Product Description
OPTIKA B-510PH
Binocular Phase Contrast Microscope (IOS W-PLAN PH)
The OPTIKA B-510PH is a professional laboratory microscope from the high-end B-500 series, specifically configured for the observation of transparent, unstained samples using Phase Contrast and Darkfield. It features a modern Binocular head and superior IOS W-PLAN PH (Infinity Corrected) objectives. With its wide field of view (FN 22) and Full Koehler illumination, it is the ideal tool for analyzing live cells, bacteria, and tissue cultures with exceptional clarity.
Advanced Phase Contrast & Full Koehler Illumination
Designed for versatility, the B-510PH is equipped with a professional Full Koehler illumination system and the exclusive X-LED³ source for bright, stable light. It includes a specialized 5-position phase contrast condenser (Brightfield, Darkfield, 10x, 20x, 40x, 100x phase annuli), allowing seamless switching between observation methods. The rackless mechanical stage ensures safe operation, while the optics deliver high-contrast images without halos.

|
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-500 series is equipped with a large, modern rackless mechanical stage (233x147 mm). 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. |
IOS W-PLAN PH Objectives & Wide Field of View
The B-510PH features premium IOS W-PLAN PH objectives, specifically designed for phase contrast to maximize contrast and flatness. Coupled with WF10x/22mm eyepieces, this system offers a wide field number (FN 22), providing a large and immersive view of the specimen.
