Optika B-292 Binocular Brightfield Microscope for Routine Laboratory Use

The Optika B-292 is a binocular upright microscope built on the B-290 series brightfield platform. It is designed for routine microscopy in schools, colleges, and general biology laboratories.

All main controls sit close together, so the microscope can be operated with minimal hand movement during long sessions.

N-PLAN Optics

The B-292 uses N-PLAN plan achromatic objectives at 4x, 10x, 40x, and 100x oil, giving 40x to 1000x total magnification through 10x/20 eyepieces.

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

Rackless Double-Layer Stage

The double-layer stage moves 75 x 33 mm on a belt-driven, rackless mechanism, with a vernier scale accurate to 0.1 mm on both axes.

• Anti-scratch painted surface
• Single slide holder

Abbe Condenser and Focus System

A centerable Abbe condenser at N.A. 0.9/1.25 sits under a coaxial coarse and fine focus mechanism with an 18 mm coarse travel and an upper stop to prevent objective-slide contact.

• Adjustable tension on the coarse focus knob
• Slots available for phase contrast or darkfield sliders (optional)

X-LED3 Illumination

Illumination comes from a 3.6 W X-LED3 source with manual brightness control and a fixed color temperature of 6,300 K, rated at more than 65,000 hours of lifetime.

• External power supply, 100-240 Vac input, multi-plug EU/UK/US
• 6 W maximum power draw

Ideal Applications

The B-292 suits routine transmitted-light observation where a straightforward binocular setup is enough.

• Secondary school and university biology teaching
• Routine histology and botany samples
• General laboratory brightfield observation
• Training environments with standard glass slides

Choose the B-292 when:

• You need a straightforward binocular brightfield microscope
• Your work does not require infinity-corrected optics
• You want the lowest-cost entry point into the B-290 series
• You may add darkfield or phase contrast sliders later

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-292 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.
