Product Description
OPTIKA B-293PLi
Trinocular Laboratory Microscope with IOS Optics
The B-290 series microscopes are the result of a perfect fusion of experience and design, developed for both educational and routine laboratory use. The OPTIKA B-293PLi represents the top of the line, combining a trinocular head for digital imaging with the superior Infinity Corrected Optical System (IOS). Featuring high-quality IOS N-PLAN objectives, it delivers perfectly flat, sharp images, making it the ultimate choice for demanding applications that require both direct observation and digital documentation. Its powerful and uniform X-LED³ illumination system ensures crisp, clear visuals.
Ergonomic and Reliable Performance
Built with high-quality materials and a modern, ergonomic design, the B-293PLi is made to last. It features a rackless mechanical stage for safe and smooth sample movement, coaxial coarse and fine focusing for precise control, and an Abbe condenser for optimal illumination adjustment. This model is the premier high-performance solution for laboratories requiring both superior optical quality and camera connectivity.

|
OPTIKA is proud to introduce its exclusive X-LED³ lighting source. A special combination of high-efficiency LEDs and a special optical system allows OPTIKA to double the light intensity generated by a standard LED. The resulting light is comparable to the light generated by a 50W halogen lamp but with a color temperature of 6300K, representing sunlight. |

Mechanical Stage Rackless Stage for Safety and Durability The B-290 series is equipped with a modern rackless mechanical stage. This design prevents the rack from protruding from the stage, avoiding potential scratches or injuries during use. The movement is smoother, more reliable, and provides a safer working environment, especially in educational settings. |
Laboratory Grade Optics, N-PLAN & IOS N-PLAN System
OPTIKA N-PLAN objectives ensure bright, clear images with excellent flatness and compensation for chromatic aberration. IOS Infinity-corrected optical system prevents image deterioration even if other optical components are added, such as polarizers, beamsplitters and so on.

Large Specimen View (20 mm Field Number) The F.O.V. (field of view) is based on a comfortable diameter of 20 mm. This means that a wide area of the sample can be inspected and allows a natural and easy view, particularly needed in a laboratory environment. |
Clear Observation With 100x Objective
Users will enjoy B-290 Series for the clear and sharp images they can get using 100x objective with water, thanks to the extremely bright X-LED3 light source and the fully centerable Abbe condenser. Forget about the tedious lens cleaning you are used to when using 100x objective: dirt and dust will not affect your objective.
