Optika B-293PLi Trinocular Brightfield Microscope with Infinity-Corrected Optics

The Optika B-293PLi is a trinocular upright microscope built on the B-290 series brightfield platform, using an IOS infinity-corrected optical system and a third port for camera attachment.

The infinity design lets the laboratory add optical accessories such as polarizers or beamsplitters without image quality loss, while the trinocular port supports documentation.

IOS N-PLAN Optics

The B-293PLi 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

Trinocular Head with Camera Port

The trinocular Siedentopf head splits light 50/50 between the eyepieces and the photo port, with an interpupillary range of 55 to 75 mm.

• 30 degrees inclined, 360 degrees rotating
• Diopter adjustment on both tubes

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
• Centerable Abbe condenser, N.A. 0.9/1.25

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-293PLi suits laboratories that need documentation together with infinity-corrected optics.

• Routine biology and histology with documentation needs
• Laboratories planning to add polarizing sets
• General laboratory brightfield observation with camera capture
• Training environments needing stable, expandable optics

Choose the B-293PLi when:

• You need both a camera port and infinity-corrected optics
• You plan to add polarizers or beamsplitters later
• You want the same optics as the B-292PLi with trinocular output
• You do not need a digital camera and tablet built in

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-293PLi 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.
