195EA 4X 10X 20X 40X 60X 100X Achromatic Microscope Objective

195EA 4X 10X 20X 40X 60X 100X Achromatic Microscope Objective

The 195EA series achromatic microscope objective lens offers 4X, 10X, 20X, 40X, 60X, and 100X magnification options for biological and metallurgical microscopy applications. Designed for use with standard biological and metallurgical microscopes, the lens series provides clear, distortion-free imaging with a 160 mm tube length and 0.17 mm cover glass thickness. It is compatible with both monocular and binocular microscope bodies.

  • Six standard magnifications (4X to 100X) for flexible use across sample types and inspection needs
  • Achromatic correction reduces chromatic aberration for accurate color representation
  • 160 mm tube length standard for compatibility with most biological and metallurgical microscopes
  • 0.17 mm cover glass thickness ensures optimal performance with standard slides
  • Robust metal housing with threaded mount for secure attachment and long-term stability

FAQ

What is the tube length for this objective?
160 mm, standard for most biological and metallurgical microscopes.
Can I use this with a 170 mm tube length microscope?
No. This objective is designed for 160 mm tube length systems. Using it on a 170 mm system may cause focus issues or image degradation.
Is this objective compatible with oil immersion?
No. This is a dry objective. Use oil immersion objectives only for 100X and higher magnifications with immersion oil.
What is the working distance at 100X?
0.1 mm. Handle with care to avoid contact with the slide.
What magnifications are available?
4X, 10X, 20X, 40X, 60X, and 100X.
