2X Biological Microscope Eyepiece Achromatic Diameter 23.2mm

2X Biological Microscope Eyepiece Achromatic Diameter 23.2mm

The 2X Biological Microscope Eyepiece Achromatic with 23.2 mm diameter is a standard optical component for biological microscopes. It provides 2X magnification, fits most common microscope models, and meets International DIN/JIS achromatic standards. Designed for clear, distortion-free imaging at low to medium magnification levels.

  • 2X magnification increases total system magnification without changing objective lenses
  • 23.2 mm outer diameter ensures compatibility with standard microscope eyepiece tubes
  • Achromatic design reduces chromatic aberration for sharper, clearer images
  • Low-cost upgrade to enhance magnification and viewing clarity on existing biological microscopes

FAQ

What magnification does this eyepiece provide?
2X total magnification when used with a standard objective lens.
Is this eyepiece compatible with my biological microscope?
Yes, if your microscope has a 23.2 mm eyepiece tube. Most standard biological microscopes use this size.
Does it have a diopter adjustment?
No, this is a fixed-focus achromatic eyepiece without diopter or reticle.
Can I use it with a stereo or metallurgical microscope?
Not recommended. This eyepiece is designed for biological microscopes with standard 23.2 mm tubes and optical alignment.
What is the optical standard?
Achromatic, compliant with International DIN/JIS standards for color correction.
