Offering 40× magnification with a numerical aperture (NA) of 0.65, this objective delivers crisp, high-contrast images with excellent detail — perfect for cellular and fine structural studies. Featuring a Plan Achromat optical design, this objective corrects chromatic and spherical aberrations to produce a flat, well-corrected image across the field of view. This reduces optical distortion and maintains sharpness from edge to edge, an important benefit when capturing high-resolution micrographs or performing quantitative image analysis. With a working distance of approximately 0.66 mm, this objective is optimized for use with standard microscope slides and cover glass (~0.17 mm). Its standard RMS threaded mount ensures compatibility with a wide range of upright research microscopes, making it suitable for laboratory workflows across biological, clinical, educational, and materials science environments. 🔎 Typical Applications Brightfield microscopy Fluorescence imaging Differential Interference Contrast (DIC) Phase contrast microscopy High-resolution structural imaging 📊 Key Specifications Specification Details Magnification 40× Numerical Aperture (NA) 0.65 Optical Design Plan Achromat Working Distance ~0.66 mm Field Number 22 Wavelength Range ~380–900 nm Mount RMS (20.32 × 36 TPI) Immersion Medium Air (dry) Parfocal Length ~45 mm Compatible Cover Glass ~0.17 mm Condition New ordering
