Product Description
OPTIKA B-383LD
Trinocular LED Fluorescence Microscope
Part of the advanced B-380 series, the OPTIKA B-383LD is a powerful and versatile microscope for laboratories requiring both brightfield and LED fluorescence capabilities. It features a trinocular head for easy digital camera connection, a robust quintuple nosepiece, and high-quality IOS (Infinity Corrected) N-PLAN objectives. Its dual illumination system includes the bright X-LED³ for transmitted light and an integrated high-power LED for epi-fluorescence, offering a cost-effective and immediate solution for on-field diagnosis.
Ergonomic and Versatile Performance
Built for reliability, the B-383LD features a large 233x147mm rackless mechanical stage for safe and precise sample handling. Its key advantage is the slider with positions for both brightfield and fluorescence, allowing users to switch observation methods instantly without complex setup, making it an incredibly versatile tool for diagnostic laboratories.

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

Mechanical Stage Rackless Stage for Safety and Durability This model is equipped with a large 233x147 mm rackless mechanical stage. This design prevents the rack from protruding, avoiding potential scratches or injuries during use. The movement is smoother, more reliable, and provides a safer working environment. |
Laboratory Grade Optics & LED Fluorescence
This model is equipped with high-quality IOS (Infinity Corrected) N-PLAN objectives. The epi-fluorescence attachment uses a high-efficiency LED that requires no warm-up/cool-down time and has a long lifespan. The included blue filter set is suitable for a variety of common fluorochromes.

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. |
Dedicated LED Fluorescence System
The B-383LD offers an ultra-convenient LED fluorescence solution. Unlike traditional HBO mercury lamps, the LED illuminator provides immediate operation with no waiting time. This cost-effective technology eliminates the need for lamp replacements and centering, saving both time and money while providing excellent performance for diagnostic applications like viewing Auramine O (for Tuberculosis) and other fluorochromes.
