Optika B-382PH-ALC Binocular Phase Contrast Microscope

The Optika B-382PH-ALC is a binocular upright microscope from the B-380 series, built for phase contrast work alongside brightfield and darkfield observation.

The die-cast aluminum body carries a transportation handle and a quintuple nosepiece, giving room for a full set of N-PLAN and W-PLAN PH objectives.

N-PLAN / W-PLAN PH Optics

The B-382PH-ALC uses N-PLAN 4x and W-PLAN PH 10x, 40x, and 100x oil objectives, giving 40x to 1000x total magnification on a 160 mm finite optical system.

• Quintuple reversed nosepiece on ball bearings
• Anti-fungus treated optics

5-Position Condenser for Three Techniques

The Abbe condenser has 5 positions covering brightfield, phase contrast at 10x/20x and 40x and 100x, and darkfield for dry objectives, at N.A. 1.25.

• Centerable, removable, with an iris diaphragm
• Focusable by rack and pinion

Automatic Light Control

The X-LED3 illumination supports both manual and Automatic Light Control (ALC), which adjusts brightness as the observation method changes between brightfield, phase contrast, and darkfield.

• 3.6 W X-LED3 source, 6,300 K color temperature
• Rated at more than 65,000 hours of lifetime

Rackless Stage and Coaxial Focus

The double-layer rackless stage moves 75 x 33 mm, with a coaxial coarse and fine focus system offering 25 mm coarse travel and 2 micron fine resolution.

• Upper stop to prevent objective-slide contact
• Adjustable tension, flat ergonomic knob

Ideal Applications

The B-382PH-ALC suits laboratories that regularly switch between brightfield, phase contrast, and darkfield on unstained or living samples.

• Live cell and unstained specimen observation with phase contrast
• Routine and research laboratory work needing multiple techniques
• Laboratories that value automatic brightness adjustment between methods
• Training environments teaching phase contrast alongside brightfield

Choose the B-382PH-ALC when:

• You need brightfield, phase contrast, and darkfield on one condenser
• You want automatic brightness adjustment between techniques
• You do not need infinity-corrected IOS optics
• A binocular head meets your documentation needs

Optika Value Proposition

Optika has manufactured educational and laboratory microscopes for more than 45 years and sells through dealers in more than 150 countries. The B-382PH-ALC carries the same X-LED3 illumination used across the Optika range, backed by a 10-year warranty on mechanical and optical parts and a lifetime warranty on the X-LED light source.
