Description
Prevent sudden illumination flashes during slide reviews using the Optika B-382PLi-ALC Binocular Compound Microscope. The integrated Automatic Light Control (ALC) system continuously reads current light levels and automatically regulates LED voltage when rotating between objective lenses, maintaining a consistent, comfortable illumination level without manual dimmer adjustments. Powered by an infinity-corrected IOS optical train, it provides 40x, 100x, 400x, and 1000x magnification via four IOS N-PLAN flat-field objectives: 4x, 10x, spring-loaded 40x, and spring-loaded 100x oil immersion.
Its 216 x 150 mm double-layer stage features an enclosed belt-driven movement mechanism (78 x 54 mm XY travel), eliminating exposed metal gear racks for smooth, snag-free slide navigation. Transmitted light is driven by a patented X-LED3 3.6W white LED module focused through an Abbe 1.25 NA condenser with an iris diaphragm. The 30-degree inclined binocular head carries paired widefield high-eyepoint WF 10x/20 mm eyepieces across an adjustable 48 mm to 76 mm interpupillary span, supported by a 7.1 kg cast-metal frame with coaxial focus knobs calibrated to 2-micron graduations.
Key Features of Optika B-382PLi-ALC Binocular Compound Microscope
An advanced biological binocular microscope featuring Automatic Light Control (ALC) and a belt-driven mechanical stage. Combines four IOS N-PLAN infinity objectives with an Abbe 1.25 NA condenser, 3.6W X-LED3 illumination, and an oil-immersion 1000x magnification ceiling.
- Automatic Light Control (ALC) circuit automatically regulates brightness when swapping objectives
- IOS N-PLAN plan-achromatic infinity objectives: 4x, 10x, spring-loaded 40x, and 100x oil
- Innovative belt-driven 216 x 150 mm mechanical stage eliminates protruding gear racks
- Patented X-LED3 3.6W white LED illumination system matches a 50W halogen bulb in output
- 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
- Coaxial coarse and fine focus drive with calibrated 2-micrometer (0.002 mm) graduations
- Solid 7.1 kg cast-metal chassis provides complete vibration-free benchtop stability
Automatic Light Control & IOS N-PLAN Clarity
Switching from a high-power 100x oil lens back to a 4x scanner normally blasts the operator’s eyes with blinding light. The ALC sensor detects objective changes instantly, adjusting the 3.6W X-LED3 emitter to your saved baseline so your eyes never have to strain or readjust. The IOS N-PLAN objectives correct field curvature across the specimen field, keeping cellular membranes and nuclear details crisp from center to perimeter.
Belt-Driven Stage Safety & Binocular Viewing Comfort
The belt-driven mechanical stage encloses all drive teeth internally, preventing torn lab coat sleeves and scratched hands during fast multi-slide screenings. 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.
- Automatic Light Control eliminates eye fatigue caused by sudden brightness spikes
- Belt-driven stage mechanism prevents hand injuries and gear wear over long shifts
- Spring-loaded 40x and 100x objectives protect slide cover slips from accidental crushing
