Optika B-292PLi Binocular Brightfield Microscope with Infinity-Corrected Optics

The Optika B-292PLi is a binocular upright microscope built on the B-290 series brightfield platform, using an IOS infinity-corrected optical system instead of the finite 160 mm system of the standard B-292.

The infinity design lets the laboratory add optical accessories such as polarizers or beamsplitters to the light path without image quality loss.

IOS N-PLAN Optics

The B-292PLi uses IOS 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
• Slots available for optional phase contrast or darkfield sliders

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

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

Ideal Applications

The B-292PLi suits laboratories that want infinity-corrected optics without moving to a higher series.

• Routine biology and histology with future accessory plans
• Laboratories planning to add polarizing sets
• General laboratory brightfield observation
• Training environments needing stable image quality

Choose the B-292PLi when:

• You want infinity-corrected optics at a B-290 series price point
• You plan to add polarizers or beamsplitters later
• You need a binocular head rather than trinocular
• You do not need a camera port

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-292PLi 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.
