Description
Eliminating peripheral blur during routine cytology screenings, the Optika B-292PLi Binocular Compound Microscope provides flat-field optical precision across clinical diagnostic desks. Operating on an infinity-corrected IOS optical train, it delivers 40x, 100x, 400x, and 1000x magnification via four IOS N-PLAN plan-achromatic objectives: 4x/0.10, 10x/0.25, spring-loaded 40x/0.65, and spring-loaded 100x/1.25 oil immersion. Superior optical correction flattens image curvature across the 20 mm field of view, keeping stained blood films and urine sediment sharp from center to margin.
Its 150 x 139 mm double-layer mechanical stage features an enclosed belt-driven movement mechanism (75 x 33 mm XY travel), eliminating exposed metal gear racks for smooth, snag-free slide navigation. Transmitted illumination is supplied by an ultra-bright X-LED3 3.6W white LED system with custom condensing collectors, focused through an Abbe 1.25 NA condenser equipped with an adjustable iris diaphragm. Built on a 6.5 kg cast-metal chassis measuring 235 x 290 x 370 mm, the stand features coaxial coarse and fine focus knobs calibrated to 2-micron graduations, running on universal 100-240V AC power via an external switching adapter.
Key Features of Optika B-292PLi Binocular Compound Microscope
An advanced biological binocular compound microscope featuring a belt-driven mechanical stage and IOS infinity optics. Combines four IOS N-PLAN objectives with an X-LED3 3.6W light engine, an Abbe 1.25 NA condenser, and 2-micron coaxial focusing for clinical and veterinary labs.
- IOS N-PLAN plan-achromatic infinity objectives: 4x, 10x, spring-loaded 40x, and 100x oil
- Innovative belt-driven 150 x 139 mm mechanical stage eliminates protruding gear racks
- Patented X-LED3 3.6W white LED light platform delivers daylight-balanced illumination
- Height-adjustable Abbe 1.25 NA condenser equipped with an adjustable iris diaphragm
- Widefield high-eyepoint WF 10x/20 mm eyepieces on a 30-degree inclined binocular head
- Quadruple revolving nosepiece revolving smoothly on precision ball bearings
- Coaxial coarse and fine focus drive with calibrated 2-micrometer (0.002 mm) graduations
- Solid 6.5 kg cast-metal chassis provides complete vibration-free benchtop stability
IOS N-PLAN Optics & Transmitted Brightfield Clarity
Color-corrected IOS N-PLAN objectives eliminate spherical curvature across the visual field, keeping stained leukocytes and bacterial clusters sharp from center to perimeter. The patented X-LED3 light engine produces intense, color-stable white illumination that matches a 50W halogen bulb while running completely cool. Spring-cushioned mounts on the 40x and 100x objectives protect slide cover slips from accidental mechanical strikes during high-power focusing passes.
Belt-Driven Stage Safety & Binocular Viewing Comfort
Traditional mechanical stages feature sharp metal gear racks that stick out sideways, catching lab coat cuffs during repetitive work. The belt-driven stage on the B-292PLi moves smoothly on internal belts, providing whisper-quiet translation with zero backlash across a 75 x 33 mm range. Binocular viewing through widefield 20 mm eyepieces relieves eye strain during multi-hour sorting shifts, while coaxial focus knobs with 2-micron fine division markings allow delicate focal plane control through living fluid mounts.
- Belt-driven stage mechanism prevents hand injuries and gear wear over long shifts
- X-LED3 light engine delivers intense, daylight-balanced illumination without thermal drift
- Coaxial focus mechanics with 2-micron graduations provide delicate focal plane control
