Optika B-293LD1.50 Trinocular LED Fluorescence Microscope

The Optika B-293LD1.50 is a trinocular upright microscope built on the B-290 series infinity-corrected platform, equipped for both brightfield and LED fluorescence observation up to 500x total magnification.

The system supports reflected-light fluorescence alongside standard transmitted brightfield, with a third port for camera attachment.

IOS N-PLAN / W-PLAN Optics

The B-293LD1.50 uses IOS N-PLAN/W-PLAN objectives at 10x, 20x, 40x, and 50x, giving 100x to 500x total magnification through 10x/20 eyepieces.

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

Trinocular Head with Blue Filterset

The trinocular Siedentopf head splits light 50/50 between the eyepieces and the photo port, with an interpupillary range of 55 to 75 mm, and includes a blue filterset for fluorescence work.

• 30 degrees inclined, 360 degrees rotating
• Reflected-light fluorescence observation method

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 Transmitted Illumination

Transmitted light 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-293LD1.50 suits laboratories that need fluorescence screening at lower magnification together with documentation.

• Combined brightfield and fluorescence teaching or research labs with imaging needs
• Fluorescence screening at 500x or below
• General biology work needing a single, dual-technique microscope
• Training environments introducing fluorescence microscopy with documentation

Choose the B-293LD1.50 when:

• You need brightfield and LED fluorescence up to 500x with a camera port
• You want the blue filterset included rather than purchased separately
• You need a trinocular head rather than binocular
• You want infinity-corrected optics for future accessory additions

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-293LD1.50 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.
