OLYMPUS CX21 ORIGINAL MICROSCOPE

Optical System & Performance

• UIS2 Optical System: Uses Olympus’s Universal Infinity System optimal optics for high resolution and excellent contrast across the viewing field — even at higher magnifications.
• Plan Achromat Objectives: Typically includes matched 4×, 10×, 40× objectives (and often optional 100× oil‑immersion) that provide flat, clear images with minimal distortion.
• Eyepieces: Standard 10× eyepieces with broad field number offer bright, wide views of specimens.
• Magnification Range: When combined with the objectives, yields common observation magnifications from ~40× up to 1000× (with oil immersion).

⚙️ Mechanical & Structural Features

• Binocular or Monocular Head: Comfortable viewing and interpupillary adjustment allow for prolonged use without fatigue.
• Rackless Mechanical Stage: Smooth, wire‑driven stage movement (typically 120 × 132 mm) enhances specimen positioning without exposed gears that can catch or wear.
• Quadruple Nosepiece: Allows easy rotation between objectives while maintaining optical alignment.
• Abbe Condenser with Iris Diaphragm: Optimizes contrast and resolution for transmitted bright‑field viewing.
• Coarse & Fine Focus Controls: Precise focusing mechanism with adjustable tension provides smooth adjustment down to fine focus steps for detailed studies.

💡 Illumination

• Built‑in Transmitted Light Source: A 6V, 20W halogen lamp is standard, offering bright and stable illumination for viewing stained or transparent specimens.
• Some variants use an LED illuminator, providing long lamp life, consistent colour temperature, and reduced heat buildup.

🧠 Design & Usability

• Ergonomic Build: Intuitive control placement and compact design make it comfortable for extended usage in labs or classrooms.
• Anti‑Fungus Optical Treatment: Optical components are treated to resist fungal growth — a vital feature in humid environments.
• Component Security: Critical optical parts are factory‑attached to reduce risk of dropped objectives or lost components.
• Adjustable Interpupillary Distance: For comfortable binocular viewing between different users.
