatic objective in good condition. Part number 506140 (full Leica catalogue number 11506140), this infinity-corrected lens features a correction collar spanning 0.11–0.23 mm coverglass thickness and a working distance of 0.24 mm, making it well suited to brightfield, fluorescence, and confocal scanning applications.
No specific accessories are mentioned in the existing description.
The Leica HCX PL APO CS 40x/0.85 CORR (part number 11506140 / 506140) is a plan apochromatic, infinity-corrected dry objective from Leica Microsystems, designed for high-resolution transmitted light and fluorescence microscopy. The HCX designation denotes Leica's high-correction optical system, PL indicates planar (flat-field) correction, and APO confirms full apochromatic chromatic aberration correction across multiple wavelengths. The CS suffix signifies optimisation for confocal scanning applications. The integrated correction collar allows the user to compensate for varying coverglass thicknesses, minimising spherical aberration and maintaining image quality across different specimen preparations.
Key Features:
- Plan apochromatic (PL APO) colour correction for precise fluorophore colocalization
- Correction collar (CORR) for coverglass thickness compensation
- Infinity-corrected optical design for use with modern Leica DM series microscopes
- Dry (no immersion medium required)
- M25 objective thread for broad Leica DM platform compatibility
- Suitable for brightfield, DIC, fluorescence, and confocal scanning microscopy
Specifications:
