Condition: Used

The Leica 567010 PL FLUOTAR 2.5x/0.07 is a used infinity-corrected objective in good condition. With its RMS thread, 9.2 mm working distance, and cover-glass-insensitive design (∞/-), it is well suited for low-power survey imaging across materials science, life science, and fluorescence applications.

What is typically included:
• Leica 567010 PL FLUOTAR 2.5x/0.07 ∞/- objective lens

The Leica PL FLUOTAR 2.5x/0.07 (catalogue number 567010 / 11567010) is a low-magnification, infinity-corrected microscope objective from Leica Microsystems, belonging to the PL FLUOTAR series.

PL FLUOTAR objectives are powerful universal objectives with outstanding chromatic correction for at least three wavelengths, making them highly suitable for fluorescence imaging. The PL (plan) designation indicates flat-field correction computed for up to 28 mm field diameter in the intermediate image plane, ensuring edge-to-edge sharpness across large specimens. Objectives are manufactured from special glass to enable maximum light transmission, making them efficient photon collectors in fluorescence microscopy.

The 2.5x/0.07 variant is optimised for wide-area survey imaging, whole-slide overview, large specimen inspection, and low-power fluorescence screening. The cover-glass-insensitive correction (∞/-) allows use with or without a coverslip, making the objective versatile for both life science and materials/metallurgical applications.

Key Specifications:
Magnification: 2.5x
Numerical Aperture (NA): 0.07
Tube Length Correction: Infinity (∞)
Cover Glass Correction: None (-) — insensitive to cover glass
Objective Thread: RMS (Royal Microscopical Society standard)
Free Working Distance (FWD): 9.2 mm
Flat Field Index: 28 mm
Adjustment Length: 45 mm
Immersion Medium: Dry
Correction Class: PL FLUOTAR (plan-corrected fluorite)
Leica Part Number: 567010 / 11567010

Typical Applications:
- Low-power brightfield survey and overview imaging
- Wide-field fluorescence screening
- Whole-slide and large specimen imaging
- Materials science and metallurgical inspection
- Life science research and pathology overviews

Compatibility: Suitable for use on Leica DM series upright and inverted microscopes and other instruments accepting RMS-threaded objectives. Earlier Leica/Leitz microscopes using RMS thread are directly compatible; M25-thread nosepieces require an M25/RMS adapter.
