Overview
60x Silver Microscope Objective with Achromatic Optics and Aperture 0.85 for Biological Microscope and Conjugate Distance 185 mm

The 60x microscope objective is one of the strong objectives used in biological microscopes for observing fine details of cells and small organisms without immersion oil. The numerical aperture 0.85 is indicated on the silver casing marked S60/0.85 along with the specification 160/0.17. This indicates that the optics are designed for a mechanical tube length of 160 mm and a cover glass thickness of 0.17 mm. Achromatic optics reduce chromatic fringes that would obscure the outlines of observed structures at high magnifications. The conjugate distance 185 mm is crucial for proper alignment with the microscope.

  • High Magnification 60x – the objective is used for detailed viewing of the specimen when the observed area has been located and focused using lower power objectives, allowing for closer examination of individual cells, their walls, nuclei, or other small structures within the specimen.
  • Dry Objective with Aperture 0.85 – the casing lacks the OIL designation, indicating that the objective is used without immersion oil, yet it offers a high numerical aperture for resolving fine details.
  • Cover Glass 0.17 mm – the optics are adapted for specimens covered with standard thickness cover glass, which is important for sharp and high-contrast images without blurred edges in high magnification objectives.
  • Compatibility with 160 mm Tube – the objective is suitable for microscopes that operate with a mechanical tube length of 160 mm and a conjugate distance of 185 mm.
  • Blue Stripe – the dark blue ring below the label distinguishes the objective from others in the revolving nosepiece, while the knurled black section below it provides a secure grip during changes.
  • Thread for Revolving Nosepiece – the objective screws into the microscope via a thread at the top and, once screwed in, occupies a position among other objectives in the assembly, usually behind an objective with lower magnification, allowing for progression from lower to higher magnification when rotating the nosepiece.

  • 1x Achromatic 60x Objective

The sixty times objective expands the capabilities of the biological microscope with high magnification, which is available even without the use of immersion oil. It is applicable for examining blood smears, plant cells, protozoa in water droplets, and other specimens where it is necessary to discern fine internal structures. At high magnification, the working distance between the lens and the specimen is small, therefore focusing must be done slowly and carefully to avoid contact between the front lens and the cover glass. Before purchase, it is sufficient to verify that the microscope uses optics with a conjugate distance of 185 mm and a tube length of 160 mm. This compact objective with achromatic optics will complement the setup in school laboratories, biological clubs, and home microscopy, filling the gap between medium and highest magnification.
