Product Description
OPTIKA B-383DK
Trinocular Darkfield Microscope (Oil Immersion)
Part of the advanced B-380 series, the OPTIKA B-383DK is a high-performance microscope designed specifically for oil immersion darkfield applications, such as live blood analysis. It also fully supports standard brightfield observation. It features a trinocular head for digital documentation, high-quality objectives including a W-PLAN 100x objective with an integrated iris, and a unique dual-condenser system.
Exclusive Darkfield Illumination
This model's key feature is its dedicated N.A. 1.36 oil immersion darkfield condenser with a built-in X-LED³ illuminator. This system provides powerful, high-contrast illumination, achieving results comparable to expensive 150W external light sources. A separate Abbe condenser is included for standard brightfield work, making this a versatile and powerful tool for specialized diagnostic labs.
| X-LED³ Exclusive Lighting System |
|  | ||
| 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-380 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 for High Contrast
This model includes N-PLAN objectives for brightfield and a high-performance W-PLAN 100x oil objective with an integrated iris diaphragm, which is essential for achieving proper oil immersion darkfield illumination.
 | 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. |
Dual Condenser System
The B-383DK is supplied with two separate condensers to ensure optimal performance in both observation modes:
- Brightfield Condenser: Abbe N.A. 1.25, with objective-coded iris diaphragm, focusable and centerable.
- Darkfield Condenser: N.A. 1.36 (oil immersion) condenser with a powerful, built-in X-LED³ illuminator, designed for high-resolution darkfield analysis.
