- Precision Optical Alignment: Achromatic, parfocal, and parcentered objectives ensure accurate color reproduction and consistent focus between magnifications.
- Professional Mechanical Stage: Low-profile stage with coaxial X-Y controls and built-in 1.25 N.A. Abbe condenser allows smooth, precise specimen positioning.
- Durable All-Metal Construction: Rugged gray enamel body and heavy-duty frame designed to withstand years of classroom or laboratory use.
- Accurate Focusing Controls: Low-position coarse and fine focus knobs with tension adjustment and safety rack stop for stable, protected operation.
The National 133-134 CLED Monocular LED Microscope Series combines precision optics, durable construction, and classroom versatility—making it ideal for middle school, high school, and college-prep biology programs. Built for lasting performance, these microscopes feature cool, bright LED illumination that delivers crisp, white light without heat damage to live specimens.
The 133-CLED model includes three achromatic DIN objectives (4X, 10X, 40XR) for clear, parfocal, and parcentered imaging up to 400X magnification, perfect for general biology and cell observation. The 134-CLED model expands capability to 1000X magnification with the addition of a 100XR oil-immersion objective, supporting advanced studies in microbiology and tissue analysis.
Both models include a precision mechanical stage with X-Y controls, Abbe condenser with iris diaphragm, and coaxial coarse and fine focusing for smooth, precise control. The rugged all-metal frame, ergonomic monocular head (360° rotatable), and locked-on components ensure long-term durability in demanding educational environments.
Reliable, bright, and easy to use—the National 133-134 CLED Series is a trusted choice for educators and students seeking professional-quality optics for every level of science instruction.
