Description
Eliminating messy oil immersion maintenance from student laboratory benches, the Evident CX23 RFS2 Binocular Plan LED Laboratory Gear delivers 40x to 400x magnification across an infinity-corrected UIS2 optical path. Widefield 10x eyepieces provide a 20mm field number. The dry three-objective suite streamlines routine tissue inspection, though resolving intracellular bacterial morphology requires adding a 100x oil lens.
A lightweight aluminum frame houses an inward-facing quadruple nosepiece loaded with 4x, 10x, and 40x Plan Achromat objectives plus one expansion port, an Abbe condenser (NA 1.25), and transmitted LED illumination. The wire-driven mechanical stage measures 120 by 132 mm with 76 by 30 mm travel. Coaxial focus provides 2.5-micron fine divisions with an autofocus stop, paired with a 30-degree inclined binocular head offering 48mm to 75mm interpupillary spacing.
Key Features of Evident CX23 RFS2 Binocular Plan LED Laboratory Gear
High-school science classrooms, introductory botany labs, and veterinary clinics benefit from this dry-objective package during routine histological and parasitological screening. The missing 100x oil lens prevents oil contamination on dry lenses while leaving an open nosepiece port for future modular expansion.
- Infinity-corrected UIS2 optical system configured for 40x, 100x, and 400x dry magnification
- Plan Achromat objectives included: 4x/0.10, 10x/0.25, and 40x/0.65 with one spare port
- Binocular viewing head with 30-degree inclination and 48mm to 75mm IPD adjustment
- Locked-on widefield 10x eyepieces with an expansive 20mm field number (FN 20)
- Built-in Abbe condenser (NA 1.25) with aperture diaphragm and clear color-coded guides
- Integrated transmitted LED illumination delivering 20,000 hours of consistent color temperature
- Wire-driven rackless mechanical stage (120 x 132 mm) with low-position coaxial controls
- Coaxial coarse and fine focus mechanism with 2.5-micron minimum fine graduations
Plan Achromat Optics & Dry Objective Resolution
Plan Achromat 4x, 10x, and 40x objectives provide crisp image flatness across the entire 20mm viewing circle, eliminating peripheral curvature when examining cross-sections of plant stems or animal tissues. The 40x objective provides a 0.65 Numerical Aperture with a generous working distance, resolving cell nuclei cleanly without requiring immersion oils.
Rackless Stage Mechanics & Portable Handling
Integrated carry handles and an embedded cord wrap bracket make transporting the 5.7 kg stand between classrooms safe and organized. The wire-driven mechanical stage glides smoothly across specimen slides without exposed metal rails, while the low-position coaxial controls keep wrist posture relaxed.
- Wire-driven stage translation eliminates side-protruding metal racks for safe operation
- Molded carry handles and rear power cord storage simplify multi-station lab setups
- Spare nosepiece port allows straightforward addition of specialized 20x or 100x objectives
