Description
Eliminating blinding glare spikes during multi-slide student screenings, the Optika B-382PH-ALC Phase Binocular Microscope features an integrated Automatic Light Control (ALC) system. The onboard ALC sensor continuously measures transmission and automatically adjusts the 3.6W X-LED3 output when rotating between objectives, protecting user vision from sudden brightness jumps. Built on a finite 160 mm optical track, it provides 100x and 400x dry phase-contrast magnification via two DIN Plan-Achromatic Phase lenses: 10x/0.25 and spring-loaded 40x/0.65, completely bypassing messy immersion oils.
Its 216 x 150 mm double-layer mechanical stage uses an internal belt-drive mechanism (78 x 54 mm XY travel), eliminating exposed toothed racks that snag sleeves or scratch hands. Transmitted light is focused through a 1.25 NA phase condenser fitted with a custom phase slider card slot. The 30-degree inclined binocular head rotates 360 degrees and carries high-eyepoint WF 10x/20 mm eyepieces across an adjustable 48 mm to 76 mm interpupillary span. Total chassis weight is 7.0 kg, operating on universal 100-240V AC power with coaxial 2-micron fine focus knobs.
Key Features of Optika B-382PH-ALC Phase Binocular Microscope
An educational and clinical binocular phase-contrast microscope featuring Automatic Light Control (ALC) and a belt-driven mechanical stage. Combines two dry DIN Plan phase objectives with an oil-free 400x magnification ceiling, 3.6W X-LED3 illumination, and a 1.25 NA phase condenser.
- Automatic Light Control (ALC) system maintains constant visual brightness across objective swaps
- Dry DIN Plan-Achromatic Phase objectives: 10x and spring-loaded 40x (no oil required)
- Belt-driven 216 x 150 mm mechanical stage eliminates protruding gear racks for user safety
- Patented X-LED3 3.6W white LED light platform delivers daylight-balanced transmitted rays
- Pre-centered phase contrast condenser (NA 1.25) with dedicated sliding phase card slot
- 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 7.0 kg cast-metal chassis provides complete vibration-free benchtop stability
Automatic Light Control & Dry Phase Contrast
Switching from a high-power 40x lens back to a 10x 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. Because this configuration uses dry 10x and 40x phase lenses, technicians can evaluate living cell suspensions, yeast cultures, and urine sediment without dealing with sticky immersion oils.
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
- Dry 40x objective eliminates oil contamination and lens cleanup routines
- Belt-driven stage mechanism prevents hand injuries and gear wear over long shifts
